Eight patients (3 males and 5 females) were selected for this procedure and treated between February 2016 and December 2017. All these patients had a deficient vertical height of the posterior mandibular alveolar bone above the inferior alveolar canal. The particulate deproteinized organic bovine bone graft (Bio-Oss) mixed with blood was placed through the tunnel in the defected area and compacted firmly to form a dense pack. The average gain of alveolar bone in the first implant site immediately postoperative was 13.51 ± 0.85 and in the second implant site was 13.84 ± 0.62. Histomorphometric analysis showed that about 70.31% of the area analyzed was occupied by the vital bone, the newly formed bone, whereas only 29.69% of the residual graft remained. In the present pilot study, the deproteinized bovine bone graft placed to enhance vertical and horizontal bone gain showed positive results in regaining the bone needed to place implants and maintaining the bone around restored implants for 4 years of follow-up.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"27-35"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848748","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}

This prospective case series included 4 male patients (mean age, 34.5 years; range, 20-49 years) with anterior maxillary bone defects. Bone augmentation was performed using a staged guided bone regeneration technique with PLGA mesh sheets as barrier membranes and a 1:1 mixture of autogenous and xenogeneic bone as grafting material. The effectiveness of bone augmentation was evaluated using preoperative and postoperative computerized tomography data at 1 and 6 months. Secondary outcomes included complications such as wound infection and dehiscence. The treatment of the 4 patients required 7 PLGA mesh sheets and particulate bone, followed by 9 implant placements. Wound healing was uneventful except for 1, wherein wound dehiscence and graft loss were observed. One patient had an exposed PLGA mesh sheet during healing, necessitating its removal. The mean vertical bone gain was 2.3 ± 0.5 mm, and the mean horizontal gain was 3.7 ± 1.3 mm at 1 month postoperatively. Sites without wound dehiscence exhibited a bone decrease rate of 6.5%-21.1%, whereas successful bone height and width increases were observed across treated sites. Bone augmentation using PLGA mesh sheets proved effective in reconstructing horizontal and vertical alveolar bone dimensions. This technique provides adequate support for implant placement, demonstrating its potential utility in cases of substantial alveolar bone deficiency.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"60-66"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804124","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}

A total of 30-cylinder shaped specimens having 1.0- and 2.0-mm buccal thicknesses using 5 different gingiva-colored composites [light pink (LP), dark pink (DP), orange (Or), brown (Br), and purple (Pr)] were prepared. Implants were placed straight into the center of cylinders and connected to abutments [Titanium (Ti) and Zirconia (Zr)]. Color parameters were assessed using a spectroradiometer. Color differences (ΔE*ab and ΔE00) were calculated and compared with 50:50% perceptibility (PT) and acceptability (AT) visual thresholds. Color variation data were statistically analyzed using 2-way analyses of variance followed by Tukey HSD tests (a = .05). Significantly higher ΔE*ab and ΔE00 values were recorded in LP and Or groups with 1.0 mm buccal thickness and Ti abutments (P < .05). Regardless of the thickness applied, all the gingival color groups with Zr abutment presented ΔE*ab and ΔE00 values below AT. The mean ΔE*ab value decreased as the gingiva thickness increased in the LP, DP, and Or groups with Ti abutments. Abutment material significantly affected the mean ΔE00 values in the groups of LP, DP, and Or with a buccal gingiva thickness of 1.0 mm (P < .05).

Twenty female Lewis rats were divided into 2 groups (n = 10 each). In one group, the periosteum was prepared with a conventional periosteal elevator; in the other, a piezoelectric device was used. After graft implantation at calvarial sites, intravital microscopy was performed postoperation (day 0) and on days 3, 8, and 28 immediately to assess microvascular parameters: functional capillary density, blood flow velocity, and vessel diameter. Statistical analysis was conducted using analysis of variance on ranks with P < .05. The piezoelectric device group showed higher mean values for functional capillary density, blood flow velocity, and vessel diameter than the conventional instrument group, though differences were not statistically significant. This study suggests that periosteum preparation with a piezoelectric device does not significantly differ from conventional methods regarding microcirculatory outcomes. Either method appears viable for preserving microcirculatory integrity during bone augmentation.

Beta-tricalcium phosphate calcium sulfate (β-TCP/CS) is a novel material with self-hardening and tissue growth inhibition properties and can potentially replace the need for a membrane. This study compares β-tricalcium phosphate/calcium sulfate with deproteinized bovine bone mineral and a collagen membrane (DBBM/CM) to repair bone defects at implant sites over 6 months. Sixteen implant defects were divided into β-TCP/CS (n = 8) and DBBM/CM (n = 8). The results showed no significant differences in vertical and horizontal defect fill in millimeters between β-TCP/CS (2.87 ± 1.25 and 2.37 ± 1.06 mm, respectively) and DBBM/CM (3.5 ± 0.92 and 2.87 ± 1.12 mm, respectively). Buccal bone thickness (BT) alterations at the implant platform levels (BT0) were similar for both materials. However, β-TCP/CS exhibited greater bone alteration at the 2-mm level (BT2: -1.85 mm vs -0.47 mm) and 4-mm level (BT4: -1.79 mm vs 0.12 mm) apical to the implant platform compared to DBBM/CM. When assessing volume alteration, β-TCP/CS showed a significantly greater reduction at the platform to the 2 mm level (-61.98% vs -23.76%) than DBBM/CM. In conclusion, β-TCP/CS demonstrated promise for treating buccal bone defects around implants but exhibited higher graft reduction. This suggests that while β-tricalcium phosphate/calcium sulfate may offer clinical benefits, its potential for greater graft reduction should be considered. Further research and evaluation are warranted to fully understand the long-term implications of using β-TCP/CS in guided bone regeneration procedures.","PeriodicalId":519890,"journal":{"name":"The Journal of oral implantology","volume":" ","pages":"6-13"},"PeriodicalIF":0.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368162","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}

Full-thickness flaps were raised during surgery, and the remaining teeth were extracted. Implants and multiunit abutments were placed, followed by impressions and the recording of the interjaw relationship using index dentures. After 6 months of osseointegration, the reverse scan technique was employed, using light silicone, reverse scan bodies, and extraoral scanning to capture implant positions, soft tissue profiles, and prosthesis shapes. Titanium frames were machined for the final prostheses-monolithic zirconia for the maxilla and zirconia crowns with composite gingiva for the mandible.
