title: Evaluation and restoration of endodontically treated posterior teeth.
abstract: The increasing acceptance and utilization of endodontic therapy for the preservation of broken-down posterior teeth presents the practitioner with many difficult restoration problems. If 25% or more of the coronal tooth structure is lost, some form of artificial dentin augmentation is required to provide adequate support and retention for the final restoration. Criteria to be used in the prerestorative evaluation of endodontically treated teeth are presented. Various methods and techniques to protect the remaining toth structure from fracture and to provide support and retention for the final restoration are described.
