The more restrictive term porcelain refers to a specific compositional range of ceramic materials made by mixing kaolin, quartz, and feldspar, and firing at high temperature. Ceramic is a popular material for making a crown because it can be made in tooth colour. Inlays and onlays can be made of gold, composite, or ceramic materials: Gold. 33 This is explained by radiant exposure (J/cm 2); that is, the product of irradiance (mW/cm 2) and light-curing time (s), 34 which indicates that an increase in light-curing time could be used to compensate for a reduction in irradiance. Due to their excellent biocompatibility, ceramic materials are recommended as the material of choice, from dental restorations and implants to bone grafting material. Ceramics composed of single element are rare. Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth. Other materials, like high glass ceramics (IPS Empress, VITA Mark II) are even more translucent and aesthetic, but are also much more fragile, even when compared to silicate ceramics. 34-37 The present results .

Ceramic is a popular material for making a crown because it can be made in tooth colour. Ceramics can be used on their own to create a restoration for a tooth either as an inlay, onlay, full crown or veneer or as a hybrid type crown (metal inner layer with porcelain/ceramic exterior). The inorganic component primarily consists of hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2, HA). Ceramics are used in restorative dentistry as full- and partial-coverage crowns, denture teeth, and as particulate fillers for resin matrix composite filling materials. Ceramics are widely used in dentistry due to its dual role strength and esthetics. Ceramics are used for manufacturing artificial teeth, pontics, facing, crowns and fixed bridges. Authors; Authors and affiliations; J. Li; G. W. Hastings; Chapter. Ceramic materials can be identified by their general properties like high hardness, brittleness, chemical stability and low thermal conductivity. Since gold is extremely durable, it protects weakened teeth cusps caused by cavities and trauma.
