The aim of this systematic review and meta-analysis was to analyze and compare the effect of diamond drill, tungsten carbide drill and ultrasound tips for implantoplasty procedures on the fracture resistance of dental implants affected by periimplant disease.

Materials and methods: This systematic review of the scientific literature and meta-analysis was carried out based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), analyzing all studies that evaluated the fracture resistance of dental implants submitted to implantoplasty through diamond drill, tungsten carbide drill and ultrasound tips for implantoplasty procedures, comparing with the fracture resistance values of non-treated dental implants. A total of 4 databases were searched in the literature: Pubmed, Scopus, Cochrane and Web of Science. After eliminating duplicate articles and applying certain inclusion criteria, a total of 9 articles were selected and compared using the random effects model and inverse variance method. The significance of the effect size was measured with the z test, the heterogeneity using the Q test and the I ² and publication bias was analyzed using the trim-and-fill method.

Results: The difference in means between the treatment and control groups was estimated as the effect size, obtaining a statistically significant difference of -232.01 MPa., with a 95% confidence interval of the difference between -417.3 and -44.71 (z test = -2.43; p-value = 0.015). The meta-analysis has presented high heterogeneity with an I ² = 99.3% and a Q test = 2,195.7; p-value < 0.001. No significant differences were found between the three subgroups with the Q test = 0.20: p-value = 0.903.

Conclusions: the tungsten carbide drills resulted in less fracture resistance loss than the diamond and tungsten carbide drills for the dental implants submitted to implantoplasty procedures. Systematic Review Registration: [http://www.prisma-statement.org], identifier [INPLASY202460018].

本系统回顾和元分析的目的是分析并比较钻石钻、钨钢钻和超声波磨头在受 periimplant 疾病影响的牙种植体成形术中的效果。

材料与方法： 本次科学文献系统的回顾和元分析是根据 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 的建议进行，分析了所有评估接受钻石钻、钨钢钻和超声波磨头成形术的牙种植体断裂抗力的研究，并将其与未经治疗的牙种植体的断裂抗力值进行比较。在文献中搜索了 4 个数据库：Pubmed、Scopus、Cochrane 和 Web of Science。在删除重复文章并应用某些纳入标准后，共选择了 9 篇文章，并使用随机效应模型和逆方差方法进行了对比分析。效应量的显著性通过 z 检验测量，异质性通过 Q 检验和 I² 测量，并使用修剪填充法（trim-and-fill method）分析了出版偏差。

结果： 治疗组与对照组之间的平均差值被估算为效应量，获得的统计显著差异为 -232.01 MPa，95% 的置信区间在 -417.3 和 -44.71 之间（z-检验 = -2.43；p-值 = 0.015）。元分析表现出较高的异质性，I² = 99.3%，Q 检验 = 2,195.7；p-值 Q 检验 = 0.20：p-值 = 0.903，未发现三个亚组之间的显著差异。

结论： 钨钢钻在牙种植体成形术中导致的断裂抗力损失小于钻石和钨钢钻。系统性回顾注册信息: [http://www.prisma-statement.org]，标识符[INPLASY202460018]。
