Piezoelectric surgery or piezosurgery for short, is a process that utilizes piezoelectric vibrations in the application of cutting bone tissue. By adjusting the ultrasonic frequency of the device, it is possible to cut hard tissue while leaving soft tissue untouched by the process. Use of constant irrigation along with the ultrasonic vibrations produces a cavitation phenomenon. The cavitation phenomenon helps to maintain good visibility in the operative field by dispersing a coolant fluid as an aerosol that causes the blood to essentially be washed away. Furthermore, the cavitation effect will bring about hemostasis, which results in a bloodless surgery. Additional benefits is the prevention of “overheating the bone” when the bone is cut. This helps minimize “bone loss” during the cutting of the bone, especially important in harvesting of bone grafts and in dental implant surgery.
The Piezoelectric unit has many applications in Oral and Maxillofacial surgery.
• Separating the tooth roots.
• Hemi-section, root amputation.
• Periodontal surgery.
• Apical resection and endodontic (Root Canal) treatments.
• Dental Implant socket preparation.
• Alveolar ridge splitting and expansion.
• Re-contouring of alveolar crest.
• Mental nerve reposition.
• Preparation of bone window with lateral approach for sinus lifts and atraumatic dissection of sinus mucosa.
• Internal sinus lift floor elevation or Intralift
• Harvesting of autogenous bone grafts.
• Alveolar decortication and corticotomy.
