title: Comprehensive and sequential management of an impacted maxillary central incisor with severe crown-root dilacerations.
abstract: Tooth dilaceration refers to a dental anomaly characterized by an abrupt deviation in the longitudinal axis of tooth. Crown-root dilaceration is diagnosed in teeth with sharp angles at the cement-enamel junction. The greater the bending degree is, the less chance there is for successful teeth preservation and relocation. In this report, a clinical case of an impacted maxillary central incisor with severe crown-root dilacerations was described by means of an operative evaluation using three-dimensional dental computed tomography and a multidisciplinary approach that included surgical, orthodontic, endodontic, prosthetic and periodontal therapy.
