The socket shield technique presents a viable alternative for immediate dental implant placement in the esthetic zone. This pilot study aimed to evaluate the survival, complication rates, and marginal bone loss around body-shift implants placed in fresh extraction sockets with the socket shield technique to replace maxillary incisors. After socket shield preparation, 14 hopeless incisors were extracted and immediately replaced by a body-shift implant (Inverta, Southern Implants) at baseline. Patients were followed up for 12 to 39 months (mean: 18.1 ± 8.2 months). The average age was 52.3 ± 16.9 years, and the survival rate was 100%. One socket shield presented minimal internal exposure that was successfully treated with a connective tissue graft. The mean PES score was 12.9 ± 1.2. Mean interproximal marginal bone loss was -0.4 ± 0.5 mm. Body-shift implants can be a promising alternative for immediate tooth replacement combined with the socket shield technique. The superior esthetic outcomes remained stable, suggesting that the extra space created by the narrow cervical portion of the implant is beneficial for preserving the alveolar bone and limiting internal shield exposure.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9954924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of an osteoporosis-like experimental animal model is of great importance for the study of peri-implant osteogenesis in osteoporosis. The present authors aimed to establish a rapid modeling method of osteoporotic rabbits for implant-bone analysis and validate whether the models can affect the implant osseointegration. The present study included 29 female New Zealand rabbits (age: 5 to 6 months). Two rabbits were lost during anesthetization. Of the remaining 27 rabbits, 18 received an ovariectomy, with 9 receiving dexamethasone injections for 8 weeks (OVX+D group) and 9 receiving equivalent-volume saline injections (OVX group). As a control group, the remaining 9 rabbits were sham-operated and received an equivalent volume of normal saline (SHAM group). Then, serum biochemical markers of bone metabolism were detected and densitometric measurements were performed. Implants were then placed in the tibias of each rabbit. Bone samples (including implants) were obtained after 4, 8, and 12 weeks of healing and were subjected to histologic and histomorphometric analyses. The results showed that the OVX+D group experienced a 32% reduction in bone mineral density (BMD) from baseline. The BMD of the OVX+D group was significantly lower than that of the SHAM and OVX groups. Moreover, alkaline phosphatase (ALP) blood concentrations of in the OVX+D group were increased significantly. The osteoporotic rabbits exhibited marked decreases in osseointegration, characterized by slowed bone formation and decreased bone-to-implant contact (BIC). The combination of an ovariectomy and dexamethasone injections could experimentally induce osteoporosis in rabbits in the short term, which can be used as an appropriate animal model to study the osseointegration of implants under osteoporosis.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10806512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simply, the technique includes harvesting autogenous bone plates and utilizing them with external screw fixation. The rigidity of the bone plates enclosing the bony defect on both the buccal and lingual surfaces allows for tension-free bone remodeling to occur, favoring an ideal bone-forming environment. Following, a 4- to 6-month healing period, a flap is raised, screws may be removed, and implants are placed. With advancements made in tissue engineering, a novel mineral-organic resorbable bone adhesive (MORBA) formulated from underwater biomimetic marine proteins has recently been utilized for immediate bone-to-bone or bone-to-metal fixation. MORBA is a synthetic, injectable, self-setting, and resorbable load-bearing adhesive biomaterial that exhibits over 300 pounds of fixation strength. The unique adhesive properties of MORBA enable it to immediately stabilize dental implants into host bone. The present article describes a novel modification of the Khoury plate technique that utilizes MORBA as a substitute for screws during bone plate fixation. A step-by-step protocol is described that utilizes this novel biomaterial, favoring a more biologic approach to this conventional technique. This novel modification is surgically easier to conduct and is a more biocompatible option that avoids screw fixation and removal.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9956928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
