Chin bone graft and sinus membrane elevation using Piezosurgery : Case reports

Piezosurgery uses modulated ultrasonic vibration to allow controlled cuting of bony structures. delicate bony structures can be cut easily and with great precision without destruction of soft tissue. Piezosurgery can be used to harvest the chin bone for intra-oral augmentation. Maxillary sinus membrane perforation is the most common complication that occurs with the sinus elevation augmentation procedure. This complication can occur during the osteotomy, which is performed with burs, or during the elevation of the membrane using manual elevators. The purpose of this study is to introduce new surgical technique that simplifies chin bone graft and maxillary sinus surgery, thus avoiding perforating the membrane.
