The present study aimed to evaluate and compare the postoperative effects of the piezoelectric device and conventional rotary instruments in Schneider's membrane sinus lifting procedure.
Twenty patients requiring bilateral maxillary bone graft augmentation in the posterior maxillary region were selected. Piezoelectric surgery was performed on one side and conventional surgery with a rotary diamond bur on the other. Postoperative pain, swelling, edema, and mouth opening were evaluated at one hour and two and seven days after the procedures. All variables were submitted to Friedman or Wilcoxon tests at a 5% significance level.
The comparison between groups showed that postoperative pain after one hour and two days was significantly lower (< 0.05) in the piezoelectric device group. Regarding the edema, the results of both techniques were similar at all times assessed (> 0.05). Piezosurgery was statistically associated (< 0.05) with greater mouth opening only at the 48-hour evaluation.

本研究旨在评估和比较压电装置与传统旋转器械在施奈德膜窦提升术中的术后效果。
选取20例需要对上颌后牙区双侧进行骨增量的患者。一侧采用压电手术，另一侧采用旋转金刚砂车针进行传统手术。在术后1小时、2天和7天评估术后疼痛、肿胀、水肿和张口度。所有变量均在5%显著性水平下进行弗里德曼检验或威尔科克森检验。
组间比较显示，压电装置组术后1小时和2天的疼痛明显较低（<0.05）。关于水肿，在所有评估时间点两种技术的结果相似（>0.05）。仅在48小时评估时，压电手术与更大的张口度存在统计学关联（<0.05）。
与传统技术相比，使用压电装置进行截骨术后疼痛较轻，张口度更大。压电手术、窦提升、水肿、疼痛、旋转器械。
