Autotransplantation of Teeth with Complete Root Formation: A Case Series

Introduction: Autotransplantation is a viable option for treating missing teeth when a donor tooth is available. This retrospective study reports the success rate for the autotransplantation of 19 molars with complete root formation. Methods: The study enrolled 19 patients (11 men and 8 women) in whom 19 molars were transplanted. The mean age was 38.5 years (range, 19-67). The transplanted third molars were stabilized with a silk suture or wire splint for 2 to 3 weeks. Root canal treatment of the transplanted teeth was performed before surgery in six patients and 1 to 2 weeks after transplantation in 13 patients. Postoperatively, the marginal and periapical conditions were examined clinically and radiographically. Results: In 16 of the 19 cases, the outcome met the success criteria, for an 84% success rate. Conclusions: In autogenous tooth transplantation, even if the donor tooth has complete root formation, a high success rate can be achieved if the cases are selected and treated properly.
