After removalof the fractured fragment, pulpotomy was performed within 48 h from the injury to promoteapexogenesis. The tooth was orthodontically extruded until the fracture line was located above thealveolar bone level. Frenectomy, supracrestal fiberotomy, and crown lengthening were performedafter adequate stabilization of the extruded tooth for 5 months. Finally, the tooth was restoredwith composite resin by using the acid etch technique. This report highlights that a multidisciplinarytreatment approach with strict cooperation among specialists to manage a complicated crown–rootfracture can save and restore a traumatized immature permanent tooth.Key Words: Complicated crown–root fracture, immature incisor, traumatized toot
