What Is Piezosurgery?

Piezosurgery is a New Frontier in Dental Surgery.  It is a new bone cutting technique that involves the use of ultrasonic waves — now becoming standard in the dental office. An increasing number of dentist and surgeons are adopting the method, as they find it harmless and safer and less invasive than traditional motorized or manual approaches.

Piezosurgery is a  handheld device that generates ultrasonic micro-vibrations to safely and precisely leaving soft tissues untouched, cuts through bone with impressive precision avoiding soft tissue altogether. It is being used in dental applications, including oral surgery, periodontics, and implantology.

How Does Piezosurgery Work?

Piezoelectricity is a fascinating form of electrical energy. It generates when crystals, such as quartz, are “pressed” or subjected to mechanical stress. As an effect, electricity flows. The crystal has a positive charge and a negative charge.  When two faces are connected, the current flows to create an electrical circuit. The energy produced by this piezoelectric effect is harnessed.  Then the device called a piezoelectric transducer turns into other forms of energy, such as ultrasound. These ultrasonic waves can then be increased and converted into faster-automated vibrations.  The devise tip vibrates within a range of 60–200mm, which enables the dentist to cut through bone cleanly with high precision while the handpiece is fortified with a sterile irrigation system.  An LED light for thoroughgoing visibility and safety is also there.  The power emitted from the ultrasound could be adjusted according to different types of bone density.

Three Main Modes of Piezosurgery:

  1. For root canal treatments, low mode is the most appropriate.
  2. High mode is used for cleaning and smoothing out bone borders.
  3. The boosted mode is often used in oral and maxillofacial surgery for osteoplasty and osteotomy procedures

Is Piezosurgery Better Than Traditional Bone Cutting Methods?

Dental surgery traditionally with manual cutting devices involves manipulation or reshaping of the bone, which is performed by manual instruments like the bone chisels and other tools like the rongeurs. Sometimes powered rotary instruments like the rotary burs and oscillating saws are also used. Manual cutting devices usually are used for rough-cutting more significant segments of bone which are more challenging to control when precision is necessary. They can cause microfractures and damage the bone or surrounding soft tissue. Postoperative inflammation and bleeding may occur, and this can slow down healing, this can be stressful for the patient

Piezosurgery represents a significant improvement than the techniques mentioned above.

Piezoelectric devices are ultrasonic device that aids the micrometric cutting of bone and greater precision with no bone loss. It is unusually light and easy to handle and to cut across a flat plane or in a curvilinear fashion from side to side.  The surrounding soft tissue remains intact and no bleeding, which in turn improves visibility of the operation site. Less collateral tissue damage and bleeding also mean not as much swelling.  Ultrasonic vibrations benefit stimulating cellular metabolism. The absence of dead tissue in the cut area accelerates bone regeneration. The device produces significantly less noise than motorized equipment and requires no applied pressure, reducing psychological fear and distress to the patients.

Advantages of Piezosurgery

Piezosurgery was made to meet the demand for better safety, well-being, and exactness in the bone surgical procedure. Piezosurgery minimizes any pain to the blood vessels, nerves, and mem
