Composition Of Dental Ceramics

For certain dental prostheses such as three unit molars porcelain.

Composition of dental ceramics.

Dental ceramics can be classified in a number of different ways including by their composition processing method fusing temperature microstructure translucency fracture resistance and abrasiveness. The most common ceramics used in dentistry are alloys of 3 main metallic oxides sio2 al2o3 k2o. Many dental ceramics contain a crystal phase and a silicate glass matrix phase. Divided into two parts such as part i and ii.

Part i reviews the composition structure and properties of dental ceramics from the literature available in pubmed and other sources from the past 50 years. Divided into two parts such as part i and ii. The detailed composition of dental ceramics was discussed in table 2. This article is a review of dental ceramics.

Crystalline minerals include feldspar quartz and alumina and perhaps kaolin as glass matrix 1 10 11. Esthetically these materials are preferred alternatives to the traditional materials in order to meet the patients 39. 1 for the purposes of this article the term ceramic is used to include all metal free restorations generally all ceramic restorations have been confined to the anterior region until. Dental porcelain also known as dental ceramic is a dental material used by dental technicians to create biocompatible lifelike dental restorations such as crowns bridges and veneers evidence suggests they are an effective material as they are biocompatible aesthetic insoluble and have a hardness of 7 on the mohs scale.

Ceramics or porcelains are chemically intimate mixtures of metallic and non metallic elements that allow ionic k2o and or covalent bonding sio2 to occur. Principal crystal phase or matrix phase processing method casting sintering partial sintering glass infiltration slip casting and sintering. Dental ceramics are mainly composed with crystalline minerals and glass matrix. Anusavice uses or indications anterior and posterior crown veneer post and core fixed dental prosthesis ceramic stain glaze composition.

Composition of dental ceramics and dental porcelain. This article is a review of dental ceramics. Dental ceramics are nonmetallic inorganic structures primarily containing compounds of oxygen with one or more metallic or semi metallic elements aluminum boron calcium cerium lithium magnesium phosphorus potassium silicon sodium titanium and zirconium. Several modifications have been made in ceramics in order to address this quandary.
