Tooth loss evokes functional and esthetic problems, and adjacent teeth can move if they are not corrected in a timely manner, rendering the problems of restoring the dentition more complex. If the opposing tooth is consequently extruded, several treatment modalities may be adopted, such as occlusal adjustment, crown prosthesis, orthodontic treatment, and segmental osteotomy. Segmental osteotomy is the most aggressive and invasive treatment for restoring a problematic occlusal plane due to the complications, such as hemorrhage, loss of tooth vitality, or necrosis of the segment. Piezoelectric devices have recently been used in oral surgery and implant dentistry because they preserve the soft tissue. In this report, we describe a bilateral posterior segmental osteotomy procedure to correct a collapsed occlusal plane with sinus mucosa elevation, using piezoelectric devices to preserve the integrity of the sinus membrane and the posterior superior alveolar artery.
