Piezoelectric Surgery
Pronunciation: pee-ay-zoh-ee-LEK-trik SUR-jer-ee
Ultrasonic bone cutting technology that selectively cuts hard tissue while preserving soft tissue.
Full Definition
Piezoelectric surgery utilizes ultrasonic vibrations at frequencies of 25-30 kHz to selectively cut mineralized tissue while leaving soft tissues such as nerves, blood vessels, and mucosa unharmed. This technology offers enhanced precision and safety in oral surgery procedures, particularly in areas with critical anatomical structures. The selective cutting action reduces the risk of nerve damage during procedures like wisdom tooth extraction, sinus lift surgery, and bone grafting. The technology also provides better hemostasis and reduced post-operative swelling compared to conventional rotary instruments.
Usage
Usage note: Often shortened to 'piezosurgery' in clinical documentation.
