Abstract

Injuries of permanent teeth by trauma occur frequently in childhood and adolescence. Crown fractures are as frequent as 25-76% and especially maxillary incisors are prone to fractures. There have been numerous efforts to achieve both aesthetically and functionally satisfying restoration. When a mature tooth is fractured, porcelain crown or laminate veneer could be a choice of prosthodontic treatment. However, in a case of immature permanent incisor fracture, prosthodontic treatment is more complicated due to the immaturity of the tooth. Moreover, if endodontic treatment is accompanied with the prosthodontic treatment, the treatment period is prolonged. In the past, restoration using an orthodontic band, a ready-made crown, or glass ionomer cement did not exhibit esthetically satisfying result. As restorational materials have been improved, now more esthetic restoration is possible by reattaching fractured fragments or light-curing composite resin restoration. We reports cases of patients with fractured maxillary incisors and their successful treatment results through reattachment of fractured fragments and composite resin restoration.
