Multidisciplinary and esthetic approach to clinical crown lengthening: Report of a case
Ngan / Knobloch
This paper describes the combined efforts of an orthodontist periodontist, and a restorative dentist to save an unrestorabl e tooth by clinical crown lengthening. A maxillary lateral incisor, originally treatment planned for extraction, was treated with orthodontic extrusion, circumferential fiberotomy, and metal-ceramic crown restoration. To maximize the esthetic appearance of the tooth during orthodontic treatment, an acrylic resin facing was designed together with the orthodontic appliance used to facilitate vertical extrusion. Clinical crown lengthening may be used as an alternative approach to the treatment of severely broken down anterior teeth.
