IPS e.max: an innovative all ceramic system

Prescribe IPS e.max to achieve optimal esthetics, virtually perfect contacts and occlusion, and impressive strength. This unique lithium disilicate ceramic formulation provides an average flexural strength of 500 MPa, making it the ideal high-strength solution for single-unit anterior or posterior crowns, veneers, inlays, onlays, screw-retained implant crowns, 3-unit anterior bridges, or restorations with minimum preparation dimensions. Conventionally cement using resin ionomer cements or bond for maximum retention on non-retentive preparations. IPS e.max is biocompatible and provides more than three times the flexural strength of IPS Empress® Esthetic.
