The aim of this systematic review was to assess the primary and secondary stability of dental implants placed at sites prepared with piezoelectric bone surgery (PBS) and conventional drilling (CD). The PubMed/MEDLINE and Cochrane Library databases were searched without date or language restriction up to June 2017. Controlled clinical trials in which each patient received implants placed at sites prepared with both PBS and CD were selected. Implant stability had to be measured on day 0 and during the osseointegration period. Methodological quality was assessed using the Cochrane Collaboration tool. A meta-analysis was performed to compare primary stability (on day 0) and secondary stability (after 2 and 3months) between the two groups. The studies included were determined to have a high risk of bias. There was no significant difference between the two groups for primary stability (on day 0) (P=0.51). After 2 and 3months, secondary stability was statistically higher in implants placed with PBS preparation (P=0.04 and P=0.01, respectively). The implant survival rate was 97.5% in the CD group and 100% in the PBS group. PBS preparation improves secondary stability after 2 and 3months in comparison to CD, with similar implant survival rates. Further studies are needed to determine whether implant osseointegration periods could be shortened with PBS preparation.
本系统评价的目的是评估在采用压电骨手术（PBS）和传统钻孔（CD）制备的部位植入牙种植体的初期稳定性和二期稳定性。检索了截至2017年6月的PubMed/MEDLINE和Cochrane图书馆数据库，无日期或语言限制。选择了对照临床试验，其中每位患者在采用PBS和CD制备的部位均植入种植体。必须在第0天和骨结合期测量种植体稳定性。使用Cochrane协作工具评估方法学质量。进行荟萃分析以比较两组之间的初期稳定性（第0天）和二期稳定性（2个月和3个月后）。纳入的研究被确定存在高偏倚风险。两组之间的初期稳定性（第0天）无显著差异（P=0.51）。2个月和3个月后，采用PBS制备植入的种植体二期稳定性在统计学上更高（分别为P=0.04和P=0.01）。CD组的种植体存活率为97.5%，PBS组为100%。与CD相比，PBS制备在2个月和3个月后可提高二期稳定性，种植体存活率相似。需要进一步研究以确定PBS制备是否可以缩短种植体骨结合期。
