Orthodontic extrusion of subgingivally fractured tooth using a removable appliance: An alternative treatment to reestablish biological width

Abstract

Restoration of a traumatically injured tooth presents a clinical challenge for a predictable aesthetic outcome. This case report describes a multidisciplinary approach of a subgingivally fractured permanent maxillary central incisor. A removable orthodontic appliance was used for orthodontic extrusion of root, and surgical gingival recontouring was done with electrocautery to reestablish the biological width. Form and function were restored establishing biological width and esthetics was repaired with porcelain fused to metal crown.
