Piezosurgery dental1/6/2024 ![]() ![]() They are available in different sizes and shapes with titanium or carbide coating. Various types of headpiece tips including scalpel, saw, cone compressor, bone harvester etch are available. Holders for the headpiece and irrigation fluids.įoot switch which activates the handpiece tips. MechanismĬontrol unit to control the frequency of vibrations, power of cutting and the amount of irrigation. The addition of a 50 kHz pulse every 10 ns to this basal frequency increases the power of the receiver device allowing the bone cutting without damaging soft tissues. Usually it produces a functional frequency of 20 kHz as in ultrasonic scalers. The tip on the bone tissue with slight pressure generates a mechanical cutting effect called cavitation phenomenon. The periodic changes in the polarity of field produces ultrasonic oscillations, which are amplified and transferred to a vibration tip to diverse solid, liquid or gaseous materials. The crystals in the piezoelectric substances get deformed when it is placed in an electric field. The piezosurgery works on the principle of piezoelectric effect which is based on cavitation effect and microvibration phenomenon. The soft tissue sparing capability with improved patient comfort and decreased blood loss gave the utmost importance for this surgical technique in the present as well as future world of surgery. The application of this meticulous technology is increasing in various surgical fields like otorhinolaryngology, neurosurgery, maxillofacial surgery, ophthalmology, traumatology and orthopaedics. Various studies gave the evidence of improved wound healing and bone formation compared to conventional approaches. Later in 2000 Italian oral surgeon Tomaso Vercellotti developed the new technique of piezosurgery to overcome the limits of traditional instrumentation in oral bone surgery by modifying the conventional ultrasound technology. The principle of piezoelectric effect was first described by the French physicists Jean and Marie Curie in 1880. It works on the principle of ultrasonic microvibrations. Piezosurgery is a recently advanced surgical technique for sectioning the hard tissues sparing the adjacent soft tissues such as brain, neurovascular structures and mucosa.

Conclusion: Piezosurgery has emerging as a promising surgical modality with a wide range of clinical applications throughout the whole field of surgery. Corpus: It works on the principle of piezoelectric effect in which crystals in the piezoelectric substances get deformed on the application of an electric field. ![]() * Correspondence: Piezosurgery is an emerging boom in the field of maxillofacial surgery for precise, safe and effective osteotomies sparing the adjacent vital structures compared to conventional surgery.
