Post Endodontic Reconstruction

Restoration of the endodontically treated teeth is complicated by the fact that, some or all of the coronal tooth structure which normally would be used in the retention of a restoration has been destroyed by caries, previous restorations, trauma or the endodontic access preparation itself. Already structurally weakened, such teeth are often further weakened by the endodontic procedures designed to provide optimal access and by the restorative procedures necessary to rebuild the tooth. Loss of inherent dentinal fluid may also effect an alteration in tooth properties. It is therefore accepted that endodontically treated teeth are weaker and tend to have a lower lifetime prognosis. They require special considerations for the final restoration, particularly where there has been extensive loss of tooth structure.
