目的:评估种植体支持的单端悬臂修复的留存率、成功率(无并发症)和边缘骨吸收,并评价悬臂长度对种植体支持的单端悬臂修复效果影响。方法:检索截止2016年5月1日在Pubmed和Cochrane Central Register of Controlled Trials数据库收录的相关英文临床研究文献,从符合纳入标准的文献中提取种植体留存率、种植修复成功率和边缘骨吸收等数据并进行meta分析。结果:检索到相关的题目和摘要263条,最终纳入16篇文献。6篇文献报道了种植体支持的局部固定义齿,meta分析显示是否带有单端悬臂梁对其成功率、种植体留存率和边缘骨吸收均无显著影响。10篇文献报道了种植体支持的全口义齿,其种植体留存率为97%~100%,种植修复成功率为52%~98%,平均边缘骨吸收为0.23~1.73 mm。没有文献报道悬臂长度对种植修复有不良影响。结论:种植体支持的单端悬臂修复体是一个可预期的治疗选择。当种植体支持的局部固定义齿悬臂梁<9 mm,种植体支持的全口义齿悬臂梁<15.6 mm时,可以获得较好的临床疗效。
OBJECTIVE: To assess the effect of implantable single-ended cantilever repair on survival, success (no complications) and marginal bone resorption, and evaluate the effect of cantilever length on single-ended cantilever repair supported by the implant. METHODS: We searched relevant English clinical studies published in the Pubmed and Cochrane Central Register of Controlled Trials databases as of May 1, 2016, and extracted implant retention rates, implant repair success rates, and marginal bone resorption from eligible documents Data and meta-analysis. Results: 263 related topics and abstracts were retrieved, and finally 16 articles were included. Six articles reported implants supported by local fixation dentures. Meta-analysis showed no significant effect of single-ended cantilever on success rate, implant retention and marginal bone resorption. Ten articles reported on implant-supported complete dentures with implant retention of 97% -100%, implantation success rate of 52% -98%, and mean border bone resorption of 0.23-1.73 mm. No literature reports that cantilever length has a detrimental effect on implant repair. Conclusion: Implant-supported single-ended cantilever prostheses are a predictable treatment option. When the implant supported partial denture cantilever <9 mm, implant supported denture cantilever beam <15.6 mm, you can get a better clinical effect.
