Intrusive luxation of an immature permanent incisor: a 10-year follow-up.

Intrusive luxation in the permanent dentition is rare and considered the most severe form of dental trauma. Intrusion is characterized by the axial displacement of the tooth into the alveolar bone. It normally affects pulpal vitality and the periodontal ligament. The most common forms of treatment are waiting for spontaneous reeruption, repositioning with orthodontic procedures, or immediate surgical repositioning. A well-planned approach to the treatment of an intrusive luxation is necessary to obtain a successful result. This case report describes treatment of an 8-year-old boy who suffered intrusive luxation of his permanent maxillary right central incisor while root formation was incomplete. The patient was followed clinically and radiographically for 10 years.
