【摘要】：目的:系统评价平台转移技术与平台匹配对种植体边缘骨吸收的影响。方法:计算机检索Pub Med、EMbase、CBM、CNKI等数据库辅以手工检索及文献追溯收集1991~2014年间国内外公开发表或未发表的有关平台转移技术与平台匹配对种植体边缘骨吸收的影响的随机对照实验,由2位评价者根据纳入与排除标准独立筛选文献,对纳入研究进行质量评价、数据提取,采用Rev Man 5.2软件进行Meta分析。结果:符合纳入标准合成文献14篇包含1 331颗种植体,Meta分析结果显示:平台转移组种植体边缘骨吸收显著小于平台匹配组[MD=-0.51,95%CI:(-0.72-0.30),P0.01]。亚组分析显示,植入物-基台直径差0.45 mm(单侧)更有利的种植体边缘骨保存。结论:现有的有限数据表明,平台转移技术相对于平台匹配技术更利于种植体边缘骨保存。
[Abstract]:Objective: to systematically evaluate the effect of platform transfer technique and platform matching on bone resorption at the implant edge. Methods: Pub Medbase Pub was searched by computer. CNKI and other databases are supplemented by manual retrieval and literature traceability. The effects of platform transfer techniques and platform matching on bone resorption at the edge of implants were published or unpublished in China and abroad during the period from 1991 to 2014. Randomized controlled trial. According to the inclusion and exclusion criteria, two evaluators independently screened the literature, evaluated the quality of the inclusion study, and extracted the data. Meta analysis was carried out with Rev Man 5.2 software. Results: 14 articles including 1 331 implants were included in the standard of inclusion. The results of Meta analysis showed that the bone resorption at the implant edge in the platform transfer group was significantly smaller than that in the platform matched group. [MD-0.51-95% CI-1: -0.72-0.30 (P0.01). Subgroup analysis showed. Implant-abutment diameter difference of 0.45 mm (unilateral) is more favorable for the preservation of marginal bone of implant. Conclusion: available limited data indicate. Platform transfer technique is more favorable than platform matching technique in bone preservation of implant edge.
