Surgical extrusion to provide a ferrule for restoring a tooth with a compromised prognosis: A clinical report.

A surgical extrusion technique was used to provide a ferrule for a tooth with significant tooth structure loss and an oblique coronal fracture. The maxillary lateral incisor was surgically repositioned coronally to provide sufficient dentinal wall for a good prognosis of the restorative treatment. The procedure is conservative and relatively straightforward and can be performed rapidly with minimal patient discomfort.
