The Effect of Piezoelectric Use on Open Sinus Lift Perforation: A Retrospective Evaluation of 56 Consecutively Treated Cases From Private Practices

摘要: Background: The lateral window approach to maxillary sinus augmentation is a well-accepted treatment option in implant dentistry. most frequent complication reported with traditional techniques has been the perforation of Schneiderian membrane, rates ranging from 11% 56%. purpose this retrospective, consecutive case series two private practices was report on rate membrane perforations and arterial lacerations when piezoelectric surgical unit used conjunction hand instrumentation perform elevations. Methods: Clinical data (Schneiderian perforation, Underwood septa, laceration blood supply sinus) were obtained retrospectively pooled for analysis. information collated after an exhaustive chart review. Fifty-six consecutively treated lifts performed 50 partially or completely edentate patients. Results: Zero occurred during preparation antrostomies, whereas noted subsequent elevations using instrumentation. In both instances, associated septa. overall 3.6%. Arterial branches posterior superior alveolar artery encountered 35 cases, there zero instances laceration. Conclusions: This retrospective clinical confirmed that elevation incorporating technology effective means achieve while minimizing potential intraoperative complications. Further prospective randomized controlled studies are warranted qualify these observations. J Periodontol 2010;81:167-171.
