Do you want to learn about Zirconium Crowns to discover if zirconium crowns are the right choice for you?
Zirconium also called Zirconia (Cercon) is rapidly becoming the material of choice for dental crowns. It is a very strong material able to withstand the wear and tear of every day use. Aesthetically, it is translucent very similar to a natural tooth, reflecting light in much the same way. This means that Zirconium, Zirconia has a very aesthetic effect, which may be important if your new crowns are to be at the front of your mouth and is particularly relevant in cases where the crowns will be seen beside natural teeth. • Metal free from our own Dental Laboratory • High translucency • No black margins • Extremely solid • Absolutely metal free • Excellent biocompatibility These are the porcelains in which we attain a more aesthetic appearance thanks to the white colored alloy that is used instead of metal as infrastructure. Thus, prosthesis assumes an aesthetic appearance that is much closer to natural teeth. It reflects light and it doesn’t reflect a dark color line on the gingiva level since the infrastructure is made of white colored alloy. It is in complete harmony with human body and doesn’t cause allergy. Since zirconium supported porcelains feature a high resistance of 900 megapascal, they can be comfortably used on the posterior molar teeth either. This is a state-of-the-art technology that is so aesthetic and elegant to permit light in addition to its strength. The preparation of zirconium supported prosthesis is the same as the alternatives. The difference starts only at the laboratory phase. Such prostheses are produced by computer assisted devices featuring CAD CAM technology. The patient is scanned by means of optical readers with the measurements taken from the mouth and shaped by milling cutter systems without touch of hand. The data that is formed with the help of cameras is loaded on the computer and designs (CAD) are obtained and produced (CAM).
What exactly is Zirconium?
In the most simplest terms: Zirconium is obtained mainly from zircon mineral and it is a component that has a hardness similar to copper and is lighter than that of a steel.
Why choose Zirconia crowns ?
Zirconium/ zirconia is biocompatible, non allergic, non electrical conductive material with the unique specification of letting light pass through so that the crown appears to be a natural tooth. Zirconinum/zirconia also provides the extra comfort that it would not break or chip over a period of time as against a full porcelain crown to which this is occasionally known to happen. Porcelain is the traditional material used for new crowns. Full porcelain however may chip or break. This is overcome by making the crowns from metal, in this case the metal being zirconia, then fusing porcelain to the outside. The zirconia metal provides the strength whilst the porcelain provides the outward appearance on a normal tooth. Zirconium crowns allow light to pass through as with a normal tooth giving a natural look, unlike other metal cores which block the light. Some resources are also calling them as Non-Allergic Crowns and say Zirconia is”Biocompatible” because the body does not reject it. Unlike Amalgam Fillings and metal alloys, the human body accepts zirconium, zirconia as a natural material, so you would not need to worry about allergies or adverse reactions.
