Fundamentals of Tooth Preparations for Cast Metal and Porcelain Restorations

From Dentistry Made Simple Dentistry Made Simple

A comprehensive manual on fixed prosthodontics, focusing primarily on the intricate process of tooth preparation for various cast metal and ceramic restorations. It emphasizes the critical importance of precise tooth preparation to ensure the longevity, retention, and structural durability of restorations, using detailed anatomical measurements and biomechanical principles. The sources systematically explain different crown and inlay designs, such as full veneer crowns, partial veneer crowns (like three-quarter and seven-eighths crowns), inlays, and onlays, detailing the specific instrumentation, techniques, and finish line configurations required for each. Furthermore, the text addresses modifications for damaged teeth, the need to maintain gingival health by controlling margin placement, and the biomechanics of retention and resistance, including the effects of taper, surface area, and cement stress on restoration stability.
