Composite resin interim restorations for broken-down nonvital posterior teeth.
The fabrication of interim restorations using a retentive groove preparation design with a custom composite resin core material has been used in my private practice for more than ten years with gratifying results. In the past 2 1/2 years, more than 800 such restorations have been documented and placed at the University of Southern California School of Dentistry. Pre-endodontic preparation of nonvital teeth with advanced carious lesions and defective restorations eliminates potential impediments to pulp therapy. A quality interim restoration provides the dentist with a diagnosis of restorability before pulp therapy, protects severely damaged teeth, and promotes periodontal health. Future endodontic treatment is simplified and patient satisfaction is increased.
