title: Management of an unerupted dilacerated maxillary central incisor after trauma to the primary predecessor.
abstract: The most common cause of permanent maxillary incisor dilaceration is usually trauma to the primary predecessor, such as avulsions, intrusions, or gross displacement of primary incisors. The purpose of this case report was to describe the surgical exposure and orthodontic traction of  an unerupted dilacerated permanent maxillary central incisor performed on a young girl. During the surgical exposure, a hole was placed in the tooth crown, and elastic chains, inserted though the hole, were used for traction. The alignment and leveling of the impacted incisor were performed  with sequential stainless steel wires. Good periapical and periodontal health, combined with adequate occlusion and a positive esthetic outcome, demonstrated the satisfactory results of this case.
