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.

Efficacy of Tunnel Technique (TUN) versus Coronally Advanced Flap (CAF) in the Management of Multiple Gingival Recession Defects: A Meta-Analysis. Int J Dent 2023; 2023:8671484. [PMID: 37063452 PMCID: PMC10101741 DOI: 10.1155/2023/8671484] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 10/06/2022] [Accepted: 03/22/2023] [Indexed: 04/18/2023] Open
Abstract
Objective We systematically assessed the efficacy of tunnel technique (TUN) vs. coronally advanced flap (CAF) in the management of multiple gingival recession defects in adults. Methods Five databases were searched until September 2021 for randomized controlled trials (RCTs) assessing TUN vs. CAF; grafts of interest were acellular dermal matrix (ADM) and connective tissue graft (CTG). Primary outcomes were root coverage (RC) and complete root coverage (CRC). Secondary outcomes were clinical attachment level (CAL), keratinized tissue width (KTW), probing depth (PD), and recession coverage (REC). Effect measures were risk ratio (RR) or mean difference (MD) with their confidence intervals (95% CI). Inverse variance methods and random-effects model meta-analyses were used. Subgroup analyses by the type of graft were performed. Quality of evidence was assessed using GRADE methodology. Results Five RCTs (n = 173) were included, with a follow-up of 6 months for all outcomes. In comparison to CAF, TUN did not significantly reduce CRC (RR 0.65; 95% CI 0.002-176.7; p = 0.51) and did not increase RC (MD 0.99%; 95% CI -6.7 to 8.6; p = 0.80). In comparison to CAF, TUN showed no significant reduction of secondary outcomes. Subgroup analyses by type of graft showed no differences in comparison to primary analyses for primary and secondary outcomes. Three RCTs had a high risk of bias, and five RCTs had very low quality of evidence for all outcomes. Conclusions In adults with gingival recessions, TUN had similar primary and secondary outcomes in comparison with CAF. Subgroup analyses by the type of graft did not affect main conclusions. More RCTs with better design are needed to further characterize the effects of TUN vs. CAF in the treatment of multiple gingival recession defects.

Abstract
OBJECTIVES There are few studies comparing xenogeneic acellular dermal matrixes (XDMs) with connective tissue graft (CTG) to treat single gingival recession (GR). The present study involved a reanalysis of previous studies and comparison of CTG or XDM to treat single RT1/GR. MATERIALS AND METHODS Fifty patients from three previous randomized clinical trials treated either by CTG (n = 25) or XDM (n = 25) were evaluated after 6-month. Clinical, patient-centered, and esthetic parameters were assessed. Pearson's correlation and regression analyses were also performed. RESULTS Greater recession reduction (RecRed), percentage of root coverage (%RC), and complete root coverage (CRC) were observed in the CTG group (p ≤ 0.02). Gingival thickness (GT) and keratinized tissue width (KTW) gains were higher in the CTG group. The CTG group showed better esthetic at 6-month. Logistic analyses reported that GT([OR] = 1.6473 ) and papilla height (PH) (OR = 8.20) are predictors of CRC. GT*XDM interaction was a negative predictor of CRC (OR = 7.105-5 ). GT at baseline acted as a predictor of RecRed in both groups (p = 0.03). The XDM graft impacted RecRed and %RC negatively. Baseline PH was a predictor of %RC for both grafts. CONCLUSION CTG was superior for treating RT1/GR, providing better root coverage outcomes and tissue gains over time. GT, PH, and graft type were classified as predictors of CRC. CLINICAL SIGNIFICANCE CTG presented better outcomes to treat single RT1 gingival recession when compared to the XDM.

Abstract
INTRODUCTION Gingival recession is one of the most common mucogingival deformities requiring surgical correction. The American Academy of Periodontology Regeneration Workshop recommended connective tissue graft (CTG) combined with coronally advanced flap (CAF) for the treatment of Miller Class I and II single-tooth gingival recession. The disadvantages of harvesting autogenous tissue include postoperative bleeding, pain and discomfort at the donor site, restricted tissue supply, increased morbidity and prolonged operative times. Acellular dermal matrix (ADM) contains undamaged collagen and elastin matrices that can be used as a substitute for CTG during root coverage procedures. However, the use of ADM is still controversial. The objective of this split-mouth; randomised, controlled, clinical study is to evaluate the long-term effects of ADM graft (ADMG) combined with CAF on root coverage, aesthetics and patient satisfaction for the treatment of single gingival recession with thin gingival phenotype. METHODS AND ANALYSIS Forty participants with bilateral Miller Class I/II gingival recession will be randomised to receive an ADMG on one side and CTG on the contralateral side, combined with CAF. Gingival recession depth, gingival recession width and keratinised tissue width will be measured at baseline, 2 weeks and 1, 3, 6, 12 and 24 months. Mean root coverage, complete root coverage, root coverage aesthetic score, colour change (∆E) and patient satisfaction will be assessed during follow-up visits. ETHICS AND DISSEMINATION The present study has received approval from the Ethics Committee of Peking University School and Hospital of Stomatology (PKUSSIRB-202054029). Data of this study will be registered with the International Clinical Trials Registry Platform. Additionally, we will disseminate the results through scientific journal.

Abstract
OBJECTIVE To evaluate the efficacy of tunnel technique (TUN) in treatment of teeth with adjacent gingival regression (GR) combined with noncarious cervical lesions (NCCL). METHODS We collected data from 21 patients (79 teeth) undergoing TUN surgery for GR combined with NCCL. According to GR depth (GRD) and lesion depth (LD) of NCCL, the teeth were divided into group 1 with GRD≤3 mm and LD≤1 mm; group 2 with GRD≤3 mm and LD>1mm; group 3 with GRD>3 mm and LD≤1 mm; and group 4 with GRD>3 mm and LD>1 mm. The mean root coverage (MRC) rate, complete root coverage (CRC) rate, keratinized gingival width, and keratinized gingival thickness were compared among the 4 groups after TUN surgery. RESULTS The keratinized gingival width and thickness were significantly improved after the surgery in the 4 groups. When the GRD was below 3 mm, the MRC was not significantly different between group 1 and group 2 (8.55% vs 95.45%, P>0.05); When the GRD was beyond 3 mm, the MRC and CRC rates were both decreased in group 3 and group 4, especially in group 4, where the CRC rate (25%) was significantly lower than those in the other 3 groups (P < 0.01). CONCLUSION In patients with GR combined with NCCL, TUN surgery can obviously improve keratinized gingival width and thickness. GRD has a greater effect on the outcome of root coverage than LD, suggesting that NCCL restoration before TUN surgery may not be necessary. Both GRD and LD should be considered in the evaluation of the clinical efficacy of TUN surgery.

Abstract
BACKGROUND Xenogeneic matrices (XMs) have been increasingly used for root coverage procedures. This study compared the use of two types of XM (collagen matrix [CM] and xenogeneic acellular dermal matrix [XDM]) associated with the coronally advanced flap technique (CAF) to treat single gingival recessions. METHODS Seventy-five patients presenting single RT1 gingival recession were treated by CAF (control group, n = 25), CAF+CM (test group 1, n = 25), or CAF+XDM (test group 2, n = 25) and completed 6-month follow-up. Clinical, patient-centered, and esthetic assessments were performed and intra- and intergroup differences were analyzed. RESULTS At 6 months, the mean recession reduction for CAF, CAF+CM, and CAF+XDM was 2.4 ± 0.8 mm, 2.4 ± 0.9 mm and 2.1 ± 0.8 mm, respectively (P > 0.05). The corresponding mean percentage of root coverage was 78.9% ± 26.2% for CAF, 78.0% ± 28.5% for CAF+CM, and 65.6% ± 26.9% for CAF+XDM (P > 0.05). Dentin hypersensitivity and esthetic conditions showed significantly improvements in all groups. Test groups presented significant gains in gingival thickness (GT; CAF+CM: 0.4 ± 0.3 mm; CAF+XDM: 0.4 ± 0.2 mm) compared to the control group (CAF: 0.0 ± 0.1 mm; P < 0.05). CONCLUSION The CAF, CAF+CM, and CAF+XDM treatments each provided similar results in the treatment of single gingival recessions. The addition of either CM or XDM to CAF increases the GT.

Abstract
AIM To compare the outcomes of modified coronally advanced flap (mCAF) combined with either xenogeneic dermal matrix (XDM) or connective tissue graft (CTG) for the treatment of multiple adjacent gingival recessions (MAGRs). MATERIALS AND METHODS Forty-two patients, in whom 130 maxillary (MAGRs) of type (RT1) were found, were randomly allocated to the two groups. Clinical, esthetic, and patient-centered outcomes were evaluated at baseline, 6, and 12 months post-treatment. RESULT Group CAF+ CTG exhibited a higher mean root coverage value (mRC) (91.79%) (primary outcome variable) than group CAF+XDM (80.19%) without statistically significant difference at 12 months (p=0.06). The control group also had significantly higher percentage of teeth in which complete root coverage (CRC) and mean gain of gingival thickness (GT) were achieved, than the test group (p<0.05). With respect to patient-centered outcomes, patients of the test group reported having experienced significantly less pain than those of the control group until 7 days (p<0.05). Both surgical approaches were capable of significantly decreasing dentin hypersensitivity (p<0.05). No difference between groups was found in the esthetic score analysis (p>0.05). Mean surgical time was lower in the test group (p<0.05). CONCLUSION The two treatments showed similar mRC. However, CAF+CTG was superior to CAF+XDM in providing CRC and in gaining GT. CAF+XDM demonstrated advantages over CAF+CTG with regard to patient morbidity and surgical time. CLINICAL RELEVANCE Application of XDM provided a better patient experience and shortened the time to recovery after coronally advanced flaps for coverage of multiple adjacent recessions. However, CTG resulted in improved percentages of complete root coverage. TRIAL REGISTRATION Brazilian Clinical Trials Registry (REBEC) number: RBR-974c9j.

Abstract
OBJECTIVES This study aimed to compare xenogeneic dermal matrix (XDM) to connective tissue graft (CTG) associated with coronally advanced flap (CAF) in treating Miller's class I and II (RT1) multiple gingival recession in a split-mouth randomized clinical trial. MATERIALS AND METHODS Fifteen patients with bilateral Miller's class I and II multiple recessions were selected. The patient's side receiving each treatment was randomly allocated to receive XDM or CTG. The clinical parameters were measured at baseline and 6 months of follow-up. RESULTS At 6 months, no significant difference in the root coverage (RC) (95.28 ± 6.89% for CTG and 92.68 ± 7.35% for XDM) and the keratinized tissue (KT) gain (0.91 ± 0.46 mm for CTG and 0.74 ± 0.39 mm for XDM) was observed between groups (p > 0.05). The CTG group presented higher complete root coverage (CRC) than XDM (60% and 33%, respectively) (p = 0.045). Multiple logistic regression indicated that the XDM (p = 0.01) and the XDM and KT interaction (p = 0.02) negatively interfered in the CRC. A 1-mm increase in the baseline KT when using XDM increases almost 6 times the chance of achieving CRC, and XDM reached a similar CRC probability to CTG when the receptor area presented at least 2 mm of KT. CONCLUSIONS Both treatments were effective for treating multiple gingival recession; similar KT gain, GR reduction, and RC were obtained for CTG and XDM, while CTG promoted higher CRC than XDM. Moreover, the amount of KT at baseline was determinant for CRC when treating multiple gingival recession with XDM. CLINICAL RELEVANCE XDM produces limited CRC in sites with a reduced amount of KT.

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.

J ESTHET RESTOR DENT 2020; 32:681-690. [PMID: 32706184 DOI: 10.1111/jerd.12624] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 06/16/2020] [Accepted: 06/19/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To assess the clinical efficacy and esthetic outcome of porcine-derived dermal collagen matrix in comparison with connective tissue graft in the treatment of multiple adjacent gingival recessions (MAGR), 6 and 12 months after the surgery. MATERIALS AND METHODS Twenty patients with bilateral type I MAGR were treated randomly with porcine-derived dermal collagen matrix (test site) or connective tissue graft (control site) in combination with a modified coronally advanced tunnel technique. The primary objectives were to evaluate the mean and complete root coverage. The secondary objectives were to assess keratinized tissue width, gingival thickness gain, and root coverage esthetic score. RESULTS Six and 12 months postoperatively, both groups achieved significant improvements in all clinical parameters compared to baseline, with no statistically significant differences between the groups. Mean root coverage change (Δ12m - 6 m) was statistically significant between the groups in favor of connective tissue graft, and twice as many patients exhibited a complete coverage of all recessions in the control group than the test group. CONCLUSION The porcine-derived dermal collagen matrix combined with a modified coronally advanced tunnel technique resulted in satisfactory clinical and esthetic outcomes, which were similar to connective tissue graft. CLINICAL SIGNIFICANCE Porcine-derived dermal collagen matrix (XDM) may be proposed as a substitute for connective tissue graft in multiple adjacent recession treatment due to successful root coverage, a significant increase of gingival thickness, and high esthetic outcomes. The clinical benefits for the use of XDM could be: (a) second surgical wound avoidance, (b) patient discomfort decrease, and (c) lower complications' rate.

A 3-Year Prospective Study on a Porcine-Derived Acellular Collagen Matrix to Re-Establish Convexity at the Buccal Aspect of Single Implants in the Molar Area: A Volumetric Analysis. J Clin Med 2020; 9:jcm9051568. [PMID: 32455863 PMCID: PMC7290720 DOI: 10.3390/jcm9051568] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 05/10/2020] [Accepted: 05/20/2020] [Indexed: 01/07/2023] Open
Abstract
Background: Xenogeneic soft tissue substitutes are currently being investigated as an alternative to subepithelial connective tissue grafts (CTG) with the intention to avoid postoperative morbidity associated with autologous grafting. The aim of the present study was to volumetrically evaluate the effectiveness and mid-long-term stability of a porcine-derived collagen matrix (PDCM) (Mucoderm®, Botiss gmbh, Berlin, Germany) in increasing soft tissue volume at the buccal aspect of molar implant sites. Methods: Periodontally healthy non-smoking patients with a single tooth gap in the molar area were selected for a prospective case series. All sites had a bucco-oral bone dimension of at least 8 mm and demonstrated a horizontal alveolar defect. A wide diameter implant was placed under the elevated buccal flap and a PDCM was applied. The primary outcome was the linear increase in buccal soft tissue profile (BSP) within a well-defined area of interest. This was performed with designated software (SMOP; Swissmeda AG, Zurich, Switzerland) on the basis of superimposed digitalized study casts taken before surgery (T0), immediately after surgery (T1), at three months (T2), one year (T3) and three years (T4). Secondary outcomes were alveolar process deficiency and clinical parameters. Results: Fourteen out of 15 treated patients attended the three-year re-assessment (four females; mean age 51.4 years). Mean linear increase in BSP at T1 was 1.53 mm (p = 0.001). The PDCM showed substantial resorption at T2 (1.02 mm or 66.7%) (p = 0.001). Thereafter, a 0.66 mm volume gain was observed (p = 0.030), possibly due to the installation of a permanent crown displacing the soft tissues to the buccal aspect. This resulted in a linear increase in BSP of 1.17 mm (76.5%) at T4. Alveolar process deficiency significantly reduced over time (p = 0.004). However, 50% of patients still demonstrated a slight (6/14) or obvious (1/14) alveolar process deficiency at study termination. Implants demonstrated healthy clinical conditions. Conclusions: The PDCM demonstrated marked resorption during the early stages of healing. Due to the matrix thickening the tissues, and the permanent crown displacing the tissues, 76.5% of the initial increase in BSP could be maintained over a three-year period. Half of the patients failed to show perfect soft tissue convexity at the buccal aspect.

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
Mucogingival surgery is a general term for periodontal surgeries that correct aberrant periodontal soft tissues. Conventional mucogingival surgeries with pedicle flap or autologous soft tissue graft for treatment of gingival recession and insufficient keratinized tissues are always related to disadvantages such as need for a second surgery site, limited supplies, and complaints for postoperative discomfort. In this regard, research and application of soft tissue substitutes have gained increasing attention. Various kinds of soft tissue substitutes, including acellular dermal matrix and xenogeneic collagen matrix, have been developed and applied to clinical treatment. This review aims to summarize advances in research of the characteristics and clinical effectiveness of several soft tissue substitutes and provide references for clinical application.

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.
