Where the zirconium crowns are indicated?
Zirconium crowns and bridges are so strong they can be used anywhere in the mouth. Zirconium crowns can withstand the biting pressure of the front teeth as well as back teeth grinding.
The look of zirconium 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 usable within dental work. Zirconium crowns can be fixed using traditional dental cements.

Zirconium crowns have quickly become the preferred material for dental crowns. Zirconium is a very strong substance that can endure wear and tear of everyday use. When looking at Zirconium 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.
Zirconium vs Porcelain
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. Zirconium 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.
