Zirconium crowns are high-tech restorations prepared by processing porcelain on a zirconium dioxide infrastructure, which does not contain metal support, unlike traditional porcelain crowns.
The biggest advantage of zirconium is that it is both very durable and can transmit light like natural tooth enamel. In this way, artificial and gray reflections created by metal-supported porcelains do not occur, especially in the front teeth.
It is a biocompatible material that perfectly harmonizes with the gums. Even in case of gum recession, the black line formation seen in metal crowns is not seen in zirconium.
