Autotransplantation is a procedure which transplants teeth from the original position to
other positions in the same individual. It is classified surgical reposition by intraalveolar
autotransplanation and transalveolar autotransplantation. The prognosis for successful
autotransplantation is dependent on a number of factors such as root development,
surgical technique, patient's age, endodontic treatment, time and type of splinting,
preservation of periodontal ligament and storage medium.
The most important factor is preservation of periodontal ligament. The cause of the
failure of transplantation include damage of the transplant during removal from deep
palatal malposition, poor regeneration of the bone around the transplant and chronic
periodontal infection.
In case I, Impacted maxillary canine for which surgical exposure and orthodontic
treatment was impossible was transplanted. After 2 weeks, it showed periapical
radioluency and external root resorption. So, endodontic treatment was done. One year
later, permanent filling was done with gutta percha.
In case II, Transpositioned maxillary central incisor was transplanted after extraction of
impacted mesiodens. Pulp vitality was maintained during 5 months without other clinical
symptoms.
