Porcelain Fused to Zirconia

Porcelain Fused to Zirconia

For truly superior aesthetics, Porcelain Fused to Zirconia is a great option in restorations because of the ideal room that they are able to give for veneering ceramic. As one of the most promising restorative materials, it is lighter in color, which allows it to be less of problem than with a Porcelain Fused to Metal Restoration. Our state of the art Zirconia-based restorations feature unparalleled craftsmanship and lead to very little in the way of gingival reaction.
