title: Biological restoration in a young patient with a complicated crown root fracture with an autogenous tooth fragment.
abstract: Crown-root fractures are one of the most challenging trauma cases to treat. Reattachment of tooth fragment to a fractured tooth being a simple procedure conserves the tooth structure, maintains the natural esthetics value and is thus considered as a favorable treatment option. The reattachment procedure using composite resin should be considered if the subgingival fracture can be exposed to provide isolation after a careful evaluation of the biologic width involvement. This case report presents a complicated crown-root fracture of permanent maxillary left central incisor, involving the biologic width in an 11-year-old boy. The traumatized tooth was treated endodontically and reinforced by using glass fiber-post. Access to the subgingival margins was gained by electro surgery. The fractured fragment was reattached using bonding system and composite resin.
