Zirconia in Dentistry
Zirconia is one of the most widely used high-performance dental materials in the field of dentistry due to its significant aesthetic advantages and mechanical properties.
One of the main advantages of zirconia is that it allows for the fabrication of dental restoration components that pose no risk of allergic reaction when in contact with human soft tissues. In addition, zirconia implants offer greater stability against mechanical stress.
As a high-strength crystalline ceramic with a translucent finish that can achieve shades very similar to those of natural teeth, zirconia has become the ideal material for dental applications.
Advantages and Applications of Zirconia
High-strength ceramics, particularly zirconia, are indicated when a dentist must treat a patient with significant loss of tooth structure, where there is a risk of flexure and tension, and where bonding and sealing cannot be maintained. The most typical case involves full posterior crowns with subgingival margins.
Although its use has become widespread, the vast potential of zirconia has made it the subject of research in the fields of dental prosthetics and medical instruments. Looking ahead, new applications will undoubtedly be found for this material, which is also cost-effective.
Experts’ recommendations for achieving the best aesthetic results with maximum functionality when using zirconia are:
- Use a 0.5 mm to 1 mm porcelain core to ensure a good finish.
- Create a full-contour restoration for high-risk molar cases.
- In the molar region, a full-contour zirconia restoration should only be used when there is no other clinical option.
- When the risk of losing the bond or seal is high, zirconia is the ideal metal-free ceramic.
While the most conservative restoration that meets clinical criteria should always be chosen, zirconia stands out as the aesthetic alternative with characteristics and translucency most similar to those of natural teeth.
