The Complete Cast Crown Preparation

Although esthetic factors may limit its application, the all-metal complete cast crown should always be offered to patients requiring restoration for badly damaged posterior teeth. The complete cast crown has the best longevity of all fixed restorations. It can be used to rebuild a single tooth or as a retainer for a fixed partial denture (FPD). It involves all axial walls as well as the occlusal surface of the tooth being restored (Fig. 8-1).

Preparation for a complete cast crown requires that adequate tooth structure be removed to allow restoration of the tooth to its original contours. Tooth structure should be preserved when possible, but reduction should produce a crown of acceptable strength.
