Abstract:

Objective: The aim of the clinical study was to evaluate bone healing of localized ridge defects treated with deproteinized bovine bone mineral (DBBM) particles without the use of biomembranes, but with the integrated periosteum; and compare its result with that of conventional guided bone regeneration(GBR).Methods: In this study, 32 patients who underwent single tooth implant surgery and horizontal bone augmentation in the same period from 2017 to 2019 were reviewed. They were divided into GBR group and periosteum guided bone regeneration（PGBR） group randomly. The bone volume and soft tissue were examined through radiographic measurement and clinical examination at follow-up. Results: Clinical and radiography examinations indicated that there were no peri-implant radiolucency, mobility, or peri-implant inflammation at follow-up. GBR group received average horizontal bone gain of (1.83±1.59) mm, and the mean bone gain of PGBR group was (1.97±1.45) mm, there was no statistically significant difference between the two groups. Conclusion: The use of the integrated periosteum with DBBM grafting can be a predictable and alternative option for reconstructing horizontal bone defects in single missing tooth.

摘要：

目的：探究用完整的骨膜覆盖骨替代材料而不使用生物胶原膜的骨膜引导骨再生技术与传统的引导骨再生技术（guided bone regeneration, GBR）对水平骨缺损的牙槽骨及软组织愈合修复结果比较。方法：本研究对2017—2019年行单颗牙种植手术同期水平骨增量手术的患者进行回顾分析，共纳入32例患者，随机分为引导骨再生组和骨膜引导骨再生组，并在后期随访过程中通过影像学检查及临床检查获取骨量变化及软组织数据。结果：所有病例均未出现种植体周围透射影、种植体周黏膜炎或种植体周炎。对于水平骨获取量，引导骨再生组为（1.83±1.59） mm，骨膜引导骨再生组为(1.97±1.45) mm，两组在成骨效果上无明显差异。结论：将Bio-oss脱蛋白小牛骨颗粒与完整的骨膜以骨膜引导骨再生的方法应用于单颗牙缺失水平骨缺损的同期种植病例中，其结果是可预期的，可以作为牙槽骨重建的替代方法。
