Dental ceramics are inorganic, non-metallic materials, typically silicate-based, that are heated at high temperatures to create various dental applications such as resin-composite restorative materials, cementation agents, and fixed prostheses.
These materials are crucial in dentistry for their aesthetic properties and functionality in repairing and rebuilding teeth.
1. Resin Composites
Resin composites are used extensively in dental restorations due to their superior aesthetic properties.
They consist of a resin binder, typically an aromatic dimethacrylate monomer, and a ceramic filler which is often pulverized quartz, colloidal silica, or silicate glasses containing strontium or barium to enhance X-ray opacity.
Despite their aesthetic appeal, resin composites have limitations such as shorter longevity compared to dental amalgams, particularly in posterior restorations.
They are also prone to degradation due to the breakdown of the bond between filler particles and the matrix, and can be compromised by fatigue and thermal cycling, potentially leading to the formation of caries or cavities.
2. Dental Porcelain
Dental porcelain is a type of unglazed ceramic used primarily for making crowns and veneers.
It is composed of approximately 60% pure kaolin (a type of clay) and about 40% other additives like feldspar, quartz, or oxides to enhance durability and color.
Porcelain is valued for its strength and versatility, but it is softer than natural dentin and requires support from the natural tooth structure or a bonding agent to maintain its integrity.
3. Mechanical Properties and Sintering
The development of new dental ceramics involves rigorous testing of their physical properties, such as sintering behavior and mechanical strength, to ensure they match or exceed those of existing materials.
For instance, the sintering of zirconia blocks is analyzed for their linear shrinkage and mechanical properties to evaluate their suitability for clinical use.
4. Dental Furnaces and Ceramic Processing
Dental furnaces are used to process ceramic materials into restorations such as crowns, bridges, inlays, and onlays.
These furnaces are essential for the high-temperature treatments necessary to harden and shape the ceramics.
5. Metal-Ceramic Systems
Metal-ceramic systems are designed to combine the aesthetic qualities of ceramics with the mechanical strength of metals, addressing the inherent brittleness of ceramics.
This combination is crucial for dental prostheses that need to withstand the functional forces of the oral cavity, such as during chewing.
