Zirconium is as durable as the enamel of natural teeth and therefore, Zirconium crowns except in cases of injury, it is unlikely to break in general
Zirconium is a new generation of material for dental structures, which is hard as a metal and its durability has long been proven, as it is used in armor-piercing clothing in the army. Zirconium is biocompatible and does not cause allergies.
Clinical trials and testing of the materials have shown that the use of zirconium oxide (ZnO2) guarantees safe, long-lasting and stable dental restoration and to date no negative effects or allergies caused by zirconium have been identified and this material has been used for over 10 years, successfully by the dental industry.
What are the advantages of zirconium constructions?
The advantage of all-zirconia constructions is the thinner walls compared to metal ceramics. Preparing a tooth for a cermet crown requires taking 1.5 to 2.0 mm of hard tooth tissue. While in the case of the zirconium crown, only 0.3 to 0.5 mm is removed from the tooth surface. That is why the crown or bridge becomes finer, not as massive as cermets. This in turn leads to sparing of the gums.
Zirconia is as durable as the enamel of natural teeth and therefore, except in cases of injury, it is unlikely to break in everyday circumstances.
Due to its ability to transmit light, zirconium porcelain gives the crowns a natural look, which is in harmony with natural teeth and thus achieves an excellent aesthetic result. Due to the fact that there is no metallic reflection under the porcelain, the teeth do not look artificial.
Zirconia crowns do not show the discoloration of the gums, which is common in crowns with a metal skeleton. Cleaning is quick and easy. It has exceptional hardness and high density - withstands the highest chewing loads in all areas.
Due to the strength and durability of this type of porcelain, as well as its good aesthetic appearance, there are no restrictions on its use, the only contraindication for prosthetics with zirconium crowns is in patients with bruxism, but there is a solution for them, the structures are cut completely anatomical and after cementation a protective rail is made.
Zirconia porcelain can be used for the restoration of single dental crowns in the front and back of the jaws, in the manufacture of bridge structures in the absence of front or canines and also in prosthetics on implants.
