Autotransplantion of a displaced mandibular second premolar to its normal position.

ABSTRACT

The patient was a 13-year-old Korean girl who had a displaced mandibular second premolar. She was reluctant to undergo a lengthy orthodontic treatment and opted instead for transplantation of the premolar to its usual site. On the basis of computed tomography, a replica tooth model was manufactured to shorten the extraoral time, and a root canal treatment was performed because root formation was complete. No negative signs or symptoms were found during a 3-year follow up. Autotransplantation for this patient obviated the need for orthodontic traction and prosthetic therapy.
