Abstract

Dental autotransplantation or autogenous dental transplantation is defined as the surgical removal from one site and insertion in another site of a dental element from one position to another, within the same person. The indications are advanced caries, trauma, agenesis, and severe ectopias. In our case, we tried to provide a therapeutic alternative to an ectopic canine that is very difficult to recover orthodontically, through reimplantation in the correct eruption site. An 11-year-old patient had the left lower canine in mesial ectopic inclusion, difficult to recover orthodontically, with persistence of the deciduous canine in the arch. Autogenous transplantation of the definitive canine was performed in the post-extraction socket of the deciduous canine, in the same operating session, and splinted for 2 weeks. One month and 11 months follow-up, there was absence of mobility, good integration with the periodontal tissues, absence of ankylosis with good representation of the periodontal ligament on the radiographic examination, absence of recessions and/or pathological probing. Tooth auto‑transplantation can be considered an alternative oral rehabilitation approach for some clinical situations. Autotransplantation can be a valid therapeutic alternative in selected cases; however, the high failure rate must be carefully evaluated in the treatment planning phase. It would be desirable to have studies that can provide follow-up for many years and possibly be able to draw up an operating protocol that can provide evidence of correlation with the result.
