Piezo Surgery-an Overview

The bone-cutting technique of the piezoelectric device works due to the use of micro-vibrations at a specific ultrasonic frequency modulated by sonic waves. The sonic and ultrasonic frequency (25-30 kHz) is produced by a mechanical shock wave that vibrates in a linear manner. The cutting tip works with reduced vibration amplitude (horizontal 20-200 mim, vertical 20-60 mim). The selective and thermally harmless nature of the piezosurgery instrument results in a low bleeding tendency. The precise nature of the instrument allows exact, clean, and smooth cut geometries during surgery. Postoperatively, excellent wound healing, with no nerve and soft tissue injuries, is observed. Because of its highly selective and accurate nature, and cutting effect exclusively targeting hard tissue, its use may be extended to more complex oral surgery cases, as well as to other interdisciplinary problems
