Let us begin by defining zirconia.
Zirconia is a chemical element with atomic number 40 and symbol ZR. It is a very hard metal resistant to corrosion and very similar to the steel. The zircon has been used mainly in the lining of nuclear reactors, in the chemical industry, in jewelry, manufacture of cutting blades, etc.
The zirconia crown – a solution ultramodern and super efficient to replace the missing teeth, he will smile more often, and the other will be left dumbfounded.
The zirconia crown was used for the first time in 1998 in the dental clinic at the University of Zurich (Switzerland), and since then its popularity increased continuously.
The zirconia crown is also called crown of zirconia, crown of zirconia oxide, zirconia sheath, teeth of zirconia.
The material used in the manufacture of zirconia oxide crowns
Many patients because of the name, believe that the target is done completely in zirconia. But, in reality, only the inner part is made of this material, however, the external part is carried out in ceramics. The combination of these materials offers the teeth a high resistance and an aesthetic quality that cannot be compared with other types of dental crowns.
The crown in zirconia has the following advantages:
A bridge in zirconia ceramic and plaster models. The crowns of zirconia leyeras are more than a metal-ceramic but up to 50% more resistant;
The zirconia oxide dental is absolutely compatible with the human body. It is not a metal and does not cause any type of allergy;
The white color of the zirconia allows the use of crowns for a longer period. With these crowns never the metal will be visible, even if it’s removed from the gum or breaks a piece of broken pottery;
The zirconia crown limit the adhesion of the dental plaque;
The zirconia oxide is not transparent to the light in comparison with the pure porcelain, so also the gray teeth when they are coated, they can become very aesthetic.
The crown of zirconia also has a low thermal conductivity (because it is free of metal parts), so you can eat hot food or cold without test unpleasant sensations due to temperature.
The disadvantages of the crown of zirconia:
The only downside to the crown of zirconia oxide is the high cost a lot more in comparison with the metal-ceramic or ceramic pure (see the prices of the dental crowns). This is due to the material that is expensive, to the technology of production very complicated and complex that requires dental prosthetic with appropriate skills and high.
The use of zirconia represents an important stage for the future of the esthetic dentistry. This material is very well accepted by each agency, integrates seamlessly into the smile of the patients and has been successfully used in many modern dental clinics to perform dental crowns zirconia a unbeatable esthetics.
This technique is becoming increasingly popular on a large scale in the sector of esthetic dentistry and his popularity will increase significantly.
