Interdisciplinary treatment of an impacted dilacerated maxillary central incisor

Abstract

Dilaceration refers to an angular deformity affecting the longitudinal axis of a formed tooth's crown or root. Eruption difficulties are commonly observed in dilacerated teeth, resulting in approximately 50% of them becoming impacted. Treating impacted dilacerated teeth is challenging because of the associated risks of ankylosis, cortical bone penetration, attachment loss, and root resorption. This case report presents an interdisciplinary approach to treating a 9-year-old girl with an inverted impacted maxillary central incisor displaying severe tooth dilaceration. The treatment approach encompassed surgical exposure, orthodontic traction, apicoectomy, root canal filling, and periodontal surgery, aiming to preserve the impacted incisor and reposition it correctly. Favorable outcomes were achieved, characterized by satisfactory occlusion and a healthy periodontium on the completion of treatment. A stable condition was observed during the 6-month follow-up period, with no evidence of root resorption or alveolar bone loss.
