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.
Components of dental ceramic.
Feldspathic ceramics are the oldest of the dental ceramics and are very esthetic but relatively weak.
Ceramic used in dental application differs in composition from conventional ceramic to achieve optimum aesthetic components such as translucency.
Lithium disilicate crystals are created by adding li 2 o lithium oxide to the alumino silicate glass.
As example the composition of dental feldspathic porcelain is as follows.
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.

Types and uses of ceramics in dentistry today.
Feldspathic ceramics are still common in dental restorations today.
Feldspathic ceramics porcelains are glassy ceramics that form from the combination of feldspar silica and alumina.
