Dental ceramics are known for their aesthetic appeal, but they come with some significant drawbacks.
4 Key Points to Consider
1. Brittleness
Dental ceramics are made from inorganic, non-metallic materials, usually silicate-based.
These materials are heated at very high temperatures to form the final product.
This process makes the material strong under compression but weak under tension.
As a result, dental ceramics are more prone to cracking or breaking when subjected to forces like chewing.
2. Lower Durability
Compared to alternatives like porcelain-fused-to-metal crowns, all-ceramic crowns are not as durable.
This means they may need to be replaced or repaired more frequently.
The durability issue is especially noticeable in areas of the mouth that experience high functional forces, such as the molars.
3. Impact on Adjacent Teeth
Ceramic crowns can weaken the permanent tooth next to them more than metal or resin crowns.
This is because ceramics, while providing excellent aesthetics, do not offer the same level of protection or support to neighboring teeth as other materials might.
4. Need for Hardening
Before use, dental ceramics must be hardened through processes like firing or sintering in dental furnaces.
These processes require precise control of high temperatures and pressures.
This adds complexity to the fabrication process and can potentially increase costs.
