The article discusses common errors in full-crown tooth preparations. Some of frequently encountered errors are inadequate tooth reduction on incisal or occlusal surfaces, inadequate tooth reduction on the preparation's axial walls, overreduction of tooth structure, excess taper on the tooth preparation...
The tooth must be adequately prepared for this restoration to be successful, and substantial tooth reduction is often required. The crown must be sufficiently thick to hide the metal substructure and the opacious porcelain used to mask this alloy. When preparing a tooth, a systematic and organize...
