Dental Ceramic Technique

For certain dental prostheses such as three unit molars porcelain.

Dental ceramic technique.

Dental porcelain mainly differs from traditional ceramics in terms of firing techniques which make it more suitable for dental restoration. A dental substructure is a framework covered with porcelain that forms the. Ceramics is a material that is opaque and porous thus relatively weak. Dental porcelain has very stable chemical properties and outstanding esthetics which are unlikely to be influenced by time.

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. Heraceram is a flexible veneer system for all indications and aesthetic requirements. Introduction ceramic is defined as product made from non metallic material by firing at a high temperature. The dental ceramic techniques certificate is comprised of four courses that focus on the physical properties of metals and ceramic and the fabrication of metal ceramic and all ceramic crowns and bridges.

Dental porcelain has been used as artificial porcelain teeth in complete or partial denture porcelain crown or inlay and dental cement. The amount of abutment prepared should be greater than that in a full porcelain crown. Esthetically these materials are preferred alternatives to the traditional materials in order to meet the patients demands for improved esthetics. Dental ceramics are usually composed of nonmetallic inorganic structures primarily containing compounds of oxygen with one or.

For classical dental porcelain quartz kaolin and feldspar were the raw materials used for preparing the porcelain. Ceramics have also been used to restore carious enamel and dentin or missing teeth. In dental ceramic sub structures sintered refractory materials have little or no glass between the refractory particles dental ceramic substructuresare made of aluminaor zirconia fused at very high temperatures and need no glass to make them hard. Shade with depth in a metal ceramics system can be obtained only with a sufficient thickness of translucent porcelain.

The background for basic techniques for building porcelain layers is explained with photographs in this chapter.
