Advanced zirconium-based crowns are taking place of ordinary metal and porcelain crowns. The advantage of this combination is natural translucency of the crown, which makes it possible to successfully copy a natural tooth. Zirconium dioxide is rightfully called white gold in dentistry, because such crowns are biocompatible with mouth tissues. Zirconium dioxide is often used for anterior teeth because due to this material the metal base could not be seen in the ray of light. We all get to know that a person has metal ceramic crowns because when smiling we can spot unsightly dark edge, which gives the owner of metal ceramics away. But no one will notice you have crowns if your crowns are made from zirconium dioxide, because it offers the best dental aesthetics possible. Due to its anti-allergenic properties, we can eliminate all sorts of complications or reactions with other metals (structures) in the oral cavity. Another important argument is the durability of a crown compared to all-ceramic crowns, which also have good aesthetics, but are totally unacceptable for the posterior teeth. Zirconium dioxide is the gold standard in dental prosthetics.
