The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on soft tissue and bone healing. Material and methods: This study was carried out as a randomized controlled clinical trial; split mouth design. Ten patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction, were treated randomly using either the piezosurgery or the conventional bur technique on each side. Duration of the procedure, postoperative edema, trismus, pain, healing, bone density and quantity were evaluated up to 6 months postoperatively. Results: Test and control sites were compared using paired t- test. There was statistical significance in reduction of pain and swelling in study groups, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test group showed better results. Conclusion: Piezosurgery technique improves postoperative healing, bone quality within the extraction socket, bone quantity along the distal aspect of the mandibular second molar and offers better quality of life for patients. Key Words: Piezosurgery, impacted wisdom, postoperative complications.
