However, alveolar bone destruction due to severe periodontitis, trauma, or other pathological conditions may compromise implant placement in an idea position. Ridge augmentation with autogenous bone blocks can be used to reconstruct the deficiency of the alveolar bone. This article reviewed about the relevant literatures and reported two cases of severe ridge atro¬phy using staged approaches with ridge augmentation using autogenous bone block grafting and implant placement for reconstruction. Case 1 showed alveolar bone destruction caused by severe periodontitis at left maxillary region, which was augmented with the autogenous bone block harvested from mandibular symphysis in combination with FDBA and collagen membrane. Case 2 presented alveolar ridge deficiency after tooth extraction due to severe periodontitis. Ridge augmentation was performed using autogenous bone block harvested from the mandibular ramus along with FDBA and collagen membrane. Both cases showed increased bone volume after ridge augmentation. Implants were successful and presented stable bone level for a follow up period at least one year after implant surgery. The literature review and case reports suggest that with appropriate case selection, careful treatment, and regular maintenance, using autogenous block bone grafts harvested from the mandibular symphysis or ramus for ridge augmentation and implant placement can achieve predictable outcomes.","PeriodicalId":150986,"journal":{"name":"Journal of Periodontics and Implant Dentistry","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139328202","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}

Demineralized bone matrix (DBM) comprises a human allograft that is osteoinductive and osteoconductive. This report describes radiographic, histologic and clinical findings of ARP using DBM putty and non-resorbable high-density polytetrafluoroethylene (d-PTFE) membrane in three cases. Materials and Methods: From January 2018 to May 2018, three patients underwent the ARP procedure. The surgery involved atraumatic extraction, socket debridement, filling the socket with DBM putty, applying a d-PTFE membrane, and suturing with 5-0 nylon. After healing for 6–7 months, an implant was placed and biopsy specimens were collected simultaneously. Using the same customized surgical stent and computed tomography, the preoperative and postoperative alveolar ridge heights and widths were measured. Histological evaluations in¬cluding the percentage of newly formed bone, residual graft particles, and fibrous connective tissue were performed. Results: In all three cases, the health status of the hard and soft tissue improved (mean fol¬low-up: 54 months). Guided bone regeneration was not required during implant placement. Radiographically, the mean change was 0.5 mm in the alveolar ridge height and 1.2, 0.87, and 0.73 mm in the alveolar ridge width at 2, 4, and 6 mm apical to the initial vertical measure¬ment, respectively. Histologically, the mean percentage of new bone, residual graft particles, and fibrous connective tissue was 40.5±5.9%, 10.7±6.9%, and 48.8±9.6%, respectively, and the voids were not included in these calculations. Conclusion: This case series demonstrated the effectiveness of DBM putty as a biocompatible filler in extraction sockets for ridge preservation prior to implantation. Further longitudinal studies regarding the efficacy and stability of DBM putty in ridge preservation are required.","PeriodicalId":150986,"journal":{"name":"Journal of Periodontics and Implant Dentistry","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139328272","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}

Besides, prevention of post-operative gingival recession is one of treatment goals for ideal regenerative surgery as well. The case reports tended to achieve periodontal regeneration and root coverage in teeth affected with both deep intrabony defects and the buccal gingival recession using the concept of connective tissue (CTG) wall technique combined with enamel matrix derivative (EMD) and bone graft materials. The surgeries involved a single flap approach (SFA) and augmentation of soft tissue, attempting to minimize post-operative gingival recession, by suturing the CTG on the inner surface of coronally advanced flap (CAF) as a barrier wall for the coronal portion of the bone defect. The bony defects were filled with allograft and/or xenograft as a space mak¬ing scaffold and followed by primary closure of wound. Significant probing depth (PD) reduc¬tion, clinical attachment level (CAL) gain and improvement in the level of gingiva margin were noticed after 7- and 11- months follow-up respectively. Comparisons of pre-operative and different periods of radiographic images demonstrated that the bone defects were indeed filled. It can be concluded that the CTG does support the bone regeneration and overlying soft tissue flap stability within the periods of observation. This surgical approach provides an alter-native aid on the clinical outcome of bone healing and root coverage simultaneously in deep intrabony defects.","PeriodicalId":150986,"journal":{"name":"Journal of Periodontics and Implant Dentistry","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139329930","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 success and stability of root-coverage outcomes depend on gingival thickness (GT), defect characteristics and anatomical limitations addressing hard and soft tissue relationships and periodontal structures. Root coverage is less predictable in the presence of interproximal attachment loss. Evidence on the treatment of multiple recession-type defects, particularly Miller Classes III and IV, is scarce. The modified coronally advanced tunnel technique (MCAT) has been report-ed to exert root-coverage effects in Miller Class III cases via partial papilla elevation. To gain surgical access in challenging anatomies, the use of additional vestibular incisions (vestibular incision subperiosteal tunnel access, [VISTA]) has been proposed. In this case report, two patients who underwent surgeries for Miller Class II-III recessions with thin phenotypes are described.

Also, we will discuss the different protocols and modifications of the socket shield technique. Material and methods: A PubMed, Cochrane Library, Embase database search was conducted to identify relevant publication up to March 2022. Result: 7 articles were included in our systemic review. The follow-up periods of the included literature ranged from 6 months to 4 years and contained 106 cases of socket shield technique (Test group) and 112 cases of conventional immediate implantation technique (Control group). None of the implants failed to have osseointegration. The horizontal bone loss at the crestal area in test group and control group ranged from 0.12~0.29mm and 0.29~1.45mm half a year post-operatively on CBCT, respectively. On the other hand, the vertical bone loss in test group and control group ranged from 0.28~0.36mm and 0.77~1.71mm half a year after operation on CBCT.

Materials and Methods: Two experimental degree II furcation defects were created in pig jaws, and cone-beam computed tomography (CBCT) images were taken before and after defect creation. Computer-aided design (CAD) models of scaffolds were produced by subtracting two CBCT images. For each defect, one 3DP resin block printed using a stereolithographic 3D printer served as the control, and three 3DP HA-based scaffolds were printed using an extrusion-based 3DP bioprinter. The resultant 3DP resin blocks and HA-based scaffolds were placed in the defects, and micro-CT images were taken to assess the fitness of the scaffolds. Results: Compared with the CAD models, the 3DP resin blocks and HA-based scaffolds showed approximately 90% and > 80% volume stability, respectively. Regarding the furcation defects, the linear adaptation ratio was approximately 90% for the 3DP resin blocks and > 70% for the 3DP HA-based scaffolds.

However, the previous cone-beam computed tomography (CBCT) analysis of maxillary anterior teeth in Taiwanese patients revealed that the higher probability of labial bony perforation (LBP) when immediate implant surgery due to undesirable labial ridge concavity. Therefore, this case series demonstrated an alternative strategic approach that combined prophylactic root resection and simultaneous guided bone regeneration (GBR), which could effectively achieve the prerequisites for IIPP and decrease the risks of LBP. Materials and Methods: In this retrospective case-series study, four clinical cases with one or more failing anterior teeth were included. Following the initial CBCT analysis, all cases showed insufficient implant bone support due to apical lesion or buccal bone concavity. Besides, all patient were highly esthetic demand. Thus, we performed the prophylactic root resection with an attempt to maintain gingiva contour, and simultaneous GBR for ridge augmentation. After 8-month uneventful healing, IIPP was accomplished in all cases. The change of bone volume was compared by the preoperative computed tomography scans with those obtained eight months later. The quantitative analysis was calculated by Wilcoxon Signed-Rank Test and Kruskal-Wallis Test.
