Dental ceramics are made from materials that contain mainly silicon dioxide (silica or quartz) along with various amounts of alumina. These materials are manufactured using a process called heat pressing, which is performed in an investment mold.
There are different types of dental ceramics, including leucite-reinforced feldspar glass ceramics and porcelain. Porcelain, for example, is composed of about 60% pure kaolin (a type of clay) and about 40% other additives such as feldspar (to give it color), quartz (to increase hardness), or oxides (such as tuff or rhyolite) to enhance durability.
The manufacturing process of dental porcelain involves mixing clay and mineral powders together and firing them at high temperatures. This process creates strong and beautiful ceramics. Thin sheets of ceramic can be cut into various shapes and then fired at high temperatures, resulting in beautiful colors and patterns. These are known as glazed ceramics. There are also thicker, unglazed ceramics that take longer to bake in the furnace but do not burn away like regular glass.
Dental ceramics are used in the production of dental prostheses such as crowns, bridges, inlays, and onlays. They replace missing or damaged dental structures. Ceramics used in dentistry are inorganic and non-metallic materials, usually of a silicate nature. They are produced by heating raw minerals at high temperatures. Ceramics are usually brittle, meaning they have high compressive strength but low tensile strength and may fracture under low strain levels.
