Zirconia crown consists of zirconium which is a white-colored mineral. This mineral is transformed into zirconia ceramic using special procedures.
Zirconium porcelain is made up of zirconia core and porcelain layers. Zirconia crowns have a high light permeability, therefore, they resemble normal teeth structure and more aesthetic and natural.
For this reason, it is mostly used in aesthetic dentistry instead of metal-infused porcelain crowns.
They are harmonious with the gums and have a less chance to cause gum disease than metal infused crowns. In recent years monolithic zirconia crowns have been introduced. These crowns do not have a porcelain layering. They are fully made up of zirconia blocks, therefore, stronger in the core.
