Material and method:

An electronic databases search was performed in PubMed, ISI Web of Knowledge, Science Direct in the last eight years, using the keywords; third molar, osteotomy, surgical instruments, maxillofacial surgery.

Results:

Twenty six articles were selected after applying inclusion and exclusion criteria. Articles that evaluated the perioperative time, facial edema, postoperative pain and amount of analgesics used, were selected, and a common variable in the studies was the longest working time during the procedures performed with piezoelectric devices.

Conclusion:

According to the evidence found, most studies have associated the use of Piezosurgery for extractions of third molars with less facial post-operative oedema. However piezosurgery has a longer greater intra-operative time, which can increase post-operative pain and presence of trismus.
