Restoration of badly broken, endodontically treated posterior teeth

Abstract

It is generally agreed that the successful treatment of a badly broken tooth with pulpal disease depends not only on good endodontic therapy, but also on good prosthetic reconstruction of the tooth after the endodontic therapy is complete. Often, we come across an endodontically treated tooth with little or no clinical crown in routine clinical cases. In such cases, additional retention and support of the restoration are difficult to achieve. Two case reports are discussed here where structurally compromised, endodontically treated, posterior teeth were restored using the Richmond crown in the first case, and by the use of two nonparallel cast posts in the second case.

Keywords: Cast post; Richmond crown; post endodontic restorations.
