Components Of Dental Ceramic

It also acts as a flux lowering the melting temperature of the material.

Components of dental ceramic.

Leucite is created in dental porcelain by increasing the k 2 o potassium oxide content of the alumino silicate glass. Types and uses of ceramics in dentistry today. As example the composition of dental feldspathic porcelain is as follows. Feldspathic ceramics are still common in dental restorations today.

Kaolin 3 5 quartz silica 12 25. The most common ceramics used in dentistry are alloys of 3 main metallic oxides sio2 al2o3 k2o. 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. Composition of dental ceramics and dental porcelain.

Ceramic used in dental application differs in composition from conventional ceramic to achieve optimum aesthetic components such as translucency. 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. Ceramics or porcelains are chemically intimate mixtures of metallic and non metallic elements that allow ionic k2o and or covalent bonding sio2 to occur.
