Abstract: Objective: To evaluate the clinical outcomes of autogenous teeth transplantation(ATT) of third molars in the locations of first and/or second molar areas. Methods: 52 cases were comprised in this review. X-ray examination was performed to evaluate the situations of third molars and tooth space of first or second molars. Third molars were extracted with cautious and underwent root canal therapy without delay. First or secondmolar extraction fresh socket were created, Third molar ATT was performed and fixed with wire.After three months follow-up, clinical outcomes were evaluated.Results: After 3 months to 5 years follow-up, 40 cases of ATT were stable and function well. No periodontal inflammation or root resorptionwere observed. Slight root resorption revealed in 11 cases, and 1 case failed in replantation. Conclusion: Autogenous teeth transplantation of third molars is working in the way of reblacing the lost first or sencond molars.
