Zirconium Crowns



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.

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.
