The bone cutting was performed using manual or motorized instruments. Hand instruments are primarily used to remove small amounts of bone but are difficult to control in cortical bone. When the bone is dense, powered instruments are often used. Powered instruments transform electrical energy into a mechanical cutting action, so there will be overheating of the surrounding tissue which may delay the healing response. Then the role of peizosurgery comes into action. Most dental implants are placed using a drilling surgical technique. However, dentistry has recently experimented with the implementation of piezoelectric surgery. This technique was introduced to overcome some of the limitations related to rotary instruments in bone surgery. This technique was born and developed in response to the need to achieve greater levels of precision and safety in bone lesions, compared to what can be obtained from the usual manual and motorized instruments.

The device is characterized by piezoelectric ultrasonic vibrations with a frequency of 29kHz and a range between 60/200 Hz. Due to their characteristics, the microvibrations allow selective cutting of only the mineralized structure without damaging the soft tissues, which remain intact even in the event of accidental contact . It also maintains a clear surgical site which is the result of the cavitation effect created by an irrigation/cooling tool and an oscillating tip. Micrometric vibration ensures precise cutting action. The micrometric vibration makes the instrument easy to handle and allows greater interoperative control with a consequent increase in safety especially in anatomically difficult areas. The piezosurgical inserts do not overheat, preventing the risk of postoperative necrosis and promoting rapid healing. The coolant flows in a laminar fashion along the tip. In this way, more effective cooling is achieved even in the deepest regions. The applications of piezosurgery are quite extensive in dentistry and include retrograde preparation in the root canal, bone cutting with great precision facilitating ridge augmentation and expansion. In periodontal procedures, careful removal of small amounts of bone adjacent to exposed root surfaces is necessary to avoid damaging the tooth surface. Piezosurgery plays a positive role in the development of the physiological bone-supporting architecture of the affected teeth. The main use of the piezosurgical device is in implantology which includes the preparation of the implant site, removal of the implant and bone harvesting, bone grafting and sinus lift which can be performed very easily and with less trauma than soft tissues. Methods such as ridge expansion, sinus elevation, harvesting of bone fragments and bone blocks are becoming much safer and easier. Please note: this is just an example.
