摘　　要：目的：探讨超声骨刀在开窗式上颌窦底外提升术中应用的临床效果及安全性。方法：对29名患者30侧行上颌窦底开窗式外提升术，用超声骨刀开窗，植入种植体共53枚（同期植入47枚，延期植入6枚），6～8月后完成上部修复。修复后3、6及12个月复查。结果：术前平均剩余牙槽突高度为4．46mm，术后平均提升高度为7．34mm，植入53枚植体，没有发生黏膜穿孔。术后随访3～18个月没有发生种植体周围炎、种植体周围黏膜炎及种植体松动脱落。X线片显示种植体周围骨结合良好。种植体存留率及手术成功率均为100％。结论：超声骨刀在上颌窦底开窗式外提升术中安全可靠。Objective：To evaluate the clinical effect and safety of piezoelectric osteotomy in lateral sinus floor augmentation.Meth-ods：53 implants were placed in 30 sites after lateral sinus floor augmentation（LSFA）in 29 patients by piezoelectric osteotomy.47 implants were placed simultaneously with LSFA,6 were delayed.6-8 months after implantation,the final fixed prostheses were per-formed.The patients were followed-up at 3,6,and 12th months after restoration.Results：The mean residual bone height（RBH） was 4.46 mm before operation.The mean height of sinus elevation was 7.34 mm after operation.No membrane perforation occurred. Peri-implantitis,peri-implant mucositis and implant mobility were not found during follow-up.X-ray examination showed good os-seointegration in the interface between the implants and bones.The implant survival rate and the operation success rate were 100%. Conclusion：The application of piezosurgery is safe and reliable in lateral sinus floor augmentation.
