Zirconia
The look of Zirconia crowns and bridges is so close to natural teeth that it is hard to tell the difference and it is this quality which makes it very useable within dental work. Zirconia crowns can be fixed using traditional dental cements.
Zirconia crowns have quickly become the preferred material for dental crowns. Zirconia is a very strong substance that can endure wear and tear of everyday use. When looking at Zirconia crowns from an aesthetic point it is clear and very similar to a natural tooth and reflects light the same way. This may be important if your new crowns are on the front of your mouth and it is particularly relevant in cases where the crown will be seen next to the natural teeth.
Porcelain is the conventional material used for the new crowns however, Full porcelain can chip or break. This is overcome by making the crowns from the metal, in this case metal Zirconia, then merge the porcelain on the outside. Zirconia metal gives the strength while the porcelain gives the appearance of a normal tooth. Zirconia crowns allow light to pass as a normal tooth would and that gives a natural look, unlike other metal cores that are block the light.
Full Form Zirconia
Monolithic Zirconia crowns and bridges are milled from solid blocks of zirconia, sintered at over 1500°C and nearly unbreakable. In its pre-sintered form, the zirconia is stained in a range of colours to achieve a base colour, which helps to improve the aesthetics of the final restoration.
Designed using state-of-the-art CAD/CAM technology, Monolithic Zirconia crowns are Precision’s recommended choice for posterior restorations and represent a great alternative to posterior porcelain-fused-to-metal, laminated zirconia or gold crowns.
Key characteristics:
- Full-contoured zirconia
- Biocompatible
- Versatile material
- Stained prior to sintering for base colour
- CAD/CAM manufactured – for accuracy of fit
- Monolithic form – no risk of delamination
- Very strong restoration
Overview
Zirconia crowns won’t corrode and the normal black gum line that you can see around a porcelain fused metal crown, won’t happen because of the strong ceramic material used. Also the normal too hot/cold sensations you can feel with other crowns does not normally occur because of the lack of electrical conductivity.
