Abstract

Autotransplantation of teeth is a valuable alternative to dental implants, offering biological compatibility and preservation of alveolar bone. This case report presents two patients who underwent autotransplantation and also discusses the advantages, limitations, and key considerations for successful autotransplantation. A 39-year-old female, received autotransplantation of a left maxillary third molar to replace a non-restorable right maxillary second molar due to fracture. Initially, an implant therapy was considered, but due to the patient’s age and contralateral maxillary third molar’s extraction need, autotransplantation was selected. A 40-year-old female, underwent autotransplantation of a left mandibular third molar to replace a left mandibular second molar lost due to failed endodontic treatment. The process of selecting an appropriate donor tooth, preoperative CBCT imaging, 3D model making, careful extraction, appropriate osteotomy of recipient socket, tooth fixation, and root canal treatment were carefully performed step by step, resulting in successful healing and functional adaptation in both cases.
