Dental Ceramics Definition

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.

Dental ceramics definition.

Practical aspects are presented regarding the choice and use. This imparts brittle nature to the ceramics and tend to fracture under tensile. Ceramics is a material that is opaque and porous thus relatively weak. For certain dental prostheses such as three unit molars porcelain.

Dental ceramics possesses very good resistance to the compressive stresses however they are very poor under tensile and shear stresses. Dental ceramics are mainly composed with crystalline minerals and glass matrix. Engineering assessments of clinical function are dealt with and literature is reviewed on the clinical behaviour of all ceramic systems. See metals classification of.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.

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. See definition under direct.

Dental porcelain has very stable chemical properties and outstanding esthetics which are unlikely to be influenced by time. Dental porcelain mainly differs from traditional ceramics in terms of firing techniques which make it more suitable for dental restoration. Introduction ceramic is defined as product made from non metallic material by firing at a high temperature. Congenital deformity resulting in lack of fusion of the soft and or hard palate either partial or complete.

A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Dental ceramics exhibit excellent biocompatibility with the oral soft tissues and are also chemically inert in oral cavity. The detailed composition of dental ceramics was discussed in table 2.
