Abstract: 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.
