Zirconia blocks are widely used in oral restoration, mainly due to their excellent physical properties, biocompatibility and aesthetic effects. The following is a detailed explanation of the application of zirconia blocks in oral restoration:
1. Zirconia porcelain restoration
Crowns and Bridges: Zirconia is widely used in the manufacture of all-porcelain crowns and Bridges due to its high strength and toughness. These restorations are not only able to withstand chewing forces in the mouth, but also have good aesthetics and can simulate the appearance of natural teeth.
Aesthetic restoration: For aesthetic restoration of front teeth, zirconia porcelain crowns provide a more natural and realistic effect, avoiding the gray line problems that can be caused by traditional metal materials.
2. Zirconia implant and abutment
Implants: Although titanium implants currently dominate the field of oral implants, zirconia implants are gradually gaining attention due to their good biocompatibility and aesthetic effects. Zirconia implants are able to reduce the risk of surrounding tissue lesions and may reduce the incidence of peri-implant disease.
Abutment: Zirconia abutment is used to replace traditional titanium abutment because of its excellent mechanical properties and aesthetics. The zirconia abutment can not only improve the stability of the surrounding soft tissue, but also reduce the color difference of the gum and improve the overall aesthetics of the restoration.
3. Zirconia post core
Fixed restoration: Zirconia post core is widely used in fixed restoration of teeth because of its high strength and good biocompatibility. Compared to traditional metal post cores, zirconia post cores provide better aesthetic results and reduce the risk of MRI image distortion.
Enhance the strength of the restoration: Zirconia post core can provide additional support for the restoration and enhance its fracture resistance, thus extending the service life of the restoration.
4. Advantages of zirconia in oral repair
Biocompatibility: Zirconia has good biocompatibility, does not cause allergic reactions or rejection, and is conducive to the health of oral tissues.
Durability: Zirconia's high strength and wear resistance make it able to withstand long-term chewing forces without damage, improving the durability of the restoration.
Aesthetic effect: The color and transparency of zirconia can be adjusted, which can simulate the appearance of natural teeth and provide a natural and beautiful restoration effect.
Machining accuracy: Through CAD/CAM technology, zirconia blocks can be precisely machined to produce highly personalized restorations to meet the different needs of patients.
5. Precautions
Although zirconia block has many advantages in oral repair, it is still necessary to pay attention to its brittleness during use to avoid excessive force resulting in rupture.
When selecting zirconia prosthetics, individual design should be carried out according to the specific situation and needs of patients to ensure the optimal repair effect.
In summary, zirconia blocks have broad application prospects in oral restoration. With the continuous progress of science and technology and the improvement of people's requirements for oral health and aesthetics, its application will be more and more extensive.
