Dental ceramics are primarily composed of inorganic, non-metallic materials, often of a silicate nature.
These materials are heated at high temperatures to form various dental restorations.
5 Key Materials You Need to Know
1. Resin Composites
Resin composites are used for repairing and rebuilding teeth.
They consist of a resin binder, typically an aromatic dimethacrylate monomer, and a ceramic filler.
The filler is usually pulverized quartz, colloidal silica, or silicate glasses containing strontium or barium to enhance X-ray opacity.
Despite their aesthetic appeal, resin composites may lack the longevity of dental amalgams and can degrade over time due to breakdown of the bond between filler particles and the matrix.
2. Dental Porcelain
Dental porcelain is a crucial material in dental ceramics.
It is composed of about 60% pure kaolin (a type of clay) and about 40% other additives such as feldspar for color, quartz for hardness, and various oxides to enhance durability.
Porcelain is versatile and can be shaped and fired at high temperatures to create various dental restorations like crowns, bridges, inlays, and onlays.
3. Metal Ceramic Systems
Metal ceramic systems combine the aesthetic properties of ceramics with the mechanical strength of metals.
They are essential for creating durable and visually appealing dental prostheses.
4. Technical Ceramics
Technical ceramics are used in advanced applications.
These ceramics are processed under precise conditions in dental furnaces.
Modern dental furnaces are microprocessor-controlled, allowing for precise temperature regulation and programmability, which is crucial for the uniform heating and sintering of ceramic materials.
5. Dental Furnaces
These materials are processed using dental furnaces.
The furnaces operate at high temperatures and pressures.
Their precise control ensures that the dental ceramics do not shrink or distort during the firing process.
This precision is vital for maintaining the integrity and fit of the dental restorations.
