Piezosurgery is a new technique that can be used to cut mineralized structures without damaging adjacent soft tissues. This device has a lot of advantages: reduced surgical time, blood loss, and inferior alveolar nerve injury in bimaxillary osteotomy. Fifty patients underwent different surgical operations (orthognathic surgery, traumatic surgery, reconstructive surgery, aesthetic procedures) with 7 different kind of piezosurgery inserts in a period of 8 months. The same two surgeons performed all the procedures. All the procedures were carried out in order to improve the precision of the osteotomy and the comfort of the surgeon. Piezoelectric devices provide an innovative ultrasonic technique for safe and effective osteotomy compared with methods that use rotating instruments. Different inserts have been developed in order to achieve the utmost advantages.
