"State of the Art" Zirconia material. Stronger at the base, it transitions to a softer Zirconia at the occlusal surface, reducing the abrasion and wear on opposing dentition. Ideal for single crowns or bridges for both anterior and posterior restoriations. Maxzir Zirconia is a brand new blend of Zirconia released in 2016. It's design allows for the translucency level to appear natural as it increases throughout the crown from the base to occlusion.
