There is a specific lack of evidence for alveolar ridge reconstruction at molar and premolar sites with severe bone resorption. This randomized controlled trial used 3D and linear analyses to evaluate volumetric changes of the alveolar bone following alveolar ridge reconstruction (ARR) at molar and premolar sites with severe bone resorption as compared to unassisted socket healing before implant placement. A total of 31 patients (15 men, 16 women) with > 50% hard tissue loss in one or more socket walls were recruited and randomized into either a test group (postextraction ARR using deproteinized bovine bone mineral with 10% collagen [DBBM-C] and platelet-rich fibrin [PRF] with a resorbable collagen membrane) or a control group (natural healing after extraction). The clinical, linear, and volumetric implant-related and patient-reported outcomes were analyzed after 4 months of healing. Linear bone assessments revealed significantly greater ridge width gains in the test group (25% in the mesial, midfacial, and distal aspects) and less reduction of vertical bone ridge than in the control group (P < .05). Further, volumetric bone remodeling was significantly higher in the test group (35.1% ± 34.9% for ARR, 14.2% ± 12.8% for control; P < .05). Patient-reported discomfort and keratinized mucosal changes were comparable between groups. ARR with a combination of DBBM-C, PRF, and a resorbable membrane at posterior sites with a severe socket wall deficiency (> 50% bone loss) is a safe and more capable therapeutic method when compared to natural healing and unassisted sockets. Collectively, the present analyses demonstrate that ARR represents an efficient method to maintain and augment crestal bone at posterior extraction sites with severe bone defects when assessed after 4 months of healing.</p>","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"673-683"},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139418886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All cases were treated with apicoectomy in conjunction with a connective tissue graft (CTG), and the first steps of each case were as follows: endodontic therapy with root-end resection and retrograde filling, then regenerative surgical therapy.

In Case 1, gingival fenestration in the mandibular left first premolar was treated using a xenograft and CTG. In Case 2, gingival fenestration in the maxillary left lateral incisor was treated using advanced platelet-rich fibrin (A-PRF) and CTG. In Case 3, gingival fenestration in the mandibular left second premolar was treated using CTG. Endodontic treatment was combined with periodontal surgery to achieve predictable results. After 13 to 25 months of follow-up, all cases showed well-healed gingival fenestrations and no discomfort.

Numerous techniques have been explored to reconstruct and regenerate interdental papillae, but consistent success remains challenging. This article presents a novel surgical approach that applies the principles of the Connective Tissue Graft (CTG) wall technique to enhance papilla volume when interdental clinical attachment loss is present in the aesthetic zone. The case of a 35-year-old woman with an RT3 recession defect associated with loss of interdental hard and soft tissues is discussed. The patient underwent a procedure involving palatal incisions, application of amelogenins, and a trapezoidal shape CTG fixed at the base of the papilla under a coronally advanced flap. This approach aimed to stabilize the blood clot and prevent soft tissue collapse into the defect area, enhancing the position and volume of the interdental papilla. Results at 6- and 12-months follow-up indicated significant improvement in papilla appearance and complete root coverage. This case suggests that the modified CTG wall technique can effectively treat buccal and interdental gingival recessions associated with horizontal or infrabony defects. Further clinical trials are necessary to confirm these findings and establish the most effective approach for interdental papilla reconstruction.</p>","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-20"},"PeriodicalIF":0.0,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The supra-crestal sling (SCS) suture engages only the CTG, independent of the overlying tissue and stabilizes the CTG around the buccal and proximal root surfaces.

A literature search was conducted to identify investigations that fulfilled a set of pre-defined eligibility criteria based on the PICO question: what is the effect of SPIC upon peri-implant tissue stability following non-surgical and surgical interventions for the treatment of peri-implant diseases in adult human subjects? Data on SPIC (protocol, frequency, and compliance), clinical and radiographic outcomes, and other variables of interest were extracted and subsequently categorized and analyzed. A total of 8 studies, with 288 patients and 512 implants previously diagnosed with peri-implantitis were included. No studies including peri-implant mucositis fit the eligibility criteria. Clinical and radiographic outcomes were similar independently of specific SPIC features. Nevertheless, a 3-month recall interval was generally associated with a slightly lower percentage of disease recurrence. The absence of disease recurrence at the final follow-up period (mean of 58.7±25.7 months) ranged between 23.3% and 90.3%.
