Tooth autotransplantation is a procedure in which a tooth or tooth germ is transferred from one alveolus to another in the same person. For autotransplantation are third molars, impacted canines, or mandibular premolars are most commonly selected, which have been shown as the best replacement for lost maxillary incisors. The best results are expected if the root of the transplanted tooth has reached between 50 and 75% of its development, and the preservation of a healthy periodontal ligament of the transplanted tooth is extremely important for the success of this procedure. The survival rate of transplanted teeth is high, and the results can be predicted with relatively high certainty. Complications that may occur are pulp necrosis, tooth root resorption, and ankylosis. This method is most often chosen for treatment of young patients because it does not interfere with growth and development and provides satisfactory aesthetic and functional results. The aim of this case report is to present the success of tooth autotransplantation as a possible therapeutic method in the treatment of complications caused by dental trauma. A second mandibular left premolar was transplanted to the site of the trauma affected maxilar central incisor. Two years later, clinical and radiological examination of the transplanted tooth showed no signs of pathology. Pathological mobility was not observed, the gingiva was neat, and the contour of the alveolar ridge was preserved. The patient is satisfied with the aesthetic results and the function of the transplanted tooth. With proper indication setting and surgical technique, tooth autotransplantation is a successful therapeutic method in restoring teeth when prosthetic or implant therapy are contraindicated due to incomplete growth and development of the patient.
