Clinical evaluation of orthodontic treatment after surgical repositioning or transplantation of teeth.

Fourteen impacted teeth in thirteen patients aged 9 to 17 years were either repositioned or transplanted, followed by postoperative orthodontic treatment. Successful results were achieved in twelve of the teeth. In one tooth, ankylosis of the root prevented a successful outcome, and deficient bone healing of the alveolar process led to an unsuccessful result in a second tooth.
