Dental Zirconia itself is not just the compound zirconia dioxide, it actually has a mixture of properties. Most zirconia is comprised of “zirconia” (ZrO2) and “yttria” (Y2O3), which is commonly called Yittria-stabalized Zirconia (a zirconium-oxide based ceramic, in which the particular crystal structure of zirconium oxide is made stable at room temperature by an addition of yttrium oxide.) Dental Zirconia is created into a shape by the manufacturers to work in a specific type of milling machine. Our Lab then uses CAD/CAM or other means of shaping a coping or a Full zirconia crown to fit to the die or model for the layering of ceramic glass. One of the key benefits of using zirconia instead of metal, is the bio-compatibility in the patient. There is no metal involved so there is no allergic reaction that can be caused by the crown itself. Another benefit is the fact the crown becomes much more translucent and lifelike, unlike metal which masks out the entire tooth structure, zirconia brings out the color in the tooth and overall enhances the crown itself. If you have not ordered a Porcelain Fused to Zirconia crown before, we urge you to try one and guarantee you will much happier with the results than a standard PFM.
