IPS E.max®

Lithium disilicate e.max is essentially a glass material ceramic material to mimic natural dentition without having to utilize porcelain veneering material which is often needed to achieve high esthetics. IPS e.max is an incredibly versatile material offered in an array of precolored ingots (glass blocks) and their corresponding opacity level. The material can be designed with full contour or porcelain layered in mind.
