title: Reattachment of an autogenous tooth fragment in a fracture with biologic width violation: a case report.
abstract: An 11-year-old patient that fractured her maxillary left central incisor is presented. The fracture involved two thirds of the crown, compromising the pulp, and extended subgingivally on the palatal aspect, invading the biologic width. The procedure used to repair the fracture included flap surgery with a slight ostectomy and endodontic treatment. The reattachment of the tooth fragment and the restoration were performed with a bonding system and a resin composite. Examination 6 months after treatment revealed periodontal health, good esthetics, and normal function.
