title: Rapid orthodontic extrusion using an interocclusal appliance for the reestablishment of biologic width: a case report.
abstract: A multidisciplinary treatment of a case of subgingival fracture in a maxillary anterior tooth is presented. This case report describes a simple method involving an interocclusal appliance and an elastic band for rapid orthodontic extrusion to reestablish biologic width. In addition, a simple technique for surgical recontouring following the coronal displacement of the gingival margin prior to restoration of fractured tooth is explained.
