摘要: 目的 通过对块状或片状自体骨植骨病例的长期随访研究,评价其骨增量方法的有效性及临床效果,分析影响块状或片状自体骨移植及种植成功的因素。材料与方法 通过回顾研究自2000年以来,作者团队采用块状或片状自体骨技术恢复牙槽嵴水平向或垂直向骨缺损,对植骨治疗后5年以上的66个病例,测量植骨前后及种植体植入时植骨区的体积变化,统计块状或片状自体骨块移植成功率、种植体留存率及并发症的发生情况,分析其植骨治疗影响因素。结果 共有89名患者完成自体骨移植,排除失访等病例,最终纳入66名患者,其中,水平骨增量50例,垂直骨增量16例,共116个种植位点;平均随访时间8.1年。骨吸收率分别为9.0%和10.9%,自体骨的成活率为95.8%,种植体留存率为95.7%。其中3例出现骨块松动,5例发生种植体周炎,1例发生下牙槽神经支配区软组织麻木。结论 块状或片状自体骨移植可以安全有效的重建牙槽嵴重度骨缺损,而自体骨的良好固定、合适的技术选择和软组织瓣的处理对植骨成功及减小术后骨吸收具有重要影响。

Abstract: Objective The aim of this study is to evaluate the efficacy and long-term clinical outcomes of autogenous bone block/laminar reconstruction of alveolar ridge defect, and analyze the key factors affecting the success rate of autogenous bone graft and implants. Methods And Materials This retrospective study was conducted from January 2000 to December 2015. A total of 66 patients underwent autogenous onlay bone graft to reconstruct bone defect were enrolled in this trial, and all the patients were followed-up for at least 5 years, The width and vertical height of alveolar bone were measured at the time of surgery and reentry surgery. Integration of graft, implant survival rates and complications were recorded. Results 89 patients were screened for eligibility. Eventually, 66 patients with 116 implant sites were enrolled in this trial. Of these, 50 patients received horizontal augmentation, while 16 received vertical augmentation. The average of follow-up was 8.1 years. Bone resorption rate after horizontal and vertical augmentation was 9.0% and 10.9% respectively. Graft integration and implant survival rates were 95.8% and 95.7% respectively. 3 bone blocks failed to integrate. Among all the 116 implants, periimplantitis occurred in 5 cases. 1 case presented paresthesia lasting up to 6 months because of minor nerve impairment. Conclusion This study demonstrated that autogenous bone graft was effective and reliable for reconstruction of severe atrophic alveolar ridges. Favorable fixation, appropriate technology selection and flap management had great influence on graft integration and bone maintenance.
