This has challenged the prosthodontic fraternity to come up with new and innovative designs to restore the posterior natural endodontically treated teeth. Degree of difficulty in treating posterior teeth with post core is their root configuration and relation that is never parallel especially in maxillary molars. With palatal root being the widest of all roots, the mechanical advantage that it offers cannot be overlooked and therefore involvement of palatal root for any post core system is mandatory. This article describes a technique of fabricating a cast post core for multiple divergent maxillary root canals using the principle of sliding one component over the other. Keywords- cast core, dowel crown, endodontics, metal ceramic, crown and bridge INTRODUCTION Among the various post core systems, the cast core is versatile because it allows one to overcome any obstacle without compromising the principles of fixed partial denture prosthesis designing. The mechanical advantage that a cast post offers strengthens the weakened tooth but can do reverse if www.jmscr.igmpublication.org Impact Factor 3.79 ISSN (e)-2347-176x
