Crown fragment reattachment: report of an extensive case with intra-canal anchorage.

This paper describes the resolution of an extensive complicated crown-root fracture of an endodontically treated maxillary central incisor. Initially, the fractured crown was splinted to the adjacent teeth with orthodontic wire and composite resin. Subsequently, the crown fragment was reattached by means of a fiber post using a hybrid composite resin. Early stage success was achieved with the observance of normality in function, esthetics, and health of the tooth and surrounding periodontal structures. An athletic mouthguard was fabricated to prevent further trauma. Advantages, disadvantages, and prognosis of the treatment presented are discussed.
