Ultrasound tooth extraction in dentistry is called piezosurgery. A special device called a Piezotome acts on bone fragments with ultrasonic waves. As a result, a kind of "scalpel"is formed. It has a pinpoint effect on the operated area, while not affecting healthy tissues. During the procedure, the operated area is cooled. The cooling agent is carried out in parallel jets along the tip due to vibrations. Compared to conventional rotating tools, the piezoelectric scalpel allows for efficient cooling even in deep layers. Despite the advantages of the method, piezosurgery is usually used for complex extraction. However, at the request of the patient, any teeth are extracted using the device. The method is often recommended for children, as it practically does not cause pain and bleeding.
