Use of new piezoelectric inserts in the avulsion of complex impacted teeth

Abstract

This case series aims to present a new method for the avulsion of impacted third molars with a high risk of nerve damage.This new technique uses piezoelectric surgery, particularly the new dedicated insert, in order to significantly reduce the risk of iatrogenic injury induced by levers and rotating instruments. The study examines 17 dental elements with different degrees of impaction, classified according to Winter's Classification and Pell & Gregory's Classification. Therefore, the prediction of the intervention difficulty was evaluated using the Modified JD Classification (MJD). When performing surgical extractions of teeth located near the inferior alveolar nerve (IAN), there is a considerable risk of neurological complications, in all the cases presented, the patients had a normal postoperative course, without any septic or functional/neurological complications. In cases where continuity with noble structures represents a strong risk factor for neurological sequelae, this technology can greatly reduce the risk of iatrogenic injuries.
