Piezosurgery in Periodontics

Abstract

ABSTRACT Piezosurgery is a new and innovative method that uses piezoelectric ultrasonic vibrations to perform precise and safe osteotomies. It was first invented by Tomaso Vercelotti to overcome the limitations of traditional instruments in oral bone surgery. Its use was first reported in the field of preprosthetic surgery alveolar crest expansion and sinus grafting. It provides substantial improvement dental/implant surgery, benefiting the surgeon by ease of use and the patient by minimizing surgical trauma and promoting rapid healing. Manual is used to remove small amounts of bone in areas with relatively less dense mineralization. The manual instruments are difficult to control in cortical bone, particularly where precise osteotomies are essential. They are mostly applied for gross cutting of large bone segments. Motor Driven instruments are often used when bone is very dense. Motor driven instruments transform electric or pneumatic energy into mechanical cutting action using the sharpened edge of burs or saw blades. These instruments generate a significant amount of heat in the cutting zone that must be minimized by water irrigation overheating of adjacent tissue may alter or delay the healing response. The reduced rotational speed decreases not only frictional heat but also cutting efficiency. Motorized cutting tools also decrease tactile sensitivity, slower rotational speed necessitates increased manual pressure which increases the macro-vibration of the cutting tool and further diminishes sensitivity. This article discusses about the wide range of application of piezoelectric technique. How to cite this article Devi S, Swaminathan M, Karthikeyan I, Anitha K. Piezosurgery in Periodontics.
