Dental casting materials, whose main component is porcelain, designed to make a positive copy of a given area of the oral cavity using a mold previously taken at the dentist\'s office. These dental porcelains consist of biologically inert and esthetically pleasing materials that have considerable strength, whiteness, and a high resistance to chemical attack and thermal shock. The materials are usually poured into a mold which contains a hollow cavity of an appropriate shape to fit teeth and/or oral tissue, allowed to solidify and then ejected or broken out of the mold to complete the process. Porcelain casting materials are used mainly in dental laboratories to make bridges, crowns, and veneers.
