Abstract

<p>We retrospectively studied the cases of 32 patients who received autotransplantation of third molars with complete root formation at Osaka Dental University Hospital from April 2013 to March 2018. Age, sex, recipient site, donor tooth, transplantation method, duration of observation, and postoperative course were elicited from patient clinical records. The subjects were 4 males and 28 females with an average age of 39 years. A mandibular first molar site was the most common recipient (25% for each side) and the mandibular left third molar was the most common donor (41%). Immediate transplantation was the most common transplantation method (78%). The one-year survival rate was 96.9%, while the three-year rate was 85.7%. Only one transplant tooth (3.1%) was lost one month after the operation because of a failure of wound healing. Only 4 cases (12.5%) were detected with a periodontal pocket of more than 4mm around the transplanted tooth. The survival rate for autotransplanted third molars with complete root formation at our hospital is high. Tooth autotransplantation is a valuable treatment for recovering the occlusal function of missing teeth. Shika Igaku (J Osaka Odontol Soc) 2020; Oct; 83(2):76-82.</p>
