A piezo surgical unit is an ultrasonic dental device that precisely cuts bone using high-frequency micro-vibrations while protecting surrounding soft tissues. It consists of a control console, metal handpiece with stainless steel or titanium tips, irrigation system, and foot pedal. It is commonly used in dental implant placement, bone grafting, sinus lift procedures, cyst removal, and other oral surgeries. By minimizing bleeding, improving surgical visibility, and reducing trauma to soft tissues, it promotes faster healing and safer procedures compared to traditional rotary instruments.
