Acute treatment of a concomitant horizontal root fracture and luxation of the coronal fragment of the right upper central incisor: a case report.

We report a case of a horizontal intra-alveolar root fracture between the middle and apical third of the upper right central incisor associated with an extrusive luxation of the coronal fragment, in a 24-year-old male patient. Twenty minutes after being accidentally hit by a metallic device, the patient's coronal portion was repositioned and splinted under local anesthesia. After that, we lost sight of the patient. One year later, the patient showed up. The splint was lost, the tooth showed physiological mobility and responded to pulp testing. Radiographs showed healing of the horizontal fracture and normal periodontal ligament.
