To overcome difficulties in shaping and adapting meshes to the defect, digital techniques were introduced to digitally print meshes capable of fitting the bone perfectly, reproduced through the patient's CT scan. Five patients were included in this case series, and their CBCT data were acquired and sent to the producer of the titanium meshes. 3D regenerative surgery was performed with titanium meshes and a mix of demineralized bovine bone matrix (DBBM) and autogenous bone (1:1 ratio). Radiographic measures were evaluated on paraxial sections of the CBCT through a dedicated software. When possible, regenerated bone samples were obtained at implant insertion. Four out of five regenerated areas healed without local or systemic complications. One mesh was removed after 2 months and 2 weeks due to exposure. The mean vertical bone gain was 4.3 ± 1.5 mm (range: 2.5 to 7 mm). Two histologic samples were obtained.

Most of these techniques are suitable for isolated recession sites and involve harvesting an autogenous tissue graft, which increases patient morbidity and might result in inferior esthetics due to incision design. This study assessed the benefit of adding platelet-rich fibrin (PRF) to the vestibular incision subperiosteal tunneling approach (VISTA) in treating multiple gingival recession compared to using VISTA alone. A total of 41 teeth with Miller Class I and II defects were randomized in a split-mouth design. Multiple clinical parameters were tested, including the change in gingival thickness over time, keratinized tissue width, and gingival phenotype (using the transparency of a periodontal probe). Patient-centered outcomes were also assessed via visual analog scale. Multiple Miller Class I and II recessions in the maxilla can be effectively treated with VISTA. However, when used in conjunction with PRF, no significant differences were detected in any parameter. VISTA has been shown to be associated with a low level of postsurgical pain for patients and can be used for patients with high esthetic demands.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"44 3","pages":"267-275"},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141094829","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}

Several bone substitutes are indicated for sinus augmentation, but they may achieve different clinical outcomes. This study aims to compare bovine bone mineral (BBM) with freeze-dried bone allograft (FDBA) in a two-stage lateral window sinus grafting approach. Twenty patients received a lateral window sinus elevation with either FDBA or BBM. Postoperative graft height was measured with CBCT. Implants were placed 6 months later, at which time biopsy samples were taken for histologic analysis and new CBCT scans were performed to measure graft height. The mean height reduction at 6 months was 20.27% ± 4.94% for FDBA samples and 5.36% ± 2.41% for BBM samples. The histologic analysis revealed a mean ratio of newly formed bone of 43.70% ± 5.29% for the FDBA group and 38.11% ± 4.03% for the BBM group. The FDBA group also showed a higher amount of residual biomaterial (17.25% ± 10.10%) and connective tissue (14.63% ± 4.38%) compared to the BBM group (15.53% ± 5.42% and 13.11% ± 4.42%, respectively). The differences between groups were statistically significant for the height reduction and newly formed bone (P ≤ .05) but not for the amounts of residual biomaterial and nonmineralized connective tissue (P ≥ .05). Six months after performing a lateral window sinus elevation, the percentage of newly formed bone was significantly higher when using FDBA than when using BBM, although the graft height reduction was also significantly higher for the FDBA group.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"44 3","pages":"309-319"},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141094816","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}

Twelve patients were enrolled in an immediate implant placement procedure with immediate aesthetic rehabilitation to replace an anterior maxillary tooth, and were treated with inverted body-shift design with 12° angled neck. Only type I sockets according to the Elian classification were considered eligible for the study. There were no implant failures after one year of loading.

This study compared bone regeneration using occlusive or perforated membranes combined with acellular collagen sponge (ACS) and recombinant human bone morphogenic protein-2 (rhBMP-2) in a canine mandibular model.Material and methods: Male beagle dogs (n=3) received two mandibular defects each to compare ACS/rhBMP-2 with experimental (perforated group) and control (non-perforated group) membranes (n=3 defects/group). Tissue healing was assessed histomorphologically, histomorphometrically and through volumetric reconstruction using microcomputed tomography.Results: The perforated group showed increased bone formation and reduced soft tissue formation compared to the non-perforated group. For the primary outcome, histomorphometric analysis revealed significantly greater total regenerated bone in the perforated group (67.08 ± 6.86%) relative to the nonperforated group (25.18 ± 22.44%) (p = 0.036). Perforated membranes had less soft tissue infiltration (32.91 ± 6.86%) compared to non-perforated membranes (74.82 ± 22.44%) (p = 0.036).Conclusion: The increased permeability of membranes in the perforated group potentially enabled periosteal precursor cells greater accessibility to rhBMP-2.

Since then, several systematic reviews have been published, showing good clinical outcomes. The behaviour of the buccal bone plate is so far not completely understood.Methods: The study involved the placement of 23 implants using the socket shield technique in 20 patients. AstraTech EV implants were used, and no bone substitutes or connective tissue grafts were applied. Patients were monitored for 18 months, recording implant survival, volumetric bone analysis on CBCT scans, interproximal bone levels, bone sounding, pink esthetic scores, and complications. Prosthetic procedures were also described, including temporary and final restorations.Results: A 95.7% cumulative 18-month implant survival rate was obtained using the socket shield technique, with a significant but limited reduction in buccal bone thickness (BBT) after implant placement. One implant did not integrate and two shields were partially exposed. The mean pink esthetic score, 1 year after loading was 12.93 ± 1.22.Conclusion: The study suggests that the socket shield technique can result in limited reduction of the buccal bone volume, with a high implant survival rate.
