The aim of this study was to evaluate whether piezoelectric bone surgery (PBS) for impacted lower third molar extraction reduces the surgical time and risk of intra- and postoperative complications in comparison with conventional rotary instruments. This meta-analysis followed the PRISMA guidelines and was registered in the PROSPERO database. The PubMed, Embase, Scopus, and OpenGrey databases were screened for articles published from January 1, 1990 to December 31, 2018. Selection criteria included randomized controlled trials (RCTs) comparing PBS with conventional rotary instruments for impacted lower third molar extraction and reporting any of the clinical outcomes (intra- and postoperative complications and duration of surgery) for both groups. A risk of bias assessment was performed using the Cochrane Collaboration tool. A meta-analysis was performed, and the power of the meta-analytic findings was assessed by trial sequential analysis (TSA). Strong evidence suggests that PBS prolongs the duration of surgery and low evidence suggests that PBS reduces postoperative morbidity (pain and trismus) in comparison with rotary instruments. Data were insufficient to determine whether PBS reduces neurological complications and postoperative swelling in comparison with burs.
本研究旨在评估与传统旋转器械相比，使用压电骨手术（PBS）拔除下颌阻生第三磨牙是否可以减少手术时间和术中及术后并发症的风险。本荟萃分析遵循 PRISMA 指南，并在 PROSPERO 数据库中进行了注册。从 1990 年 1 月 1 日至 2018 年 12 月 31 日，对 PubMed、Embase、Scopus 和 OpenGrey 数据库进行了筛选，以纳入比较 PBS 与传统旋转器械用于拔除下颌阻生第三磨牙并报告两组任何临床结局（术中及术后并发症和手术持续时间）的随机对照试验（RCT）。使用 Cochrane 协作工具进行了偏倚风险评估。进行了荟萃分析，并通过试验序贯分析（TSA）评估了荟萃分析结果的效力。强有力的证据表明，与旋转器械相比，PBS 延长了手术时间，而低证据表明，与旋转器械相比，PBS 降低了术后发病率（疼痛和牙关紧闭）。数据不足以确定 PBS 是否比涡轮机减少神经并发症和术后肿胀。
