Multidisciplinary management of subgingival crown–root fracture of an immature permanent maxillary central incisor

Abstract

This case report describes the multidisciplinary management of subgingival horizontal crown–root
fracture of an immature permanent maxillary central incisor in a 10-year-old boy. After removal
of the fractured fragment, pulpotomy was performed within 48 h from the injury to promote
apexogenesis. The tooth was orthodontically extruded until the fracture line was located above the
alveolar bone level. Frenectomy, supracrestal fiberotomy, and crown lengthening were performed
after adequate stabilization of the extruded tooth for 5 months. Finally, the tooth was restored
with composite resin by using the acid etch technique. This report highlights that a multidisciplinary
treatment approach with strict cooperation among specialists to manage a complicated crown–root
fracture can save and restore a traumatized immature permanent tooth.
