All-on-4种植修复中倾斜种植体与轴向种植体失败率及边缘骨丧失的比较：meta分析

Abstract

Abstract: Objective　To compare the implant failure rates and peri-implant marginal bone loss(MBL) of tilted implants and axial implants in All-on-4 treatment concept after over 3-year follow-up. Methods　An electronic search was undertaken in PubMed, Web of Science and Cochrane Library with the searching time from the establishment of the database to August 2019. An additional manual search of the related reviews was also undertaken. After study selection and data extraction, a meta-analysis was conducted. The primary outcome was implant failure rates and the secondary outcome was MBL. Results　Twelve studies meeting the criteria were included. There was no significant difference in implant failure rates(RR=1.24, 95% CI:［0.85, 1.83］, P=0.27) between tilted implants and axial implants in All-on-4 treatment concept. In terms of MBL, meta-analysis showed that no significant difference was found between tilted implants and axial implants(MD=-0.02, 95% CI:［-0.07, 0.03］, P=0.47). Conclusion　After over 3-year follow-up, tilted implants and axial implants in All-on-4 treatment concept might have similar implant failure rates and peri-implant marginal bone loss. More high-quality studies with larger sample size and longer follow-up are needed to support our findings in the future.
