Abstract
|
|
|
|
Supernumerary tooth is developed from overgrowth of dental laminar and is mainly observed in the maxillary anterior area, named ’mesiodens. Mesiodens cause many problems such as malposition of permanent anterior tooth, diastema, formation of cyst, and eruption to oral or nasal cavity. Extraction, therefore, is generally recommended choice of treatment. This case report describes that the patient is a 9 years and 8 months old boy, whose unilateral maxillary incisor was missing due to trauma, and he had a mesiodens. We practiced autotransplantation of the mesiodens to the missing maxillary central incisor area and then restored with prosthetics, substantially kept out alveolar bony resorption and provided esthetic appearance. Mesiodens was too small to be used as an abutment because its length is totally 14mm, so that poor prognosis was anticipated due to bad crown/root ratio. However, we observed clinically acceptable result during the observation period of 8 months after operation.
