The oral piezosurgery | [La chirurgia orale piezoelettrica]

The oral piezosurgery 1. Ultrasonic waves have been used for many years in medicine for several diagnostic and therapeutical purposes 2. Modulated ultrasonic frequency are used in oral surgery since the 70ies, but only in recent years bistomorphometric studies have confirmed their advantages in oral and maxillo-facial surgery. 3. Piezosurgery bandpieces allow highly precise and safe cutting of hard tissue (in particular bone), without harming nerves, vessels and soft tissues. The comfort for the patient is better during and after surgical treatment, with a more rapid healing. 4. The difference in time required for surgical procedures between piezosurgery and conventional technique is negligible today. The little more time necessary is repaid by excellent wound healing, reduced patient stress and no soft tissue injuries. 5. The piezosurgery technique is not only a simple alternative to traditional rotating instruments, but also a new technique for germectomy, impacted or ankylosed teeth, maxillary sinus floor lift, crestal bone splitting, intra and extra oral bone grafting (blocks or chips).
