IPS e.max CAD (lithium disilicate) exhibit

superior durability featuring 360 MPa of

flexural strength.

When fabricated to full-contour, the

monolithic structure is the most robust

ceramic crown tested to date.

360 MPaflexural strength

IPS e.max CAD Lithium disilicate (LS2)


5/65

Lithium disilicate combines high strength and high esthetics

Broad indication range because of the high strength of 360 MPa

depending upon on the indication Lithium disilicate offers flexibility when

it comes to cementation

Various translucency levels and a comprehensive shade range allow

versatile esthetic options



6/65

Innovative, unique lithium disilicate (LS2) glass ceramic

IPS e.max CAD is milled in the intermediate state blue state

easy, quick and pecicely milling

The material strength and the esthetic properties are reached by a

fast and easy crystallization process
