Piezoelectric bone surgery is a process that utilizes piezoelectric vibrations in the application of cutting bone tissue. The process was patented by Fernando Bianchetti, Domenico Vercellotti, and Tomaso Vercellotti. It was first used clinically in 1988. It is indicated for use in oral, maxillofacial, cranial and spinal procedures; but is mainly used in orthodontics and craniofacial surgery.
