ABSTRACT=This case report presents the use of dental autotransplantation, a procedure in which a donor tooth is transferred to a recipient site in the same patient, improving functional and esthetic characteristics. The advantages of this technique compared to conventional prostheses and surgical treatments, such as dental implants, are discussed. A 27-year-old patient with no relevant medical history was evaluated for pain and discomfort in fractured teeth with previous endodontic treatments and odontogenic sinusitis. A non-restorable maxillary first molar was diagnosed and extracted and replaced with a previously endodontically treated maxillary third molar, for which a 3D-printed replica was used to reshape the alveolar site. The intervention was successful, after which an adequate clinical and radiographic follow-up was carried out for 3 years, showing good bone formation and continuity of the periodontal ligament, with no signs of pathological resorption. This case demonstrates that, when properly planned and executed, dental autotransplantation can be an effective and biological alternative for dental rehabilitation, especially with the use of advanced technologies, such as cone beam computed tomography and 3D-printed replicas of donor teeth.
