[Auto-transplantation of an impacted or retained maxillary canine. Apropos of a case].
Transplantation of an impacted or retained maxillary canine is a common procedure. Bone width at the transplantation site may however be insufficient to accept the transplanted tooth diameter. We describe an original transplantation technique of a high and buccal impacted canine with bone support and gingival transposition. The transplanted tooth remained stable over time and the alveolar profile was normal. Ankylosis and periodontal pocket are observed after healing. Ankylosis was also present before the procedure. The periodontopathy was explained by the lack of periodontal ligament on the distal aspect of the lateral incisor root in front of the canine crown before transplantation. Pocket depth was reduced after periodontal therapy. This technique allows anatomic restoration and an acceptable periodontal environment.
