A new clinical approach for rehabilitation of crown fracture by fragment reattachment - A case report

Maxillary incisors and specifically their crowns are the most common teeth involved in dental trauma because of their anterior positioning in oral cavity and protrusive eruptive pattern. Traumatized anterior teeth require quick functional and esthetic repair. Various treatment modalities have been suggested for complicated crown fractures, however reattachment of the fractured fragment is said to be beneficial in many ways. A 16 year old female patient reported with sports injury to both of her maxillary central incisors and left maxillary lateral incisor. In this case, of complicated crown fracture we used one alternate technique where the fractured fragment was attached onto a glass fiber post (intra-canal anchorage) and then the unit was repositioned in the post space prepared in the root canals using resin luting cement. Reattachment was possible in this case because the fractured fragments were intact and we could achieve a good approximation as the crown and post were inserted as a single unit and thorough curing of the composite was achieved as it was cured extra orally. The whole process was less time consuming and since most of the work was done extra orally maintenance of isolation needed very less time.
