Strauss FJ, Gil A, Smirani R, Rodriguez A, Jung R, Thoma D. The use of digital technologies in peri-implant soft tissue augmentation - A narrative review on planning, measurements, monitoring and aesthetics. Clin Oral Implants Res 2024. [PMID: 38308466 DOI: 10.1111/clr.14238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 11/21/2023] [Accepted: 01/11/2024] [Indexed: 02/04/2024]
Abstract
OBJECTIVE To identify the different uses and modalities of digital technologies to diagnose, plan and monitor peri-implant soft tissue conditions and aesthetics. METHODS A comprehensive narrative review of pertinent literature was conducted, critically appraising key digital technologies that may assist peri-implant soft tissue augmentation and assessment. An electronic search on four databases including studies published prior to 1st July 2023 was performed and supplemented by a manual search. RESULTS Predominantly, tools such as cone beam computed tomography (CBCT), intraoral scanning (iOS), intraoral ultrasonography and digital spectrophotometry were commonly to assess and monitor peri-implant soft tissues. The main clinical and research applications included: (i) initial assessment of mucosal thickness, supra-crestal tissue height and keratinized mucosa width, (ii) evaluation of peri-implant soft tissue health and inflammation, (iii) monitoring profilometric changes and midfacial mucosal margin stability over time and (iv) aesthetic evaluation through colour assessment. While evidence for some digital tools may be limited, the integration of digital technologies into peri-implant soft tissue management holds great promise. These technologies offer improved precision, comfort and speed in assessment, benefiting both patients and clinicians. CONCLUSION As digital technologies progress, their full potential in peri-implant soft tissue augmentation and their value will become more evident with ongoing research. Embracing these innovations and their potential benefits is recommended to ensure that during progress in implant dentistry, patient care is not hindered.

Tavelli L, Kripfgans OD, Chan HL, Vera Rodriguez M, Sabri H, Mancini L, Wang HL, Giannobile WV, Barootchi S. Doppler ultrasonographic evaluation of tissue revascularization following connective tissue graft at implant sites. J Clin Periodontol 2023. [PMID: 37861110 DOI: 10.1111/jcpe.13889] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 09/06/2023] [Accepted: 09/26/2023] [Indexed: 10/21/2023]
Abstract
AIM To assess the Doppler ultrasonographic tissue perfusion at dental implant sites augmented with connective tissue graft (CTG) using coronally advanced flap (CAF) or tunnel technique (TUN). MATERIALS AND METHODS Twenty-eight patients presenting with isolated healthy peri-implant soft-tissue dehiscence (PSTD) were included in this randomized clinical trial. PSTDs were treated with either CAF + CTG or TUN + CTG. Ultrasound scans were taken at baseline, 1 week, 1 month, 6 months and 12 months. Tissue perfusion at the mid-facial, mesial and distal aspects of the implant sites was assessed by colour Doppler velocity (CDV) and power Doppler imaging (PDI). Early vascularization of the graft and the flap at 1 week and at 1 month were evaluated via dynamic tissue perfusion measurements (DTPMs), including flow intensity (FI), mean perfusion relief intensity (pRI) and mean perfused area (pA). RESULTS Regression analysis did not reveal significant differences in terms of mid-facial CDV and PDI changes between CAF and TUN over 12 months (p > .05), while significant differences between the two groups were observed at the interproximal areas (p < .001 for both CDV and PDI changes). Higher early DTPMs were observed at the TUN-treated sites in terms of mean FI of the graft (p = .027) and mean FI (p = .024) and pRI of the flap (p = .031) compared with CAF-treated sites at 1 week. Assessment of the FI direction showed that CTG perfusion at 1 week and at 1 month mainly occurred from the flap towards the implant/bone. Early tissue perfusion outcomes were found to be associated with the 12-month mean PSTD coverage and mucosal thickness gain. CONCLUSIONS Doppler ultrasonography shows tissue perfusion changes occurring at implant sites augmented with CTG. The main differences in tissue perfusion between CAF and TUN were observed at the interproximal sites, with early perfusion associated with clinical and volumetric outcomes at 12 months.

Does vestibular incision improve the outcomes of vestibular incision subperiosteal tunnel technique: A randomized clinical trial for treatment of multiple adjacent type 1 gingival recession. J ESTHET RESTOR DENT 2023; 35:1131-1138. [PMID: 37078417 DOI: 10.1111/jerd.13051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 03/27/2023] [Accepted: 03/31/2023] [Indexed: 04/21/2023]
Abstract
OBJECTIVE The purpose of this study was to compare the clinical outcomes of vestibular incision subperiosteal tunnel technique (VISTA) and tunnel approach combined with connective tissue graft (CTG) for treatment of type 1 (RT1) multiple gingival recession. MATERIALS AND METHODS Twenty-four patients with a total of 59 nonmolar recession teeth were randomly allocated to VISTA + CTG or Tunnel + CTG group. Recession depth and width, probing depth, clinical attachment level, width of keratinized tissue, gingival thickness, flap tension, mean root coverage (MRC), complete root coverage (CRC), patient-centered, and esthetic outcomes (root coverage esthetic scores, RES) were assessed at baseline and 12 months after surgery. RESULTS At 12 months, MRC of 91.13 ± 16.96% and 91.40 ± 13.53%, CRC of 70.97% and 67.86% were observed for VISTA + CTG and Tunnel + CTG group respectively, with no significant difference between the two groups (p > 0.05). High RES of 8.52 ± 1.46 and 8.82 ± 1.44 was obtained in VISTA + CTG and Tunnel + CTG group respectively, without showing a significant difference (p = 0.245), while less scar formation was observed in Tunnel + CTG group (p < 0.01). CONCLUSIONS Both procedures were effective for root coverage in RT1 multiple gingival recession at 12 months. Better esthetic result with less scar formation was obtained in tunnel approach combined with CTG without vestibular incision. (Registration number: ChiCTR-INR-16007845, registered on 19/12/2015, http://www.chictr.org.cn). CLINICAL SIGNIFICANCE VISTA + CTG and Tunnel + CTG were both effective for root coverage in RT1 multiple gingival recession, with satisfying esthetic outcomes. However, it is suggested in critical esthetic areas, treatment options of making vertical incisions should be carefully considered.

Coronally advanced flap versus tunnel technique for the treatment of peri-implant soft tissue dehiscences with the connective tissue graft: A randomized, controlled clinical trial. J Clin Periodontol 2023; 50:980-995. [PMID: 36935199 DOI: 10.1111/jcpe.13806] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 02/27/2023] [Accepted: 03/10/2023] [Indexed: 03/21/2023]
Abstract
AIM To evaluate the efficacy of coronally advanced flap (CAF) versus tunnel technique (TUN) in covering isolated mid-facial peri-implant soft tissue dehiscences (PSTDs). MATERIALS AND METHODS Twenty-eight participants presenting with isolated non-molar implants exhibiting PSTDs were enrolled and randomized to receive either CAF or TUN, both with a connective tissue graft (CTG). The primary outcome of the study was the percentage of mean PSTD coverage at 12 months. Secondary endpoints included the frequency of complete PSTD coverage, changes in keratinized mucosa width (KMW) and horizontal mucosal thickness (MT), as assessed with transgingival probing, 3D optical scanning and ultrasonography, professional aesthetic evaluation and patient-reported outcome measures (PROMs). RESULTS At 12 months, the mean PSTD coverage of the CAF and TUN groups was 90.23% and 59.76%, respectively (p = .03). CAF-treated sites showed a substantially higher frequency of complete PSTD coverage (p = .07), together with significantly greater gain of KMW (p = .01), increase in MT (p = .02), volumetric gain (p < .01) and professional aesthetic outcomes (p = .01). Both interventions showed an improvement in patient-reported aesthetics and a reduction of the anxiety related to the appearance of the implant compared to baseline, with the CAF group obtaining significantly higher scores (p = .03 for both PROMs). CONCLUSIONS CAF + CTG resulted in superior PSTD coverage outcomes, greater gain in KMW and MT, and better PROMs than TUN + CTG for the treatment of isolated PSTDs (ClinicalTrials.gov NCT03498911).

Clin Oral Investig 2023:10.1007/s00784-023-04975-7. [PMID: 36988824 DOI: 10.1007/s00784-023-04975-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 03/20/2023] [Indexed: 03/30/2023]
Abstract
OBJECTIVE To evaluate the efficacy of the partial-thickness non-advanced tunnel technique (TUN) versus the coronally advanced flap (CAF), both combined with a connective tissue graft, in the treatment of multiple gingival recessions. MATERIALS AND METHODS Twenty-nine patients (83 teeth) affected by multiple gingival recessions were treated in two clinical centers with either the test (TUN) or the control (CAF) intervention combined with a connective tissue graft. Outcomes at 3 and 6 months after surgery included complete root coverage (CRC-primary outcome), mean root coverage (mRC), changes in recession depth (RD), probing pocket depth (PPD), and keratinized tissue height (KT). Root sensitivity and root coverage esthetic score (RES) were also evaluated at 6-month examination. Surgery duration, wound healing index (WHI), and patient-reported outcome measures (PROMs) were additionally considered. RESULTS At 6 months, CRC was observed in 80.9% and 79.5% of the teeth treated with TUN and CAF, respectively (odds ratio = 1.2; p = 0.802). No differences between groups were also observed in terms of mRC (TUN = 94.0%; CAF = 91.1%), RD and PPD reductions, root sensitivity, RES, and WHI. KT increase was significantly higher in teeth treated with TUN (Difference in Means - MD = - 1.0 mm; p = 0.001). Surgery duration was shorter (MD = - 19.3 min; p = 0.001), and patients reported less intra-surgical pain (MD = - 16.4; p = 0.028) as well as postoperative morbidity in TUN compared with CAF. CONCLUSIONS Both surgical interventions showed a similar efficacy in terms of root coverage, albeit TUN was associated with a higher increase in KT and with a milder patient's surgical experience. CLINICAL RELEVANCE Both techniques have shown similar efficacy for the coverage of exposed root surfaces, although clinicians may consider TUN as less invasive.

Chambrone L, Barootchi S, Avila-Ortiz G. Efficacy of biologics in root coverage and gingival augmentation therapy: An American Academy of Periodontology best evidence systematic review and network meta-analysis. J Periodontol 2022; 93:1771-1802. [PMID: 36279123 DOI: 10.1002/jper.22-0075] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND The aim of this systematic review was to assess the efficacy of three biologics, namely autologous blood-derived products (ABPs), enamel matrix derivatives (EMD) and recombinant human platelet-derived growth factor BB (rhPDGF-BB), in root coverage and gingival augmentation therapy. METHODS The protocol of this PRISMA 2020-compliant systematic review was registered in PROSPERO (CRD42021285917). After study selection, data of interest were extracted. A network meta-analysis (NMA) was conducted to assess the effect of different surgical interventions on the main clinical outcomes of interest (i.e., mean root coverage [MRC%], complete root coverage [CRC%], keratinized tissue width [KTW], gingival thickness [GT] change, and recession depth [RD] reduction). RESULTS A total of 48 trials reported in 55 articles were selected. All studies reported on the treatment of gingival recession defects for root coverage purposes. Forty-six treatment arms from 24 trials were included in the NMA. These arms consisted of treatment with coronally advanced flap (CAF) alone, EMD + CAF, platelet-rich fibrin (PRF) + CAF, and subepithelial connective tissue graft (SCTG) + CAF. Regarding MRC%, SCTG+CAF was associated with a significant higher estimate (13.41%, 95% CI [8.06-18.75], P < 0.01), while EMD+CAF (6.68%, 95% CI [-0.03 to 13.4], P = 0.061) and PRF+CAF (1.03%, 95% CI [-5.65 to 7.72], P = 0.71) failed to show statistically significant differences compared with CAF alone (control group) or with each other. Similarly, only SCTG+CAF led to a significantly higher CRC% (14.41%, 95% CI [4.21 to 24.61], P < 0.01), while treatment arms EMD + CAF (13.48%, 95% CI [-3.34 to 30.32], P = 0.11) and PRF+CAF (-0.91%, 95% CI [-15.38, 13.57], p = 0.81) did not show significant differences compared with CAF alone or with each other. Differences in the CI of PRF+CAF (symmetrical around a zero adjunctive effect) and EMD+CAF (non-symmetrical) suggest that EMD could have some additional value compared with PRF. Treatment with SCTG+CAF led to a statistically significant higher RD reduction (-0.39 mm, 95% CI [-0.55 to 0.22], P < 0.01), however EMD+CAF (-0.13 mm, 95% CI [-0.29 to 0.01], P = 0.08) and PRF+CAF (-0.06 mm, 95% CI [-0.23 to 0.09], P = 0.39) failed to show significant differences compared with CAF or with each other. While SCTG+CAF was associated with a statistically significant higher gain of KTW (0.71 mm, 95% CI [0.48 to 0.93], P < 0.01), EMD+CAF (0.24 mm, 95% CI [-0.02 to 0.51], P = 0.08) and PRF+CAF (0.08 mm, 95% CI [-0.23 to 0.41], P = 0.58) did not result into significant changes compared with CAF alone or with each other. Regarding the use of rhPDGF-BB+CAF, although available studies have reported equivalent results compared with SCTG+CAF, evidence is very limited. CONCLUSIONS The use of ABPs, EMD, or rhPDGF-BB in conjunction with a CAF for root coverage purposes is safe and generally promotes significant improvements respective to baseline clinical parameters. However, the adjunctive use of ABPs and EMD does not provide substantial additional improvements in terms of clinical outcomes and patient-reported outcome measures to those achieved using CAF alone, when baseline KTW is >2 mm. Both PRF+CAF and EMD+CAF rendered inferior MRC%, CRC%, RD reduction, and KTW gain compared with SCTG+CAF, which should still be considered the gold-standard in root coverage therapy. Although some studies have reported equivalent results for rhPDGF-BB+CAF compared with the gold-standard intervention, limited evidence precludes formal comparisons with CAF or SCTG+CAF that could be extrapolated to guide clinical practice.

Patient and professional use of the root coverage esthetic score (RES) and how it relates to patient satisfaction following periodontal plastic surgery. BMC Oral Health 2022; 22:295. [PMID: 35850680 PMCID: PMC9290205 DOI: 10.1186/s12903-022-02326-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 07/07/2022] [Indexed: 11/22/2022] Open
Abstract
Background Following periodontal plastic surgery in the treatment of recession defects, previous studies have reported that patients rate the esthetic outcomes more favorable than dental professionals. The root coverage esthetic score has been developed and suggested to serve as a comprehensive assessment instrument as it addresses several esthetic outcomes following root coverage procedures. However, no study has yet reported on patient use of this instrument. In the present study clinical, esthetic and patient-reported outcomes following periodontal plastic surgery were assessed. The primary objective was to compare the esthetic/clinical outcome as judged by the patient and by one dentist by using the root coverage esthetic score. The secondary objective was to evaluate the correlation between patient-reported outcomes, root coverage esthetic score and clinical parameters following treatment of recession defects. Materials and methods Subjects that had undergone periodontal plastic surgery were invited to score the treatment outcome according to the root coverage esthetic score, which subsequently also was professionally scored by a dentist. Thereafter, the subjects answered a questionnaire on patient satisfaction. All types of surgical root coverage procedures in canine or incisor teeth were included. Results A total of 34 subjects were included, presenting 46 treated recessions. No statistically significant different score was found comparing the root coverage esthetic score by the patient and the professional. The majority of subjects was satisfied with the treatment outcome, and most would have undergone the treatment again. Conclusion The root coverage esthetic score assessment can be conducted by patients and was not statistically significant different to that of the professional. Patient satisfaction is not always dependent on complete root coverage or the other clinical parameters included in the root coverage esthetic score.

Abstract
Background Despite many advances in dentistry, no objective and quantitative method is available to evaluate gingival shape. The surface curvature of the optical scans represents an unexploited possibility. The present study aimed to test surface curvature estimation of intraoral scans for objective evaluation of gingival shape. Methods The method consists of four main steps, i.e., optical scanning, surface curvature estimation, region of interest (ROI) definition, and gingival shape analysis. Six different curvature measures and three different diameters were tested for surface curvature estimation on central (n = 78) and interdental ROI (n = 88) of patients with advanced periodontitis to quantify gingiva with a novel gingival shape parameter (GS). The reproducibility was evaluated by repeating the method on two consecutive intraoral scans obtained with a scan-rescan process of the same patient at the same time point (n = 8). Results Minimum and mean curvature measures computed at 2 mm diameter seem optimal GS to quantify shape at central and interdental ROI, respectively. The mean (and standard deviation) of the GS was 0.33 ± 0.07 and 0.19 ± 0.09 for central ROI using minimum, and interdental ROI using mean curvature measure, respectively, computed at a diameter of 2 mm. The method’s reproducibility evaluated on scan-rescan models for the above-mentioned ROI and curvature measures was 0.02 and 0.01, respectively. Conclusions Surface curvature estimation of the intraoral optical scans presents a precise and highly reproducible method for the objective gingival shape quantification enabling the detection of subtle changes. A careful selection of parameters for surface curvature estimation and curvature measures is required.

Modified coronally advanced tunnel versus epithelialized free gingival graft technique in gingival phenotype modification: a comparative randomized controlled clinical trial. Clin Oral Investig 2022; 26:6283-6293. [PMID: 35708779 DOI: 10.1007/s00784-022-04580-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 06/07/2022] [Indexed: 11/03/2022]
Abstract
OBJECTIVES The gingival thickness (GT) and keratinized tissue (KT) height are defined as the gingival phenotype. Both the modified coronally advanced tunnel technique (MCAT) and free gingival grafts (FGG) are used in modifying the gingival phenotype. This study aims to compare MCAT and FGG in gingival phenotype modification. MATERIALS AND METHODS One hundred and forty recessions in 50 patients with thin and insufficient keratinized tissue at the anterior mandible were treated with either MCAT or FGG. GT, KT height, recession depth, recession width, probing depth, and clinical attachment level were evaluated at baseline and 6 weeks, 6 months, and 12 months. GT change, KT change, root coverage (RC), clinical attachment gain, and complete root coverage (CRC) were calculated. The wound healing index, tissue appearance, patient expectations, aesthetic, and dentin hypersensitivity were assessed at baseline and 6 months. RESULTS All periodontal variables showed significant change from baseline to 12 months in both groups (p < 0.05). While FGG resulted in more KT change (p < 0.001), all MCAT sites showed at least 2 mm KT change in 12 months. MCAT resulted in greater GT change (p < 0.05) and RC (p < 0.003). In contrast, there was no significant inter-group CRC difference (p = 0.523). All patient-based variables were favorable to MCAT (p < 0.05), except dentin hypersensitivity (p = 0.225). CONCLUSIONS Both techniques were successful in terms of gingival phenotype modification in the anterior mandible. Additional GT increase, RC, and patient-based outcomes favored MCAT, though KT change proved greater with FGG. CLINICAL RELEVANCE Clinicians may choose MCAT for higher GT increase whereas FGG for more KTC. TRIAL REGISTRATION NUMBER NCT04690140 and date: 12/26/2020.

Abstract
Gingival recessions are a prevalent oral mucosa alteration. To solve this pathology, palatal mucosa or polymeric soft tissue substitutes are used when performing coronal advanced flap (CAF) or tunnel (TUN) surgical techniques. To evaluate which is the most successful approach, a literature review and meta-analysis were conducted. For the electronic search the National Library of Medicine, the Cochrane Oral Health Group Trials Register, EMBASE and WOS were used. Pooled data for the percentage of root coverage was collected and weighted means were calculated. Heterogeneity was determined using the Higgins (I2) statistic and a random-effects model was applied. Thirteen studies were included in the systematic review (12 randomized and 1 controlled clinical trials) in which both techniques (394 patients) were compared with a follow-up of 4 to 12 months. Galbraith and Baujat plots were used to control for the presence of potential outliers. After performing the meta-analysis (11 studies), the mean root coverage was similar when using the TUN or CAF techniques (p = 0.49). The only differences between the two were found for single recessions, where CAF offered a higher percentage of root coverage (mean difference = 4.98%; p = 0.006). There were no differences when applying an autograft or a polymeric substitute with either of the two tested surgical techniques (p = 0.445).

Abstract
OBJECTIVES The present study aimed to compare the conventional clinical and digital methods evaluating differences in gingival recession (ΔREC) in patients with advanced periodontitis treated with the non-surgical treatment protocol. METHODS Agreement between the methods was evaluated on a sample of ten patients with periodontitis (stage III/IV, grade B/C) with acquired clinical measurements and digital models from baseline (T0) and 12-months after non-surgical treatment of periodontitis (T1). The evaluation was performed on maxillary teeth from right to left second premolar resulting in overall 99 teeth. Clinical evaluation was performed by subtracting the distance measurements between gingival margin and cemento-enamel junction, obtained at T0 and T1 by a calibrated examiner (intra-examiner agreement >90%). The digital evaluation was performed directly by measuring the distance between the gingival margins on superimposed T0 and T1 digital models. Using Bland-Altman and statistical analysis, all six measurements sites around each included tooth (n=594) acquired with both methods were compared. RESULTS Median ΔREC (5th and 95th percentile) acquired with a conventional clinical and digital method was 0.0mm (-2.0 - 1.0) and -0.4mm (-1.6 - 0.8), respectively (p<0.0001). The complete agreement between rounded digital and clinical ΔREC values was only 38%, revealing high disagreement also confirmed by Bland-Altman analysis with 95% limits of agreement ranging from -2.6 to 1.8mm. Absolute differences between the methods higher than 0.5 and 1 mm, was found in 61% and 38% of measurement sites, respectively. CONCLUSIONS The conventional clinical method for ΔREC evaluation exhibits lower sensitivity and accuracy than the digital method. CLINICAL SIGNIFICANCE The quality of both clinical and research data in periodontology and implantology can be considerably improved by the digital method while still preserving the compatibility with the conventional clinical method.

Abstract
Purpose In this study, we aimed to evaluate the clinical validity of the modified tunneling technique using minimal soft tissue harvesting and volume-stable collagen matrix in the anterior mandible. Methods In total, 27 anterior mandibular teeth and palatal donor sites in 17 patients with ≥1 mm of gingival recession (GR) were analyzed before and after root coverage. For the recipient sites, vertical vestibular incisions were made in the interdental area and a subperiosteal tunnel was created with an elevator. After both sides of the marginal gingiva were tied to one another, a prepared connective tissue graft and volume-stable collagen matrix were inserted through the vestibular vertical incision and were fixed with resorbable suture material. The root coverage results of the recipient site were measured at baseline (T0), 3 weeks (T3), 12 weeks (T12), and the latest visit (Tl). For palatal donor sites, a free gingival graft from a pre-decided area avoiding the main trunk of the greater palatine artery was harvested using a prefabricated surgical template at a depth of 2 mm after de-epithelization using a rotating bur. In each patient, the clinical and volumetric changes at the donor sites between T0 and T3 were measured. Results During an average follow-up of 14.5 months, teeth with denuded root lengths of 1–3 mm (n=12), 3–6 mm (n=11), and >6 mm (n=2) achieved root coverage of 97.01%±7.65%, 86.70%±5.66%, and 82.53%±1.39%, respectively. Miller classification I (n=12), II (n=10), and III (n=3) teeth showed mean coverage rates of 97.01%±7.65%, 86.91%±5.90%, and 83.19%±1.62%, respectively. At the donor sites, an average defect depth of 1.41 mm (70.5%) recovered in 3 weeks, and the wounds were epithelized completely in all cases. Conclusions The modified tunneling technique in this study is a promising treatment modality for overcoming GR in the anterior mandible.

Abstract
OBJECTIVE Due to the minimal blood supply and other reasons, stable reconstruction of interdental papilla is difficult. This article presented three cases, which describe a customized subepithelial connective tissue graft aiming to overcome the clinical challenge, with the combination of tunneling technique. CLINICAL CONSIDERATIONS An original customized subepithelial connective tissue graft combined with tunnel technique aimed to reconstruct interdental papilla (IP). The subepithelial connective tissue graft was partially spilt to create a bowtie-like shape, with four lateral wings and a main body. The four wings were tightly wrapped around the adjacent abutments, and the body part was used to reconstruct the IP. CONCLUSIONS With the customized subepithelial connective tissue graft, a favorable outcome has been preliminarily confirmed in these cases. Facing patients with a lack of gingival papilla and soft tissue fullness, the customized subepithelial connective tissue graft may be a good choice. CLINICAL SIGNIFICANCE This study provides a new method to reconstruct IP. The customized subepithelial connective tissue graft may be a good choice when a lack of gingival papilla and soft tissue fullness occurs, which will be of great benefit to meet the aesthetic needs of patients.

Abstract
AIM To introduce and validate a computer-aided method for direct measurements and visualization of gingival margin (GM) changes. MATERIALS AND METHODS The method consists of five main steps: digital model acquisition, superimposition, computer-aided GM detection, distance calculation between the GM curves, and visualization. The precision of the method was evaluated with repeatability and reproducibility analysis (n = 78 teeth). The method's repeatability was evaluated by repeating the algorithm on the same digital models by two operators. The reproducibility was evaluated by repeating the algorithm on two consecutive digital models obtained with a scan-rescan process at the same time point on the same patient. For demonstration, the proposed method for direct measurements of GM changes was performed on patients who had undergone root coverage procedures and treatment of periodontal disease. RESULTS Excellent repeatability was found for both intra- and inter-operator variability, that is, 0.00 mm, regarding computer-aided GM detection. The reproducibility of computer-aided GM detection evaluated on scan-rescan models was 0.10 mm. CONCLUSIONS The presented method enables the evaluation of GM changes in a simple, precise, and comprehensive manner through non-invasive acquisition and superimposition of digital models.

Abstract
AIM The objective of this network meta-analysis was to rank different biomaterials used in adjunct to coronally advanced flap (CAF), based on their performance in root-coverage for Miller's Class I and II gingival recessions. MATERIALS AND METHODS An electronic database search was carried out in PUBMED, CENTRAL, SCOPUS, and EMBASE to identify the eligible articles and compiled into the citation manager to remove the duplicates. The primary outcome was keratinized gingival tissue width (KGW) and percentage of root coverage (%RC). The treatment effect of different biomaterials was estimated using predictive interval plots and ranked based on biomaterials performance, using multidimensional scale ranking. RESULTS CAF + connective tissue graft (CTG), CAF + platelet concentrate matrix (PCM) and acellular dermal matrix (ADM) ranked at the top positions in performance in improving KGW. The highest ranked materials in improving percentage of root coverage in gingival recession were CAF + collagen matrix (CM) + gingival fibroblasts (GF), CAF + ADM + platelet rich plasma (PRP) and CAF + ADM, as compared to CAF alone. CONCLUSION CTG, ADM, platelet concentrates, and CM + GFs, when used in adjunct to CAF, showed improved stability over ≥12 months of follow-up, better percentage of root coverage, and improved keratinized gingival width.

Abstract
The understanding of biological concepts in wound healing together with the evolution in biomaterials applied in periodontal regeneration allowed for improved, minimally invasive surgical techniques with a wider range of application and adapted to achieve multiple goals at the same time. Regenerating attachment was never the sole end point, but maintaining the patient's own natural dentition in health and esthetics is becoming a feasible goal even in cases considered challenging just a few years ago. In this article we report on the evolution of techniques and biomaterials and their application in esthetic and challenging cases.

Abstract
Background
The extent of gingival recession represents one of the most important measures determining outcome of periodontal plastic surgery. The accurate measurements are, thus, critical for optimal treatment planning and outcome evaluation. Present study aimed to introduce automated curvature-based digital gingival recession measurements, evaluate the agreement and reliability of manual measurements, and identify sources of manual variability. Methods Measurement of gingival recessions was performed manually by three examiners and automatically using curvature analysis on representative cross-sections (n = 60). Cemento-enamel junction (CEJ) and gingival margin (GM) measurement points selection was the only variable. Agreement and reliability of measurements were analysed using intra- and inter-examiner correlations and Bland–Altman plots. Measurement point selection variability was evaluated with manual point distance deviation from an automatic point. The effect of curvature on manual point selection was evaluated with scatter plots. Results Bland–Altman plots revealed a high variability of examiner’s recession measurements indicated by high 95% limits of agreement range of approximately 1 mm and several outliers beyond the limits of agreement. CEJ point selection was the main source of examiner’s variability due to smaller curvature values than GM, i.e., median values of − 0.98 mm− 1 and − 4.39 mm− 1, respectively, indicating straighter profile for CEJ point. Scatter plots revealed inverse relationship between curvature and examiner deviation for CEJ point, indicating a threshold curvature value around 1 mm− 1. Conclusions Automated curvature-based approach increases the precision of recession measurements by reproducible measurement point selection. Proposed approach allows evaluation of teeth with indistinguishable CEJ that could be not be included in the previous studies.

Abstract
OBJECTIVES The aim of the present review was to find, compare, and critically discuss digital methods for quantitative evaluation of gingival recessions dimensions. DATA Collection of articles and classification related to digital evaluation of gingival recessions. SOURCES A search of PubMed, Web of Science, Scopus, and reference lists of articles was conducted up to April 2021 STUDY SELECTION: Twenty-two articles used digital evaluation of gingival recessions dimensions. The methods in the included articles were extracted, compared, and categorized. RESULTS Digital measurements were performed on 2D intraoral photographs, 3D models, or cross-sections obtained from 3D models. Baseline measurement were performed for diagnostic and treatment planning and categorised into distance and area measurements. Follow-up evaluation of treatment was based either on repeating the "baseline" measurements and calculating differences or measuring differences directly on composite images, composed from two superimposed images obtained at two time-points. Direct measurements were categorised into distance, area, and volume measurements. CONCLUSIONS Digital evaluation predominantly means just digitalization of the established evaluation methods; therefore, increasing measurements accuracy and maintaining comparability with past studies. At present, a large variability of digital evaluation workflow among the included studies renders the comparison among different studies difficult if not impossible. The potential of digital evaluation seems not to have been fully exploited as only a few novel measurements and parameters introduced, i.e., volumetric evaluation of soft tissue dynamics. For reproducible and comparable studies in the future, the research should be aimed at evaluation, optimization and standardization of all phases of the digital evaluation. CLINICAL SIGNIFICANCE Digital evaluation, based on 3D image superimposition is a promising approach as it increases measurements accuracy, maintains compatibility with past studies and simultaneously introduces novel evaluation possibilities.

Abstract
AIM Comparison of the clinical efficacy (digitally volumetric, aesthetic, patient-centred outcomes) of tunnel technique (TUN) with subepithelial connective tissue graft (CTG) versus coronally advanced flap (CAF) with enamel matrix derivate (EMD) 5 years after gingival recession therapy. MATERIALS AND METHODS In 18 patients contributing 36 RT1 recessions, study models were collected at baseline and follow-ups. Optical scans assessed recessions computer-assisted [recession depth, recession reduction (RECred), complete root coverage (CRC), percentage of root coverage (RC), pointwise (pTHK) and mean areal (aTHK) marginal soft tissue thickness]. Root coverage aesthetic Score (RES) was used for aesthetic evaluation and visual analogue scales for patient-centred data collection applied. RESULTS Sixty months after surgery, 50.0% (TUN+CTG) and 0.0% (CAF+EMD) of sites showed CRC (p = 0.0118), 82.2% (TUN+CTG) and 32.0% (CAF+EMD) achieved RC, respectively (p = 0.0023). CTG achieved significantly better RECred (TUN+CTG: 1.75±0.74 mm; CAF+EMD: 0.50 ± 0.39 mm; p = 0.0009) and aTHK (TUN+CTG: 0.95 ± 0.41 mm; CAF+EMD: 0.26 ± 0.28 mm; p = 0.0013). RES showed superior outcomes (p = 0.0533) for TUN+CTG (6.86 ± 2.31) compared to CAF+EMD (4.63 ± 1.99). The study failed to find significant differences related to patient-centred outcomes (TUN+CTG: 8.30 ± 2.21; CAF+EMD: 7.50 ± 1.51; p = 0.1136). CONCLUSIONS Five years after treatment, CTG resulted in better clinical and aesthetic outcomes than CAF+EMD. Increased THK was associated with improved outcomes for RECred and RC.

Korkmaz B, Balli U. Clinical evaluation of the treatment of multiple gingival recessions with connective tissue graft or concentrated growth factor using tunnel technique: a randomized controlled clinical trial. Clin Oral Investig 2021; 25:6347-6356. [PMID: 33830339 DOI: 10.1007/s00784-021-03935-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 03/30/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To assess the effectiveness of the combination of tunnel technique (TT) and concentrated growth factor (CGF) for root coverage in treating multiple gingival recessions (GR) and compare with the connective tissue graft (CTG). MATERIALS AND METHODS Forty patients with Miller Class I and II maxillary or mandibular GR were randomly divided into two groups as follows: TT + CTG and TT + CGF. The results at baseline and 6 months were evaluated for the following clinical parameters: complete root coverage (CRC), mean root coverage (MRC), gingival thickness (GT), gingival recession width (RW), gingival recession depth (RD), and keratinized tissue width (KTW). RESULTS At 6 months, a statistically significant difference was found in RD, RW, MRC, CRC, KTW, and GT compared with the baseline (p < 0.05). MRC was determined 89.52±16.36% in the TT + CTG and 76.60±24.10% in the TT + CGF (p < 0.05). CRC was achieved in 66.7% of the TT + CTG and 47.4% of the TT + CGF (p < 0.05). The increase in KTW and GT was significantly better in the TT + CTG group compared to the TT + CGF (p < 0.05). CONCLUSIONS The study showed that TT + CGF did not improve the results as much as TT + CTG in the treatment of Miller Class I and II GR. However, this finding is not sufficient to advocate the true clinical effects of CGF on GR treatment with TT. CLINICAL RELEVANCE CGF could not serve as a direct alternative biomaterial to the gold standard CTG. TRIAL REGISTRATION ClinicalTrials.gov Identification Number: NCT04561947.

Abstract
AIM This study aimed to determine the optimal reference area for superimposition of serial 3D dental models of patients with advanced periodontitis. MATERIALS AND METHODS Ten pre- and post-periodontal treatment 3D models (median time lapse: 13.1 months) of patients with advanced periodontitis were acquired by intraoral scanning. Superimposition was performed with the iterative closest point algorithm using four reference areas: (A) all stable teeth, (B) all teeth, (C) third palatal rugae and (D) the whole model. The superimposition accuracy was evaluated at two stable evaluation regions using the mean absolute distance and evaluated with two-way ANOVA and post-hoc multivariate model. The intra- and inter-operator reproducibility was calculated by intraclass correlation coefficient (ICC). RESULTS Superimposition accuracy evaluated at stable tooth evaluation region were 71 ± 29 μm, 73 ± 21 μm, 127 ± 52 μm and 113 ± 53 μm for areas A, B, C and D, respectively. All reference areas showed similarly high ICC values >0.990, except for reference area C showing ICC of 0.821 (intra-operator) and 0.767 (inter-operator) for tooth evaluation area. CONCLUSIONS Area A and B provide the highest accuracy for superimposition of serial 3D dental models acquired by intraoral scanning of patients with advanced periodontitis.

Abstract
OBJECTIVES To introduce an esthetic index for assessing the outcomes of peri-implant soft tissue dehiscence/deficiency (PSTD) coverage and test its within- and between-reviewer reliability. MATERIALS AND METHODS Photographs of 51 single PSTDs at baseline and after treatment were provided to four periodontists from three centers. The examiners were asked to rate each case at two timepoints with the Implant soft tissue Dehiscence/deficiency coverage Esthetic Score (IDES) that involved the evaluation of the post-treatment level of the soft tissue margin, peri-implant papillae height, mucosa color, and mucosa appearance (summing up to a total score of 10). Variance components analysis was conducted using multilevel regression fit in a Bayesian framework for obtaining uncertainty intervals for fractional variance contributions and intraclass correlation values (ICC) of the IDES, and for each of its four clinical variables. RESULTS Regression models showed reproducible esthetic evaluation among the examiners (inter-reliability) and negligible intra-reviewer variability (assessment of the same case at different timepoints). The ICC for the variability in the assessment of the overall IDES was 0.86, and for the individual components ranged from 0.78 to 0.87. Additionally, there was a strong similarity between the raters' IDES values, and their subjective esthetic response, by the same raters. CONCLUSION The IDES showed persistent judgment among the 4 reviewers, and only a slight intra-reviewer variability across timepoints. Within its limitations, this study suggests that the proposed novel score can be a reliable tool for evaluating the esthetic outcomes of PSTD coverage, which can aid in standardization of esthetic assessments following the treatment of a PSTD.

Abstract
OBJECTIVE To address the myths and realities of soft tissue grafting with the tunnel technique in the mandibular anterior region. MATERIALS AND METHODS Myths associated with use of the tunnel technique for soft tissue grafting in the mandibular anterior region are identified and examined. Explanations for the misunderstandings are presented and documented with case examples and evidence from scientific studies. RESULTS Six myths are described and the realities are presented. CONCLUSIONS This report demonstrates that the tunnel technique can be successfully used in the mandibular anterior region in the presence of anatomic features thought to favor the use of more invasive surgical methods. CLINICAL SIGNIFICANCE Soft tissue grafting in the mandibular anterior region has complicating anatomical features including a strong frenal attachment, shallow vestibule and thin tissue. These features may be successfully managed with a free gingival graft, but that procedure results in an uncomfortable experience for the patient. The tunnel technique, especially when combined with an acellular dermal matrix, dramatically improves the patient experience and esthetic outcome without compromising the clinical outcome.

Abstract
PURPOSE The aim of this study was to compare the efficacy of the tunnel technique for root coverage using a new xenogeneic acellular dermal matrix vs. connective tissue grafting (CTG) for the treatment of multiple maxillary adjacent recessions (recession type 1) at 12 months postoperatively. METHODS This study enrolled 12 patients with at least 3 contiguous, bilateral, symmetrical maxillary gingival recessions (i.e., at least 6 recessions per patient). In total, 74 recessions were treated using the modified coronally advanced tunnel (MCAT) technique combined with a novel porcine-derived acellular dermal matrix (PADM) at 37 test sites or CTG at 37 control sites. The following clinical parameters were measured: recession height, clinical attachment level, width of keratinized tissue, probing depth, recession width, gingival thickness, mean root coverage (MRC), and complete root coverage (CRC). Comparisons between test and control groups were made for pain visual analog scale scores at 14 days. RESULTS At 12 months, the MCAT with PADM (test) yielded a statistically significant improvement in all clinical parameters studied. MRC was significantly higher on the control sides (80.6%±23.7%) than on the test sides (68.8%±23.4%). Similarly, CRC was 48.7%±6.8% on the control sides (CTG), in contrast to 24.3%±8.2% on the test sides (PADM). Statistically significant differences were observed in favor of the control sides for all clinical parameters studied. Nevertheless, the MCAT in adjunction with PADM was clearly superior at reducing mean and maximum patient-reported postoperative pain intensity and pain duration in the first week after surgery. CONCLUSIONS The use of PADM to treat multiple recessions improved clinical parameters at 12 months, but these outcomes were nevertheless poorer than those observed for CTG. However, PADM reduced morbidity, particularly the pain experienced by patients. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03162016.

Abstract
The new classification of periodontal diseases recognizes the key role of the interdental clinical attachment for defining the periodontal status and the extent of disease severity. Regenerating interdental clinical attachment not only improves the prognosis of the tooth, but it also lessens the severity of the disease condition. This manuscript provides a state-of-the-art review on surgical reconstructive approaches for treating papillary deficiency associated with soft and hard tissue interproximal defects. Combination therapy of papilla preservation, connective tissue grafting, and coronally advanced flaps may result in regeneration of the intrabony defect coupled with root coverage. Future research highlighted here may have the potential, especially in combination approaches, to repair challenging interproximal soft and hard tissue deficiencies.

Abstract
BACKGROUND Aim of this systematic review (SR) of randomized controlled trials (RCTs) was to evaluate effect of different flap designs and graft materials for root coverage, in terms of aesthetics, patient satisfaction and self-reported morbidity (post-operative pain/discomfort). MATERIAL AND METHODS A comprehensive literature search was performed. A mixed-modelling approach to network meta-analysis was utilized to formulate direct and indirect comparisons among treatments for Root Coverage Esthetic Score (RES), with its individual components, and for subjective patient-reported satisfaction and post-operative pain/discomfort (visual analogue scale (VAS) of 100). RESULTS Twenty-six RCTs with a total of 867 treated patients (1708 recessions) were included. Coronally Advanced Flap (CAF) + Connective Tissue Graft (CTG) (0.74 (95% CI [0.24, 1.26], p = .005)), Tunnel (TUN) + CTG (0.84 (95% CI [0.15, 1.53]), p = .01) and CAF + Graft substitutes (GS) (0.55 (95% CI [0.006, 1.094], p = .04)) were significantly associated with higher RES than CAF. No significant difference between CAF + CTG and TUN + CTG was detected (0.09 (95% CI [-0.54, 0.72], p = .77)). Addition of CTG resulted in less natural tissue texture (-0.21 (95% CI [-0.34, -0.08]), p = .003) and gingival colour (-0.06 (95% CI [-0.12, -0.03], p = .03)) than CAF. CTG techniques were associated with increased morbidity. CONCLUSIONS Connective tissue graft procedures showed highest overall aesthetic performance for root coverage, although graft integration might impair soft tissue colour and appearance. Additionally, CTG-based techniques were also correlated with a greater patient satisfaction and morbidity.

Abstract
BACKGROUND The literature lacks long-term evidence regarding outcomes of the coronally advanced tunnel flap (TUN) combined with connective tissue graft (CTG) when compared to the trapezoidal coronally advanced flap (CAF) and CTG combination. This study presents 2-year results of a randomized clinical trial comparing CTG combined with either CAF or TUN in the treatment of single maxillary gingival recession (GR) defects. METHODS Thirty-nine patients, each contributing a single Miller Class I or II GR defect, were treated by CAF+CTG (control; n = 19) or TUN+CTG (test; n = 20) and completed the 2-year follow up. Clinical, patient centered, and esthetic evaluations were performed and differences among groups were analyzed. RESULTS At 2 years, mean root coverage for control and test group was 89.5% ± 14.6% and 87.7% ± 18.4%, respectively (P = 0.5). The corresponding complete root coverage prevalence was 68.4% and 50% (P = 0.4). Dentin hypersensitivity significantly decreased for both groups. The two groups showed improvement in esthetics, as assessed by both professionals and patients, without significant intergroup differences (P > 0.5). TUN+CTG sites were much more likely to present improvement in root coverage between 6 months and 2 years, exhibiting creeping attachment of 0.7 ± 0.6 mm. CONCLUSIONS At 2 years of follow up, both CAF+CTG and TUN+CTG resulted in significant clinical and esthetic improvements and provided similar results in the treatment of single maxillary GRs.

Abstract
PURPOSE The objective of this systematic review was to evaluate the risk of development of gingival recession (GR) as a result of the combined orthodontic-orthognathic approach. MATERIALS AND METHODS The PubMed, Google Scholar, ClinicalTrials.gov, and Cochrane Library databases were searched. Included articles mentioned gingival parameters in their materials and methods sections; specifically, they evaluated GR, which was measured before and after the surgical procedure. Study parameters such as methodology, evaluation period, sample characteristics, and follow-up were extracted by 2 authors independently. RESULTS In total, 133 relevant articles were identified from the databases; after screening and full-text analysis, 9 studies were included in this systematic review. Meta-analysis could not be conducted because of considerable heterogeneity in methods. The incidence of GR in the range of 0.5 to 3.0 mm as a significant clinical finding after orthognathic surgery showed statistically significant differences in all included articles. Among patients with GR, the mean age was 23.0 to 29.5 years and the mandibular incisors were the most common site. However, no case of recession greater than 3.0 mm was associated with surgery. CONCLUSIONS On the basis of the findings of this review, GR of approximately 0.5 to 3.0 mm is a common finding after the combined orthodontic-orthognathic approach. Although periodontal damage up to 3 mm can be observed as an isolated finding in mainly the incisors, true recession is not associated with orthognathic surgery in general.

Clinical efficacy of xenogeneic and allogeneic 3D matrix in the management of gingival recession: a systematic review and meta-analysis. Clin Oral Investig 2020; 24:2229-2245.

Abstract
OBJECTIVE A systematic review and meta-analysis was thus conducted to answer the following focused question based on PICO strategy: Is there any 3D matrix biomaterial used for root coverage of human Miller class I and II defects equivalent with the connective tissue graft in localized defects of at least 2 mm and 3 mm? MATERIAL AND METHODS The search on electronic database included MEDLINE, Cochrane Central Register of Controlled Trials, Clinical Trials.gov, Web of Science, and New Zealand/Australian Clinical Trials. Only randomized clinical trials (RCTs) that compared connective tissue graft (CTG) with at least one 3D matrix alone for root coverage in Class I and II Miller localized defects of at least 2 mm, with at least 6 months follow-up, were included in this systematic review. RESULTS A total of 14 studies were included for meta-analysis (12 compared CTG with acellular dermal matrix allograft and 2 compared CTG with Xenogenic Collagen Matrix). Relative root coverage showed no significant difference among the materials, for either 2 or 3 mm minimal recessions. For keratinized tissue width, on 2 mm recessions, CTG showed superiority above other biomaterials, but on 3 mm recessions, it seemed to have the same results. The percentage of recessions with complete root coverage for both 2 and 3 mm recessions showed similar results for all biomaterials. CONCLUSIONS With their limits, the present data concluded that CTG, acellular dermal matrix allograft, and xenogenic collagen matrix provided similar results for root coverage. CLINICAL RELEVANCE To know if there is a 3D matrix with equivalent predictable results for root coverage, that we could avoid the morbidity of the connective tissue graft for these cases.

MATERIALS 2019; 12:ma12172790. [PMID: 31480232 PMCID: PMC6747963 DOI: 10.3390/ma12172790] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2019] [Revised: 08/24/2019] [Accepted: 08/27/2019] [Indexed: 12/12/2022]
Abstract
Background: The systematic review was designed to answer the following focused question: Are enamel matrix derivatives able to improve the quantity of keratinized tissue (KT) around natural dentition in patients with recessions defects after their treatment with periodontal plastic procedures? Methods: Only Randomized Clinical Trials (RCT) in English language evaluating root coverage procedures in combination with enamel matrix derivatives (commercially known as Emdogain®—EMD), with at least 10 subjects and a minimum duration of six months, were included. The search was applied to PUBMED and SCOPUS and it consists of a combination of MeSH terms and free text words (from January 2000 to June 2019). Risk of bias in individual studies and across studies was also evaluated. Results: After the full text analysis and the exclusion of further 18 articles, 12 articles were finally included. In total 639 recessions were treated (334 tests and 305 control). The recessions defects were classified according to the classification of Miller (Class I, II, III, IV). Only one trial included Miller Class III recessions (7 in total). Enamel matrix derivatives were applied in conjunction with Coronally Advanced Flap (CAF), Coronally Advanced Flap + Sub Epithelial Connective Tissue Graft (CAF + CTG), Semilunar Flap (SF). For the group CAF vs CAF + EMD the mean difference between the keratinized tissue gain in the two procedures was 0.40 mm (95% Confindence Interval Lower/Upper: 0.014–0.81) (p < 0.058); for the comparison CAF + CTG + EMD vs. CAF + CTG the mean difference between the two groups resulted in −0.06 mm (95% Confindence Interval Lower Upper −0.45 to 0.33) (p = 0.7603). Discussion: Randomized clinical trials included medium-low quality evidence. The application of Enamel Matrix Derivatives to surgical procedures aimed to cover gingival recessions does not add robust clinical benefit to conventional plastic procedure alone.

Abstract
The stability of root coverage outcomes has gained a great deal of interest. However, insufficient evidence is available, mainly due to limited direct comparisons among different techniques and the small sample size among clinical trials. Therefore, the aim of this study was to propose a mixed-models network meta-analysis (NMA) that includes the novelty of assessing time on root coverage outcomes while simultaneously comparing different surgical approaches. A literature search was performed by 2 individual reviewers to identify randomized clinical trials (RCTs) reporting the outcomes of root coverage procedures of at least 2 time points to estimate the slopes of different treatment approaches. The primary outcomes were the changes in slopes for recession depth (REC), keratinized tissue width (KTW), and clinical attachment level. Sixty RCTs with a total of 2,554 gingival recessions (1,864 patients) were included in the NMA. Connective tissue graft (CTG) and enamel matrix derivative (EMD) approaches provided superior initial REC reduction compared to flap advancement alone. However, only CTG-based procedures were effective in maintaining the stability of the gingival margin over time, while EMD, acellular dermal matrix, collagen matrix, and flap alone showed a similar tendency for gingival recession recurrence. Baseline REC and KTW at the earliest postoperative recall were predictors for the stability of the gingival margin. In addition, a geographic center effect on the treatment slopes was observed for REC and KTW. While limitations of the present linear mixed-modeling approach should be considered as it refers to estimation and comparison of time slopes based on an examined while linear framework, the designed NMA showed to be an effective tool for the simultaneous comparison of multiple treatment approaches while taking into account the critical element of time.

Abstract
AIM To evaluate the long-term outcomes of Acellular Dermal Matrix (ADM) with Coronally Advanced Flap (CAF) or Tunnel technique (TUN) in the treatment of multiple adjacent gingival recessions (MAGRs). MATERIAL AND METHODS Nineteen of the original 24 patients contributing to a total number of 33 sites for CAF and 34 for TUN were available for the 12 years follow-up examination. Recession depth, mean root coverage (mRC), keratinized tissue width (KTW), gingival thickness (GT) were evaluated and compared with baseline values and 6-months results. Regression analysis was performed to identify factors related to the stability of the gingival margin. RESULTS A highly significant drop in mRC was observed for both groups from the 6 months timepoint to the 12 years recall (p < .001). While there were no statistically significant differences between the two groups in terms of Clinical Attachment Level (CAL), KTW, GT changes and Root Coverage Esthetic Score at each timepoint (p > .05). KTW ≥ 2 mm and GT ≥ 1.2 mm at 6-months were two predictors for stability of the gingival margin (p = .03 and p = .01, respectively). CONCLUSIONS A significant relapse of the gingival margin of MAGRs treated with CAF or TUN + ADM was observed after 12 years.

Abstract
AIM To compare outcomes of modified coronally advanced tunnel technique (MCAT) combined with either collagen matrix (CM) or subepithelial connective tissue graft (SCTG) in the treatment of Miller class I and II multiple gingival recessions in the mandible. MATERIALS AND METHODS The study encompassed 91 recessions in 29 patients for whom MCAT was combined with CM on one side of the mandible and SCTG on the contralateral one. The following clinical parameters were measured: gingival recession height (GR) and width (RW), probing depth (PD), clinical attachment level (CAL), width of keratinized tissue (KT), gingival thickness (GT), mean (MRC) and complete root coverage (CRC) and Root Coverage Esthetic Score (RES). RESULTS The MRC proportions on the CM- and SCTG-treated sides were 53.20% and 83.10%, respectively. CRC was achieved in 9 out of 45 (20%) gingival defects treated with CM and 31 out of 46 (67%) treated with SCTG. There were statistically significant differences in MRC, CRC, GR, RW, KT, GT and RES between CM- and CTG-treated sides. CONCLUSIONS Modified coronally advanced tunnel technique leads to reduction in gingival recession both when combined CM and SCTG, of which the latter is more efficient as far as root coverage and aesthetic parameters are concerned.

Abstract
BACKGROUND Gingival recession is defined as the oral exposure of the root surface due to a displacement of the gingival margin apical to the cemento-enamel junction and it is regularly linked to the deterioration of dental aesthetics. Successful treatment of recession-type defects is based on the use of predictable root coverage periodontal plastic surgery (RCPPS) procedures. This review is an update of the original version that was published in 2009. OBJECTIVES To evaluate the efficacy of different root coverage procedures in the treatment of single and multiple recession-type defects. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 15 January 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 12) in the Cochrane Library (searched 15 January 2018), MEDLINE Ovid (1946 to 15 January 2018), and Embase Ovid (1980 to 15 January 2018). The US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials (15 January 2018). No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) only of at least 6 months' duration evaluating recession areas (Miller's Class I or II ≥ 3 mm) and treated by means of RCPPS procedures. DATA COLLECTION AND ANALYSIS Screening of eligible studies, data extraction and risk of bias assessment were conducted independently and in duplicate. Authors were contacted for any missing information. We expressed results as random-effects models using mean differences (MD) for continuous outcomes and odds ratios (OR) for dichotomous outcomes with 95% confidence intervals (CI). We used GRADE methods to assess the quality of the body of evidence of our main comparisons. MAIN RESULTS We included 48 RCTs in the review. Of these, we assessed one as at low risk of bias, 12 as at high risk of bias and 35 as at unclear risk of bias. The results indicated a greater reduction in gingival recession for subepithelial connective tissue grafts (SCTG) + coronally advanced flap (CAF) compared to guided tissue regeneration with resorbable membranes (GTR rm) + CAF (MD -0.37 mm; 95% CI -0.60 to -0.13, P = 0.002; 3 studies; 98 participants; low-quality evidence). There was insufficient evidence of a difference in gingival recession reduction between acellular dermal matrix grafts (ADMG) + CAF and SCTG + CAF or between enamel matrix protein (EMP) + CAF and SCTG + CAF. Regarding clinical attachment level changes, GTR rm + CAF promoted additional gains compared to SCTG + CAF (MD 0.35; 95% CI 0.06 to 0.63, P = 0.02; 3 studies; 98 participants; low-quality evidence) but there was insufficient evidence of a difference between ADMG + CAF and SCTG + CAF or between EMP + CAF and SCTG + CAF. Greater gains in the keratinized tissue were found for SCTG + CAF when compared to EMP + CAF (MD -1.06 mm; 95% CI -1.36 to -0.76, P < 0.00001; 2 studies; 62 participants; low-quality evidence), and SCTG + CAF when compared to GTR rm + CAF (MD -1.77 mm; 95% CI -2.66 to -0.89, P < 0.0001; 3 studies; 98 participants; very low-quality evidence). There was insufficient evidence of a difference in keratinized tissue gain between ADMG + CAF and SCTG + CAF. Few data exist on aesthetic condition change related to patients' opinion and patients' preference for a specific procedure. AUTHORS' CONCLUSIONS Subepithelial connective tissue grafts, coronally advanced flap alone or associated with other biomaterial and guided tissue regeneration may be used as root coverage procedures for treating localised or multiple recession-type defects. The available evidence base indicates that in cases where both root coverage and gain in the width of keratinized tissue are expected, the use of subepithelial connective tissue grafts shows a slight improvement in outcome. There is also some weak evidence suggesting that acellular dermal matrix grafts appear as the soft tissue substitute that may provide the most similar outcomes to those achieved by subepithelial connective tissue grafts. RCTs are necessary to identify possible factors associated with the prognosis of each RCPPS procedure. The potential impact of bias on these outcomes is unclear.

Abstract
Diverse clinical advancements, together with some relevant technical innovations, have led to an increase in popularity of tunneling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession-type defects, tunneling flap procedures may now be applied successfully in a variety of clinical situations in which augmentation of the soft tissues is indicated in the esthetic zone. Potential clinical scenarios include surgical thickening of thin buccal gingiva or peri-implant mucosa, alveolar ridge/socket preservation and implant second-stage surgery, as well as soft-tissue ridge augmentation or pontic site development. In this way, tunneling flap procedures developed from a technique, originally merely intended for surgical root coverage, into a capacious surgical conception in plastic periodontal and implant surgery. The purpose of this article is to provide a comprehensive overview on tunneling flap procedures, to introduce the successive development of the approach along with underlying ideas on surgical wound healing and to present contemporary clinical scenarios in step-by-step photograph-illustrated sequences, which aim to provide clinicians with guidance to help them integrate tunneling flap procedures into their daily clinical routine.
