Crowns based on zirconium oxide are excellent aesthetics, strength, reliability, health and natural color of the gums!
When are zirconium crowns used:
- single crowns
- bridges
- veneers
- prosthetics on implants
Why the crown on basis of zirconium oxide is better than metal-ceramic crowns?
The high aesthetics, strength and biocompatibility of zirconium oxide makes it an ideal material for prosthetics of front and chewing teeth. This is the latest technology for making artificial Zirconia crowns, which came to us from Europe.
Crowns on zirconium oxide are not inferior in strength to metal-ceramic crowns, and their aesthetic capabilities are many times superior to metal-ceramic.
The fact is that the very compound of zirconium oxide has a white color — this is the optimal imitation of the shade of natural teeth, in contrast to the metal color of the frame of the metal-ceramic crown. In order to exclude the transmission of metal through a layer of ceramics, in the manufacture of metal-ceramic crowns used opaque (opaque) ceramic mass, so the metal-ceramic crowns have no depth of color and they do not pass light through the metal. As a result, there is no illumination of the gum from the inside, as in the area of a natural tooth, so the gum in the area of the metal-ceramic crown looks darker.
The frame of zirconium oxide is milled under the control of a computer, so this crown “sits” on the tooth much more accurately than the metal-ceramic frame, which is obtained by casting, resulting in shrinkage of the metal. If there are gaps between the crown and the tooth, microbes will accumulate in them, which leads to inflammation of the gums, so there is often a red inflamed gum around the metal-ceramic crowns. The gums around the crowns on zirconium oxide always have a healthy appearance. Crowns based on zirconium oxide are made much thinner than metal-ceramic, so under the crown based on zirconium oxide is not required to depulpate (remove the nerve) tooth. The tooth remains alive and serves under the crown much longer than a depulpated tooth under a metal-ceramic crown.
Why do we recommend zirconium crowns?
The tooth remains alive and is much longer than the pulpless tooth for metal ceramic crown.
