Ceramic Past, Present, and Future

Bol

Dental ceramics are vital in restorative dentistry due to their biocompatibility, chemical stability, and esthetic appeal. Composed of a glassy matrix with crystalline reinforcements like feldspar, leucite, lithium disilicate, and zirconia, their properties vary based on composition and structure. While feldspathic porcelains offer high translucency, their low strength necessitates reinforcement through materials like lithium disilicate and zirconia. Ceramics are classified by usage, composition, processing method, and mechanical and optical characteristics. Techniques such as CAD-CAM and hot pressing enhance accuracy and durability. Surface finishing and appropriate bonding protocols, including etching or air abrasion, improve performance and longevity. Despite their brittleness under certain stresses, ceramics show high compressive and fatigue strength, which can be improved through various strengthening methods. Achieving an ideal balance between esthetics and strength is crucial for clinical success.
