Abstract

Purpose

Piezoelectric surgery is a safe and effective osteotomy technique that can decrease the perioperative complications and morbidity in oral-maxillofacial surgery. In this study, we compare piezosurgery and conventional rotary technique in the removal of impacted lower third molars. Our primary end points were perioperative anxiety, pain and postoperative discomfort while avoiding the drilling sound of the conventional instrument.

Materials and Methods

Twenty one patients (14 female, 7 male) with bilateral symmetrical impacted lower third molars were included in our study. The two osteotomy techniques were randomly allocated to be performed on the right or the left impacted lower third molars. The parameters evaluated were perioperative anxiety (STAI), postoperative pain (VAS), operation time and paresthesia.

Results

No significant difference was seen between piezosurgery and conventional rotatory techniques in terms of pain, anxiety and nerve damage. Preoperative anxiety was significantly higher in the female group than in the male group. No correlation was found between preoperative anxiety and postoperative pain. Operation time was found to be significantly longer in the piezosurgery group.

Conclusion

Piezosurgery provides a precise, less agressive osteotomy compared to conventional rotary techniques. However, it has not been found to significantly reduce perioperative pain and anxiety.
