Ostectomy versus osteotomy with repositioning of the vestibular cortical in periapical surgery of mandibular molars : a preliminary study

2010

Introduction: Accessing the tooth roots in periapical surgery (PS) requires the elimination of periapical bone. Objective: To compare the postoperative morbidity and prognosis following PS on mandibular molars by ostectomy, or by osteotomy with repositioning of the vestibular cortical. Material and Methods: A retrospective clinical study of mandibular molars subjected to PS with ultrasound. Two groups were considered according to the surgical procedure used to access the roots: Group 1 (G1) with ostectomy and Group 2 (G2) with osteotomy and repositioning of the vestibular cortical. Only patients who had properly followed the post-operative instructions, adequately completed the post-operati…
