The Department of Periodontology is involved in performing cases with Piezosurgery. It is a new method that uses piezoelectric ultrasonic vibrations to perform precise and safe osteotomies. It was first discovered by Tomaso Vercelotti to overcome the limitations of traditional instruments in oral bone surgery. Its use was first introduced in the field of preprosthetic surgery alveolar crest expansion and sinus grafting procedures. It is a favorable, scrupulous, and soft tissue sparing system for bone cutting based on low frequency ultrasonic microvibrations. The absence of macrovibration makes the instrument more feasible and allows greater intraoperative control with increase in cutting safety in the more difficult anatomical cutting zone.Few years ago, ultrasonic dental instruments were exclusively utilized for scaling and root planing. In the 1980's use of devices employing ultrasonics were well known for odontostomatologic surgery. The attempts using ultrasonics equipment in bone surgery showed good results in the cutting phase.
