Piezosurgery-Precision in Periodontics and Oral Implantology

Piezosurgery is a relatively new technique of bone surgery that is recently gaining popularity in implantology, periodontics and oral surgery. The piezosurgery instrument, developed in 1988, uses a modulated ultrasonic frequency that permits highly precise and safe cutting of hard tissue. Nerves, vessels, and soft tissue are not injured by the microvibrations (60 to 200 mm/sec), which are optimally adjusted to target only mineralized tissue. 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, with its cutting effect exclusively targeting hard tissue, its use may be extended to more complex oral surgery cases, as well as to other interdisciplinary problems. This article discusses about the wide range of application of this novel technique in periodontology.
