Fenestration after orthodontic traction of an impacted dilacerated maxillary central incisor: a case report and 4-year follow-up

Dilacerated impacted maxillary central incisors require early detection, early diagnosis, and early treatment. Early orthodontic traction can allow the root, which is confined by the buccal or palatal cortical bone, to rotate along with the crown and enter the cancellous bone, thereby gaining an opportunity for continued development. We reported a case of an 11-year-old boy with an impacted dilacerated maxillary central incisor. Following surgical exposure combined with orthodontic traction, fenestration occurred. However, after four years of follow-up, the affected tooth exhibited normal pulp vitality and no abnormal mobility. This case might offer an indication that even for dilacerated maxillary central incisors with short roots, or those that develop fenestration after traction, the long-term outcomes of traction treatment could be quite favorable.
