One of the greatest frustrations for cosmetic dentists is the inability to use zirconia for the fabrication of anterior prostheses due to the inherent opaque nature of the material. What if somehow translucent zirconia crowns could be prepared that possessed the same translucency and dentine, combined with the conventional strength and durability of zirconia? Yes, it certainly possible! Thanks to the latest zirconia brands, Bruxzir and Crystal are now producing a zirconia material specifically designed for anterior prostheses!
Why Conventional Zirconia Could not be Used for Anterior Teeth?
Zirconia is inherently an opaque material, starting as a white powder. Therefore, initially it was only used as a coping material for the fabrication of all-ceramic restorations. The high opacity of zirconia ceramics is due to their highly crystalline structure in which the constituent atoms are highly organized and packed closely. One of the major requirements for an anterior zirconia is that it should have translucency comparable to that of the dentine. Therefore, while translucency improved over the years enough to create full contour posterior restorations, conventional zirconia was generally not used for making anterior crowns and bridges.
Anterior Zirconia Crowns and Bridges
You must be wondering as to why zirconia is the best material for making anterior crowns and bridges? The answer is the excellent biocompatibility, durability and strength of the zirconia ceramics. The only drawbacks of using zirconia on anterior teeth was its opacity. However, most manufacturers are now offering zirconia ceramics that are highly translucent and esthetic. For example, the Bruxzir anterior and the crystal brands are ideal for the fabrication of anterior.
What are the Advantages of Anterior Zirconia Crowns and Bridges?
Thinking why you should spend more money on anterior zirconia crowns, veneers and bridges? Here’s why:
- Esthetics – the newer zirconia ceramics (Bruxzir anterior, crystal anterior) are highly translucent. Therefore, they possess excellent esthetics and are ideal for use in restoration of anterior teeth.
- Biocompatibility – zirconia ceramics are highly biocompatible. This means that they will not elicit any harmful response within the body, when they placed inside the oral cavity.
- Durability – anterior zirconia crowns are very hard and possess excellent strength. Therefore, they can be expected to provide services throughout the lifetime. Unlike the other ceramics crowns which usually need to be replaced after every 5 years, zirconia ceramics will never give up on you!
- Minimal Requirement for Tooth Reduction – owing to their excellent strength, Bruxzir anterior and crystal zirconia ceramics require lesser tooth reduction than the other ceramic materials.
