The zirconium oxide and lithium di-silicate is a highly resistant bio-compatible material, used in general medicine for hip prostheses. In dentistry, it is used to create ceramic zirconium dental crowns.
Absence of grey lines
Lack of gum irritation
The advantages of using zirconium as a support for ceramic dental crowns are:
It presents a trans-lucidity similar to the one of the teeth, so that the light reflected by the zirconium looks like a natural tooth, although the support is metallic
It has a higher durability with respect to the other materials used as a support
It does not produce grey lines on the gums, like the metal-ceramic crowns
The patient does not often feel a metallic taste
The zirconium dental crowns are much lighter than the metallic ones, thus the patient gets used to it more easily
It does not cause allergies
It does not cause gum (nerve) irritations
The precision of a zirconium work is guaranteed because the structure is performed by means of a computer (called cad/cam), by cutting a block of zirconium
