Piezosurgery in oral and maxillofacial surgery.

This review summarizes current knowledge and experience with piezosurgery, a promising, meticulous and soft tissue-sparing system for bone cutting, based on ultrasonic microvibrations. The main advantages of piezosurgery include soft tissue protection, optimal visibility in the surgical field, decreased blood loss, less vibration and noise, increased comfort for the patient and protection of tooth structure. To date it has been indicationed for use in oral and maxillofacial surgery, otorhinolaryngology, neurosurgery, ophthalmology, traumatology and orthopaedics. The main indications in oral surgery are sinus lift, bone graft harvesting, osteogenic distraction, ridge expansion, endodontic surgery, periodontal surgery, inferior alveolar nerve decompression, cyst removal, dental extraction and impacted tooth removal. In conclusion, piezosurgery is a promising technical modality for different aspects of bone surgery with a rapidly increasing number of indications throughout the whole field of surgery.
