INTRODUCTION: Root dilaceration refers to a dental anomaly characterized by an abrupt deviation in the longitudinal axis of the tooth. It can be localized in the crown, between the crown and the root, or, most frequently, in the root. This report describes a horizontally unerupted maxillary central incisor with distoangular root dilacerations most likely caused by a traumatic dental injury to its primary predecessor. METHODS: Surgical-orthodontic traction was applied after the redistribution of the space in the anterior maxillary region. RESULTS: Root dilaceration of the tractioned tooth was evident and did not allow the alignment of the tooth into proper position in the dental arch. Root canal filling and apicoectomy were performed. This procedure restored the normal appearance of the anterior maxillary teeth. CONCLUSION: Long-term follow-up (8 years) by periapical radiography indicated stable periodontal health without the presence of root resorption.
