【摘要】 目的 系统评价种植体光滑颈圈与粗糙颈圈对种植体边缘骨吸收的影响。方法 电子检索Embase、PubMed、知网、万方数据库并引文检索，检索时限为建库至2024年6月。由2名研究员独立筛选、审阅、评估相关文献，使用RevMan5.4和Stata15.0软件进行Meta分析。结果 共纳入7篇文献，702颗种植体。Meta分析显示，粗糙颈圈组种植体边缘骨吸收明显小于光滑颈圈组[MD=0.34,95%CI(0.08,0.61),P<0.05]。亚组分析显示，当种植体植入时间在12个月以内时，粗糙颈圈对种植体边缘骨保存的优势更加显著。结论 基于现有证据表明，种植体粗糙颈圈相较于光滑颈圈更有利于种植体边缘骨的保存。更多还原

【Abstract】 Objective To systematically evaluate the effect of smooth and rough implant collars on marginal bone resorption. Methods A systematic search was conducted in Embase, PubMed, CNKI, and Wanfang databases from inception to June 2024. Two independent reviewers screened, analyzed, and assessed the relevant literature. Metaanalysis was performed using RevMan 5.4 and Stata 15.0. Results Seven studies, involving 702 implants, were included. The meta-analysis showed that marginal bone resorption in the rough collar group was significantly lower than in the smooth collar group [MD=0.34,95% CI(0.08,0.61),P<0.05]. Subgroup analysis showed that the advantage of the rough collar in preserving marginal bone was more significant when the implant placement duration was less than 12 months. Conclusion Based on the available data, the rough implant collar is more favorable for marginal bone preservation compared to the smooth collar.更多还原
