What is the Role of Piezo Devices in Oral Surgery?

This content is based on the article "Role of Piezo Surgery and Lasers in the Oral Surgery Office" published in Dental Clinics of North America (April 2020)

  • Piezo surgery is a useful adjunct in oral surgical procedures because it helps limit any soft tissue damage secondary to bony surgery.
  • Piezo surgery may limit the amount of sinus membrane perforations during the performance of lateral sinus bone augmentation procedures.
  • Laser surgery has a place in soft tissue and hard tissue cutting procedures, and may also have value in the treatment of nerve injuries and periodontal regenerative procedures.

The term piezo is derived from the Greek word piezein, which means pressure. The process consists of crystals and ceramics that become deformed when exposed to electric flows resulting in oscillating movements with ultrasound frequency that has the power to precisely cut bone structures without causing injuries to soft tissue.

ADVANTAGES OF THE PIEZO TECHNIQUE RELATIVE TO DRILLS AND SAWS

  • Greater precision and safety in bone surgery.
  • Less adverse damages to soft tissues.
  • Less potential for associated bone necrosis.
  • A link flood system that ensures work and comfort of the surgeon by increasing visibility through the cavitation effect—physical effect resulting from ultrasound vibration with water that removes debris from the cutting area.
  • Better healing and reduced postoperative swelling of patients.
  • Different angles permit it to be used in areas where it is difficult to see and reach.
  • The absence of macrovibrations make patients feel comfortable during oral surgery procedures under local anesthesia and intravenous sedation.

DISADVANTAGES OF PIEZO SURGERY

  • This procedure should not be used in patients with pacemakers.
  • The financial cost is a consideration.
  • The duration for procedures tends to be longer.
  • There is a learning curve with its use.
