IPS e.max CAD is an innovative lithium disilicate glass-ceramic (LS₂) block for the CAD/CAM technology.

IPS e.max CAD blocks are suitable for the efficient fabrication of esthetic high-strength single-tooth restorations, such as veneers, inlays, partial crowns and crowns. In combination with IPS e.max ZirCAD (ZrO₂), the innovative IPS e.max CAD-on technique now also permits the fabrication of up to 4-unit posterior bridges with outstanding overall strength.

The IPS e.max CAD lithium disilicate (LS₂) glass-ceramic is processed in a "soft" intermediate state, in which the material demonstrates its characteristic and striking bluish colour. In this way, manual adjustments or a cut back can be quickly and efficiently carried out and the accuracy of fit can be checked.

This is followed by a simple and quick crystallization process (approx. 20 min), in which the material obtains its final strength of 360 MPa and the desired esthetic properties, such as tooth shade, translucency and brightness. IPS e.max CAD can be designed to full contour or used to fabricate frameworks (veneering with IPS e.max Ceram).

HT blocks (High Translucency)

The HT blocks are available in 16 A-D and 4 Bleach BL shades and 2 sizes (I 12, C 14). Given their high translucency, these blocks are ideally suitable for the milling of smaller restorations (e.g. inlays, onlays). Restorations made of HT blocks convince users with their true-to-nature chameleon effect and the exceptional adaptation to the remaining tooth structure.

LT blocks (Low Translucency)

The LT blocks are available in 16 A-D and 4 Bleach BL shades and 2 sizes (I 12, C 14). Given their low translucency, they are particularly suitable for the fabrication of partial crowns and single crowns using the cut-back and also the staining technique. The lifelike esthetic appearance can be maximized with the final layering with IPS e.max Ceram Essence and Shade materials.  

IPS e.max CAD Impulse blocks

IPS e.max CAD Impulse blocks are available in three Value (Value 1, 2, 3) and two Opal shades (Opal 1, 2) and one size (C14). They are mainly used to fabricate (thin) veneers as well as single and partial crowns.

The Value blocks feature different brightness values: 1 is the lowest and 3 the highest. Thus, the tooth shade may either be individually adjusted to a given brightness value or a consistent brightness may be achieved in the case of a differing shade of the prepared tooth. The Opal blocks offer decreasing levels of opalescence coupled with increasing brightness values from 1 to 2. The unique opalescence and strength make the Opal blocks ideal for “enamel replacement”.

MO blocks (Medium Opacity)

The MO blocks are available in 5 group shades (MO 0 - MO 4) and one size (C 14). Given their opacity, they are ideally suitable for the fabrication of frameworks on vital or slightly discoloured preparations. The anatomical shape is subsequently individually layered using IPS e.max Ceram.
