Transalveolar repositioning of an impacted immature permanent mandibular canine.

The purpose of this case report is to discuss the four-year follow-up of a transalveolar transplantation of an impacted immature permanent mandibular left canine. A nine year-old-boy was referred to the dental school because of a mandibular swelling associated with the impacted canine. Under local anesthesia, the tooth was extracted and transplanted in its own space, followed by a two-week orthodontic fixation. The radiographic examination two months later revealed the presence of external inflammatory root resorption, which was treated with an apexification. The overall status of the transplanted tooth and the surrounding hard and soft tissues four years post-treatment indicates a successful outcome.
