Treatment of complicated crown-root fracture in a single visit by means of rebonding.

BACKGROUND Crown-root fractures of anterior teeth are relatively common but often time consuming and difficult to treat. In some cases, the clinician can complete the treatment in a single visit by reattaching the fractured fragment. CASE DESCRIPTION In this case report, the authors describe the treatment of a complicated crown-root fracture of the maxillary right central and lateral incisors. Among the treatment options for such cases, the treating clinician considered a single-visit rebonding procedure to be the best choice. The treatment consisted of a multidisciplinary approach involving coronal fragment removal, gingivectomy to expose the margins and single-visit endodontic therapy, followed by a rebonding of the fractured fragment by means of prefabricated posts. RESULTS Evaluation at 12 months indicated stable re-attachment of the fragments, good esthetics and good periodontal health. CLINICAL IMPLICATIONS The reattachment of a tooth fragment is a viable, conservative technique that restores function and esthetics, and clinicians should consider it when treating patients with coronal fractures of the anterior teeth.
