Light Transmittance of CreoZir T
High translucency and shade accuracy allows esthetics especially for the anterior region as an alternative to lithium disilicate.

Wear of Opposing Natural Human Enamel Surface on Zirconia
“The wear amount of enamel in this study was higher when enamel was opposed by veneered zirconia (0.6220 gm) mean weight loss in comparison to enamel opposed by full-contour zirconia (0.4004 gm) mean weight loss, this was due to the lower level of enamel hardness when compared to veneering porcelain, and because the fracture toughness of enamel is significantly lower than that of the veneering porcelain.”
