Offering esthetics, strength and durability, the IPS e.max system covers a wide range of indications for nearly any clinical situation. IVOCLAR VIVADENT expands the use of IPS e.max with the new IPS e.max CAD-on. This laboratory-produced, two-piece restorative technique uses high-strength zirconia for a substructure and highly durable IPS e.max CAD lithium disilicate for the veneering structure. The two pieces are joined by a unique fusion ceramic to create a restoration that has the esthetics and wear compatibility of lithium disilicate and the strength of zirconium.
