A Systematic Approach to Restore Grossly Decayed Multirooted Teeth: Split Cast Post and Core

Abstract

Endodontically treated molars with almost total coronal destruction may be salvageable by using multiple posts in divergent canals. The fabrication of dowel and core for multirooted teeth can be a vexing problem, especially when there is minimal coronal dentin. A number of methods have been suggested for making a cast dowel and core using two or more of the canals to increase retention of the prosthesis. This article presents a clinical report on fabrication of split cast post and core by a direct technique that is efficient and enables the dentist to use the maximum length available in each canal, despite the degree of divergence in multirooted teeth.
