Various osteotomy instruments have been introduced in recent decades for use in the medical and dental fields. Among them, piezoelectric bone surgery (PBS) is an alternative to conventional rotary instruments that enables precise osteotomy with minimal soft-tissue damage during the healing period1. PBS can also reduce postoperative edema and ecchymosis compared to lateral osteotomy immediately after surgery.PBS has also been widely used when performing osteotomy associated with ridge and sinus augmentation. Mucosal perforation during lateral window preparation can lead to severe complications such as poor bone regeneration, high implant failure, and sinusitis1. Because lower rate of mucosal perforation is reported in many studies, PBS is commonly used when crestal and lateral sinus elevation is performed. In addition, the lateral bony window created by the piezoelectric saw insert is repositioned precisely and also acts as an osteoinductive/osteoconductive substrate in the maxillary sinus in bone grafted/non-bone grafted sinus2. On the other hand, collagen barrier has no effect on bone regeneration. The use of the PBS makes it possible to create a lateral bony window without injury to the intraosseous artery because of microvibration and selective cutting3. High-speed surgical instruments can influence the probability of membrane perforation due to the limitations of anatomical structures of the sinus cavity. However, piezoelectric devices, with their pen grip, can easily be used in the deep oral cavity.Compared to conventional rotary instruments, PBS demonstrates higher bone cell viability and precise osteotomy. Therefore, PBS is considered a valid alternative to rotating burs when performing osteotomy for autogenous bone harvesting, removal of impacted teeth or cysts, distraction osteogenesis, other augmentation procedures, and cosmetic bony surgery. PBS is beneficial when immediate implant placement is performed because it provides bactericidal curettage in the extracted sockets with chronic inflammation. The benefits of PBS overcome its disadvantages such as slow cutting, and therefore its use is recommended for hard tissue dental and oral and maxillofacial procedures.
