Transplantation is the transfer of tissue or an organ from one site to another in the same person or between different persons. A transplantation in which donor and recipient are the same individual has been termed as autogenous transplantation, autoplastic transplantation, or autotransplantation. The purpose of this report was to describe a patient undergoing auto transplantation of an impacted mandibular canine to its normal position in the dental arch and the 1 1/2-year follow-up, with no sign of active inflammatory resorption or a periapical lesion. In addition, there was no sign of replacement resorprion (ankylosis). The endodontic literature has shown that the prognosis of patients undergoing autotransplantation may be good under specific considerations. Therefore, the technique may be a treatment option for the replacement of missing teeth whereever applicable.
