Autotransplantation of conoid maxillary third molar in upper incisive site: A reliable aesthetic solution

Abstract

In the management of anterior dental trauma, the maintenance of the traumatized elements has to be preferred, but sometimes this results impracticable. Among different options, autotransplantation provides an adequate therapeutic solution, particularly in crowded arches, in presence of supernumerary elements or when third molars with a root anatomy compatible with the recipient site are available.: This paper presents a case of autotransplantation of a conoid upper third molar (1.8) inside the alveolus of a central incisor undergone at root resorption, after a long time maintenance of the traumatized element 2.1 and different treatments. Furthermore, a comparison of the therapeutic alternatives is proposed. : Due to their root anatomy, premolars and supernumerary monoradiculated teeth are adequate to be transplanted in incisors’ sockets. In the presented case, the presence of a conoid third molar consented the transplantation of the latter, which represented a more conservative treatment than transplanting a premolar. The use of a 3D-printed replica made through a CBCT scan permitted the substantial reduction of the extra alveolar time, avoiding the periodontal ligament contamination and guaranteeing a higher success rate. Due to the complete formation of the donor tooth, root canal treatment was carried out. Autotransplantation represents a valid and biological alternative in the management of traumas of the anterior dental trauma.
