Comparing Piezosurgery and Rotary Techniques in Direct Maxillary Sinus Lifting

Abstract

Background: Sinus lifting is a common surgery for bone loss in the posterior part of the maxilla. It facilitates inserting prostheses and rehabilitating the edentulous posterior maxilla. If the alveolar bone remains less than 5 mm, direct sinus lifting using the rotatory handpiece is used to perform the lateral window approach. Objective: To compare piezosurgery and rotary techniques in direct sinus lifting. Methods: A cross-sectional study was conducted from October 2022 to August 2023. We enrolled 15 patients, ranging in age from 45 to 66 years, who required bilateral direct sinus lifting. Piezosurgery was performed on one side, while rotary surgery was performed on the other. We assessed the intraoperative time of opening the bony window, as well as the postoperative pain, swelling, and mouth opening at 1 hour, 2 days, 7 days, and 1 month after the procedure. Results: With rotary tools, the time for opening a bony window was significantly shorter. Piezosurgery resulted in significantly less swelling after 2 days, but there was no significant difference between the two groups after 7 days and 1 month. Regarding mouth opening, the piezo group yielded a significantly larger difference after 2 days, but the two groups demonstrated no significant difference after 7 days and 1 month. Regarding pain, the piezo group demonstrated a lower score after 6 hours and 2 days, but the two groups demonstrated no significant difference after 7 days. Conclusions: Postoperatively, piezosurgery for sinus lifting leads to less pain, swelling, and limited mouth opening.
