Huang Y, Ouyang X, Liu B, Liu J, Liu W, Xie Y. Long-term success and influencing factors of regenerative surgery for intra-bony defects: A retrospective cohort study. J Periodontol 2024. [PMID: 38937867 DOI: 10.1002/jper.23-0701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 05/25/2024] [Accepted: 05/28/2024] [Indexed: 06/29/2024]
Abstract
BACKGROUND The composite outcome measure (COM) more comprehensively assesses the clinical efficacy of regenerative surgery than a single probing measurement. We aimed to assess long-term success defined by the COM (clinical attachment level [CAL] gain of ≥3 mm and postsurgery probing pocket depth [PPD] ≤ 4 mm) and influencing factors of regenerative surgery using bone substitutes and resorbable collagen membrane (RM) for intra-bony defects (IBDs). METHODS We retrospectively collected data from patients who underwent regenerative surgery using deproteinized bovine bone mineral (DBBM) and RM for IBDs. CAL and PPD values were compared at baseline (preoperative), 1 year (short-term), and at the last follow-up (5-10 years). Multivariate logistic regressions were performed to identify factors influencing COM-based long-term success. RESULTS Eighty-one defects in 75 teeth of 33 patients who completed follow-up (6.5 ± 1.4 years) were included. One tooth was lost. All defects with complete follow-up exhibited long-term average CAL gain (3.00 ± 2.00 mm, 95% confidence interval [CI]: 2.56-3.44 mm, p < 0.001) and PPD reduction (2.06 ± 1.91 mm, 95% CI: 1.64-2.49 mm, p < 0.001). Long-term success was achieved in 38.8% of IBDs. CAL and PPD values were comparable between 1 year and the last follow-up. Logistic regression analyses revealed that male sex (odds ratio [OR] = 0.23, 95% CI: 0.07-0.75) and bleeding on probing (BOP) during supportive periodontal therapy (OR = 0.96, 95% CI: 0.94-0.99) were risk factors for long-term success. CONCLUSIONS Regenerative surgery with DBBM and RM for IBDs can achieve some degree of long-term success defined by COM. However, within this study's limitations, male sex and higher BOP incidence postoperatively are negatively associated with optimal long-term success. CLINICAL TRIAL NUMBER ChiCTR2300069016.

Evid Based Dent 2024:10.1038/s41432-024-01024-4. [PMID: 38867104 DOI: 10.1038/s41432-024-01024-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Accepted: 05/03/2024] [Indexed: 06/14/2024]
Abstract
OBJECTIVES The aim of this systematic review was to comprehensively explore the current trends and therapeutic approaches in which an operating microscope (OM) is used in periodontics and dental implant surgeries. MATERIALS AND METHODS A systematic search strategy was built to detect studies including various surgical techniques performed under an OM. PubMed, EMBASE, and SCOPUS databases were searched. No limitations in terms of time and language were applied. The data regarding the study design, type of procedure, treatment groups, and surgical outcomes were collected and analyzed descriptively. In addition, a bibliometric analysis was performed concerning the co-authorship and keyword co-occurrence network. RESULTS Out of 1985 articles, finally, 55 met the inclusion criteria. Current periodontal and implant microsurgery trends consist of: periodontal therapy, dental implant microsurgery, soft tissue grafting and periodontal plastic surgery, bone augmentation, ridge preservation, and ortho-perio microsurgery. The bibliometric analysis revealed "guided tissue regeneration", "periodontal regeneration" and "root coverage" being the most repeated keywords (landmark nodes). 132 authors within 29 clusters were identified, publishing within the frameworks of "periodontal and implant microsurgery". CONCLUSION Within its limitations, this systematic review provides an overview of the latest trends in periodontal and implant microsurgery when considering the use of an OM as the magnification tool. Also, it discusses the reported success and outcomes of the mentioned procedures.

Ogawa Y, Yoshikawa K, Ishikawa T, Saito A, Imamura K. Double-sided entire papilla preservation technique in the combination periodontal regenerative therapy: A case report. Clin Adv Periodontics 2024; 14:100-107. [PMID: 37434397 DOI: 10.1002/cap.10258] [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: 03/15/2023] [Revised: 06/10/2023] [Accepted: 07/04/2023] [Indexed: 07/13/2023]
Abstract
BACKGROUND With the entire papilla preservation (EPP) technique, it is possible to perform regenerative therapy without incisions in the interdental papilla and to reduce the risk of papillary rupture. However, one limitation of the EPP is the sole access from the buccal side. Here, we present a case of periodontitis treated by the combination regenerative therapy employing the Double-sided (buccal-palatal) EPP (DEPP) technique, which adds a palatal vertical incision to the EPP. METHODS A patient with 1-2 wall intrabony defects received the regenerative therapy using recombinant human fibroblast growth factor (rhFGF)-2 and carbonate apatite (CO3Ap). Using the DEPP technique, vertical incisions at buccal and palatal aspects were placed to gain adequate access to the 1-2 wall intrabony defects between #11 and #12 without incision in the interdental papilla. After debridement, rhFGF-2 and CO3Ap were applied to the defect. Periodontal clinical parameters and radiographic images were evaluated at the first visit, following initial periodontal therapy (baseline), 6, 9, and 12 months postoperatively. RESULTS Wound healing was uneventful. Scarring of the incision lines was minimal. At 12 months postoperatively, probing depth reduction was 4 mm, clinical attachment gain was 4 mm, and gingival recession was not observed. An improvement in radiopacity in the previous bone defect was observed. CONCLUSION The DEPP is an innovative technique that allows approaching from both the buccal and palatal sides while ensuring flap extensibility without compromising the interdental papilla. This report suggests that the combination of regenerative therapy with the DEPP may be promising in the treatment of intrabony defects. KEY POINTS Why is this case new information? The DEPP allows a direct visual approach to a 1-2 wall intrabony defect extending from the buccal to palatal sides, and increases flap extensibility, without compromising the papilla. What are the keys to the successful management of this case? Assessment of three-dimensional bone defect morphology is required. Computed tomography images are very useful. The flap elevation just under the interdental papilla should be carefully performed with a small excavator to avoid damage to the interdental papilla. What are the primary limitations to success in this case? Despite the addition of a palatal incision, it was not possible to obtain complete flexibility of the palatal gingiva. Caution must be taken in a case in which the distance between the interdental papilla is narrow. Even if the interdental papilla is ruptured during the operation, recovery is possible by continuing the operation and suturing the rupture at the end.

Minimally invasive periodontal regeneration with the buccal approach: a systematic review and meta-analysis of clinical studies. Evid Based Dent 2024; 25:54. [PMID: 38182662 DOI: 10.1038/s41432-023-00964-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 11/17/2023] [Accepted: 11/28/2023] [Indexed: 01/07/2024]
Abstract
OBJECTIVE The aim of this study was to investigate clinical periodontal parameters after treatment using the Minimally Invasive Surgical Technique (MIST), Modified Minimally Invasive Surgical Technique (M-MIST), and/or any technique for papilla preservation, such as Entire Papilla Preservation (EPP), modified-papilla preservation technique (M-PPT), or simplified-papilla preservation technique (SPPT). METHODS The focus question was "For patients with periodontal intrabony defects (P), what is the best minimally invasive regenerative approach (I), comparing MIST, M-MIST, and papilla preservation techniques' outcomes (C) to improve PD, CAL, GR, and periodontal stability (O)?" An online search was conducted on PubMed, Cochrane Library, and Embase. Only randomized clinical trials and case series with a minimum of 10 enrolled patients were included. The risk of bias was evaluated using the Critical Appraisal tools in JBI Systematic Reviews. The meta-analysis compared the data obtained for the periodontal parameters analyzed, and the heterogeneity was verified. RESULTS After the screening, nine articles were included. Seven studies applied MIST and its modifications; two used M-PPT, one SPPT, and one approached EPP. A general statistically significant PD reduction and CAL gain were noted between the groups, comparing baseline and follow-up for all articles, independently of the technique or materials used. Also, all studies showed a non-significant increase in the gingival recession. Four studies had a low risk of bias, four had a moderate risk, and only 1 had a high risk. Moderate heterogeneity was found in one analysis for CAL (65.73%); moderate and substantial heterogeneity was found in the PD results (71.91% and 89.19%); and no heterogeneity was found within all analyses for gingival recession (0%). CONCLUSION MIST, M-MIST, and papilla preservation techniques demonstrated their potential and efficacy to improve periodontal conditions of sites with intrabony defects with minimal morbidity.

Clin Exp Dent Res 2024; 10:e853. [PMID: 38345463 PMCID: PMC10847703 DOI: 10.1002/cre2.853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 01/15/2024] [Accepted: 01/22/2024] [Indexed: 02/15/2024] Open
Abstract
OBJECTIVES This study assessed the effectiveness of prehydrated collagenated xenogenic bone gel and a collagenated cortico-cancellous heterologous bone mixture in conjunction with papillae tunneling techniques (PTT) for treating isolated periodontal intraosseous defects. MATERIALS AND METHODS Twenty patients with periodontitis stage III/IV and at least one deep isolated interdental 2/3-wall intraosseous defect were included in the study. Surgical incisions were made vertically at the adjacent tooth or horizontally at the mucogingival junction. A full-thickness flap was then carefully lifted under the papillae using special tunneling instruments. The root surfaces were completely cleaned, and the defects were randomly filled with either prehydrated collagenated bone gel (test group; n = 10) or collagenated cortico-cancellous heterologous bone mixture (control group; n = 10). Wounds were closed with microsurgical sutures. We predicted that the lower 95% confidence interval for the difference between the two procedures would exceed a prespecified noninferiority threshold. RESULTS All wounds closed sufficiently to prevent biomaterial exposure. The test and control groups showed similar mean pocket depth reduction (3.5 ± 1.0 vs. 3.9 ± 1.7 mm; p = 0.52), similar gingival recession (-0.10 ± 0.99 vs. 0.2 ± 0.8 mm; p = 0.46), and similar clinical attachment gain (3.6 ± 1.51 vs. 3.7 ± 1.8 mm; p = 0.89) at the 12-month follow-up. All results were below the noninferiority margin of the sample. CONCLUSIONS At 12 months, prehydrated collagenous bone gel performed similarly to collagenous heterologous bone granules in the treatment of intraosseous lesions with PTT. In addition, both biomaterials preserved soft tissue with minimal further recession at 1 year. CLINICAL RELEVANCE When combined with PTT, collagenous xenogeneic bone granules and prehydrated collagenous bone gel achieve comparable clinical outcomes in intrabony defects. The study was registered under the NCT04782921 on ClinicalTrails.

Abstract
BACKGROUND Gingival recession and post-operation discomfort are still a problem for patients receiving the periodontal regeneration surgery for intra-bony defects. To further reduce the trauma and the post-operation gingival recession, a novel periodontal endoscopy-aided non-incisional regeneration technique (NIT) was proposed in the treatment of intra-bony defects. METHODS Retrospective analysis of 21 subjects treated with NIT and 21 subjects with periodontal endoscopy-aided scaling and root planing (PSRP) at baseline and 1-year evaluation was conducted. After removing the subgingival calculus and granulation tissue, bone grafting materials were placed into intrabony defects with the assistance of a gingival retractor in the NIT group. Probing depth (PD), gingival recession (GR), clinical attachment level (CAL), as well as the distance between bone crest (BC) level and base of the defect (BD) (intrabony defect depth, IBD) were evaluated at baseline and 1 year after treatment. RESULTS At 1-year follow-up, the value of CAL, PD and IBD were statistically significant different compared with baseline in both two groups (p<0.001). CAL gain (p = 0.012) and PD reduction (p = 0.004) was greater in the NIT than PSRP. However, no difference in the IBD reduction was found between the NIT group and PSRP. Better CAL gain and PD reduction was achieved in the 1-year term in the NIT when compared with PSRP. CONCLUSION NIT have resulted in significant gains in both clinical and radiographic parameters. NIT might be utilized as an alternative of the surgical treatment for periodontal intrabony defects. TRIAL REGISTRATION This clinical trial registration was registered retrospectively (August 3, 2023) and the number is ChiCTR2300074317.

Abstract
OBJECTIVES To evaluate the clinical, radiographic, and esthetic outcomes of immediate implant placement with buccal bone dehiscence in the anterior maxilla. METHODS In this case series, implants were inserted immediately after tooth extraction in sockets with buccal bone dehiscence. Guided bone regeneration (GBR) with a papilla preservation flap and simultaneous connective tissue grafting (CTG) was used. The following outcome variables were measured: mid-facial mucosal recession, probing depth, bleeding on probing, Pink Esthetic Score (PES), marginal bone loss, and thickness of buccal bone plate (TBP). RESULTS 12 patients were recruited. Stable mid-facial mucosal level (-0.03 ± 0.17 mm) and excellent soft-tissue esthetic outcomes (PES, 9.17 ± 0.72) were achieved at 1 year. The TBP at platform level was 2.01 ± 0.31 mm at 1-year follow up with a resorption rate of 28.90% ± 15.14%. CONCLUSIONS Immediate implant placement using GBR performed with a papilla preservation approach and simultaneous CTG is a feasible treatment procedure in compromised extraction sockets in the anterior region. Favorable esthetic outcomes and buccal bone thickness were obtained. Further studies were needed to evaluate the long-term tissue alteration.
