| Nupur Rathi, Rashmi Malhotra, Vishwadeepak Singh | |
Gross destruction of permanent natural molars results in complex restorations. Among them are the cast post core crowns, especially when a tooth has divergent roots and two posts with different angulations need to be placed inside the post space. We present restoration of mandibular left second molar with a key and a keyway system of cast posts and a core. The fabrication was done indirectly on a working cast and the two individual components of the core were cemented together over which a metal ceramic crown was placed. Keywords: caries, endodontic, post space, elastomers. |
