Components Of Dental Ceramic

Ceramic used in dental application differs in composition from conventional ceramic to achieve optimum aesthetic components such as translucency.
Components of dental ceramic. Dental ceramics are usually referred to as nonmetallic inorganic structures primarily containing compounds of oxygen with one or more metallic or semi metallic elements like aluminum calcium lithium magnesium phosphorus potassium silicon sodium zirconium titanium 1 10. Types and uses of ceramics in dentistry today. Lithium disilicate crystals are created by adding li 2 o lithium oxide to the alumino silicate glass. The most common ceramics used in dentistry are alloys of 3 main metallic oxides sio2 al2o3 k2o.
Feldspathic ceramics porcelains are glassy ceramics that form from the combination of feldspar silica and alumina. Ceramics or porcelains are chemically intimate mixtures of metallic and non metallic elements that allow ionic k2o and or covalent bonding sio2 to occur. The term dental ceramics comprises a wide variety of materials that reaches from filled glasses to nearly dense sintered ceramics from products that are shaped from powders and melts to components milled from blanks before or after sintering. It also acts as a flux lowering the melting temperature of the material.
