Ultrasonic bone surgery, also known as piezoelectric ultrasonic bone surgery, is a surgical technique using an ultrasonic device operating at a modulated frequency. It is designed to cut or grind bone but not damage any of the adjacent soft tissues. An ultrasonic bone surgery system provides an efficient way to deal with cutting during oral procedures. This surgical technique allows for the safe completion of more complex procedures. An ultrasonic bone surgery unit works by creating ultrasonic waves within a specific frequency range. These waves cause a deformation of piezoceramic rings which in turn, causes sets of vibrations to take place in an amplifier. These waves are then transmitted to a handpiece which cuts through bone tissue by shattering it on a microscopic level. This process has made many types of dental procedures less traumatic for patients, with less surrounding soft tissue damage, while also improving the healing process.
