目的:本研究的目的是評估在先前失敗的位置進行植體再植入的存活率,並評估後續的存活率以及其他因素對於存活率的影響。方法:本研究由電子資料庫Pubmed搜尋從1986至2022年6月以英文撰寫的文獻。本文會根據納入研究的樣本來計算加權平均存活率,另外會利用勝算比(Odds ratio, OR)來比較不同的因素與再植入存活率的關係。結果:總共納入13篇文獻,顯示再植入植體的平均存活率為88.9%。根據病人相關因素、植牙因素、部位因素以及其他因素進行後設分析,發現大部分的因素對於再植入的存活率並不會有顯著的影響。然而在植體表面處理方面,有經過表面處理的植體其勝算比為4.15(95%信賴區間範圍:1.83 - 9.45),顯示表面經過處理的植體表面其存活率顯著優於平滑的植體表面。結論:根據目前的文獻顯示,再植入植體的平均存活率為88.9%。因此,在先前植體失敗的位置進行再植入是一項可行的治療方式。此外,使用經過表面處理的植體相較於平滑表面的植體能夠得到更高的再植入存活率。
Purpose: The purpose of this study was to perform a systematic review and meta-analysis to evaluate the survival rate of reimplantation and identify the potential risk factor for implant failure. Materials and methods: Articles written in English were collected from PubMed electronic databases from January 1986 to June 2022. Survival of reimplantation was studied. Besides, odd ratio was used to clarify the relationship between different risk factors and the survival rate of retreated implants. Only the studies with more than 1-year follow-up were included. Results: A total of 13 papers were included in the meta-analysis. The mean survival rate for re-implantation was 88.9%. Based on a meta-analysis of patient-related factors, implant factors, site-specific factors, and other factors, it was found that most factors have an insignificant impact on the survival rate of re-implantation. However, in terms of implant surface, the odds ratio for treated implant surfaces was 4.15 (95% confidence interval:1.83-9.45), indicating that the survival rate of implants with rough surface was significantly superior to machined surface implant. Conclusion: According to the review, mean survival rate of reimplantation was 88.9%. Therefore, reimplantation was a feasible option for implant failure. Moreover, the meta-analysis showed higher survival rate in rough surface implants than that in machined surface implants.
