Abstract
We report a clinical case of the replantation of impacted maxillary left canine due to an odontoma.The patient had received dental management since infancy in our hospital. Delayed eruption of maxillary left central and lateral incisors had been noted. From the ages of 9 years and 3 months to 11 years and 5 months, retractions of these incisors were performed using the multi-bracket method. At the age of 12 years and 7 months, due to prolonged retention of the maxillary left primary canine,X-ray photographic examination was conducted. A well-delineated radiopaque image was observed near the root apex of the left primary canine. The cusp of impacted maxillary left canine was present near the root apex of lateral incisor. The retraction of maxillary left canine seemed to have difficulty because of its almost completed root formation and the odontoma. At the age of 12 years and 10 months, the odontoma was surgically removed, and the impacted canine was extracted and replanted into the extraction socket of primary canine. Two months after the replantation, endodontic treatment was started. At the age of 14 years and 8 months, restoration with resin-veneered crown was performed.A long single root of the replanted tooth might be advantageous for replantation. Also, in this case,the removed socket of the odontoma was an appropriate size for the replantaion space of impacted tooth. Further, proper aseptic treatment could be done because the replantation tooth was completely impacted. We considered that these situations might contribute to the success of replantation.
