Key developments include McLean and Hughes' aluminous core porcelain in 1965, In-Ceram in the 1980s using slip casting, and machinable ceramics in the 1990s using CAD/CAM. The document also examines methods to strengthen porcelain, all-ceramic systems like In-Ceram, castable ceramics including Di-Cor and Cerestore, and machinable ceramics. It provides details on the composition, fabrication process, properties and clinical performance of various ceramic materials.
The document discusses artificial teeth materials, including acrylic and porcelain teeth. Acrylic teeth are easier to adjust and bond chemically to the denture base, making dentures lighter. However, they stain easily and wear down over time. Porcelain teeth are harder, resist staining and wear, but are more brittle, expensive, and do not bond chemically to the denture base. The document compares the properties, advantages, and disadvantages of acrylic and porcelain teeth in detail.

This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.
