Dental treatment:Zirconia

we present a graphic with example of porcelain crowns

As before, the outer layer, so the one visible in the face is porcelain, the skeleton of such a crown, however, is made of zirconium.

Zirconium has the advantage over metal that it is white and perfectly transmits light, so the above-mentioned problems that can occur with crowns on metal, do not exist here.

It should be remembered at the same time that zirconium, although it is white, belongs to the group of transition metals, so it is still a metal! We mention this because many people mistakenly think that because zirconium is white to metal it does not count. Thus, porcelain crowns on zirconium have a very high aesthetics, and thanks to the high light transmittance they imitate natural teeth perfectly. Perfect for rebuilding the front teeth (canines and incisors). Zirconium, however, is not as durable as metal, so it is not recommended to rebuild lateral teeth (molars and premolars), because it will not withstand the loads they are subjected to during chewing.

The price of a porcelain crown on zirconium is higher than that on metal primarily due to the time it takes for it to be made (it is almost twice as long as the need for a crown on metal).

All-porcelain - metal free (all-ceramic)

These are entirely porcelain crowns, both their base and the outer part. They are also called metal free crowns, due to the lack of metal in their composition. As for their aesthetic qualities, just like crowns on zirconium, they imitate real teeth very well, because their foundation is white like zirconium. However, they are used in most cases for the reconstruction of the front teeth (from three to three most often), because they are not strong enough to ‘accept’ the load that rests on the side teeth during chewing.

In most cases porcelain crowns can serve patients for very long years. However, sometimes, under unfavorable conditions, unfortunately their "viability" can be significantly reduced. The worst factors affecting the condition of crowns and bridges are: bruxism, incorrect occlusion and inadequate oral hygiene.

About what kind of crowns will be suitable for a particular patient decides primarily the doctor and the patient of course, when visiting a dental office, because everything really depends on the patient's oral cavity situation and on its financial capabilities.
