Dental ceramics definition.

Dental ceramics possesses very good resistance to the compressive stresses however they are very poor under tensile and shear stresses. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Congenital deformity resulting in lack of fusion of the soft and or hard palate either partial or complete. Dental ceramics synonyms dental ceramics pronunciation dental ceramics translation english dictionary definition of dental ceramics.

Engineering assessments of clinical function are dealt with and literature is reviewed on the clinical behaviour of all ceramic systems. Dental ceramics are mainly composed with crystalline minerals and glass matrix. Dental ceramics exhibit excellent biocompatibility with the oral soft tissues and are also chemically inert in oral cavity. Dental ceramics are presented within a simplifying framework allowing for facile understanding of their development composition and indications.

Practical aspects are presented regarding the choice and use. For certain dental prostheses such as three unit molars porcelain. Crystalline minerals include feldspar quartz and alumina and perhaps kaolin as glass matrix 1 10 11. Introduction ceramic is defined as product made from non metallic material by firing at a high temperature.

Ceramics is a material that is opaque and porous thus relatively weak. This imparts brittle nature to the ceramics and tend to fracture under tensile.

Dental porcelain mainly differs from traditional ceramics in terms of firing techniques which make it more suitable for dental restoration.

Dental porcelain has very stable chemical properties and outstanding esthetics which are unlikely to be influenced by time. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. The detailed composition of dental ceramics was discussed in table 2.
