Zirconia-based materials are widely used in various applications, particularly in dental restorations. However, like any material, they come with their own set of drawbacks. Understanding these drawbacks is crucial for making informed decisions about their use.
5 Key Points to Consider About Zirconia-Based Materials
1. Friction and Wear on Opposing Teeth
One of the most significant concerns with zirconia-based materials is the potential friction against the tooth root and the wearing down of opposing teeth. Regular check-ups can help minimize this risk.
2. Transformation of Zirconia Under Stress
Zirconia can transform from tetragonal to monoclinic under external stresses such as sandblasting, grinding, and thermal aging. This transformation is accompanied by a volume expansion that induces compressive stresses, which can prevent the propagation of cracks.
3. Higher Cost Compared to Metal-Ceramic Crowns
Zirconia crowns tend to be more expensive than metal-ceramic crowns. However, they offer advantages such as being stronger and lighter. Zirconia is also compatible with humans and does not cause allergic reactions.
4. Challenges for Ceramists
Zirconia-supported restorations present challenges for ceramists due to the material's insulating properties during the firing and cooling processes. A slow cooling protocol is recommended to ensure tension-free cooling.
5. Overall Drawbacks Versus Advantages
While the drawbacks of zirconia-based materials primarily revolve around concerns about friction and wear, the potential transformation of the material, and the challenges faced during the fabrication process, these drawbacks are minimal compared to the many advantages offered by zirconia.
