The benefits of piezoelectricity in pre-implant surgery

Dental implants are a common solution for replacing missing teeth, but their feasibility depends on the volume of bone available. When bone volume is insufficient, various techniques can be used, such as piezosurgery. The use of piezoelectric devices is increasingly applied in oral surgery. Selective cutting is possible for different ultrasound frequencies acting only in mineralised hard tissue, preserving vital anatomical structures. Using this piezoelectric technique, autogenous bone graft acquisition, osteotomy for expansion of the alveolar bone crest, and maxillary sinus enhancement via the lateral approach can be performed precisely and safely, offering excellent clinical and biological results. The aim of this work is to present the principles of the ultrasonic scalpel, as well as its applications in pre-implant surgery, based on a series of cases carried out by Dr Mohamed Tlili in the External Consultations Department at the University Hospital Dental Clinic in Monastir / TUNISIA.
