Root extrusion, a practical solution in complicated crown-root incisor fractures.

Implants and fixed and removable prostheses are very successful in replacing missing units but their cost can be inhibitory to a number of patients. In addition fixed and removable prostheses can be destructive to sound abutment teeth and can result in damage to dental and soft tissue. This report describes the restoration of a tooth with a complicated incisor crown-root fracture that extended below both the gingival cuff and the alveolar crest, by using remaining tooth tissue. The restoration was completed after root extrusion with a cast post, diaphragm and core, and porcelain crown.
