IPS e.max is a high strength (360 MPa) lithium disilicate glass-ceramic (LS2) for the CAD/CAM technique directly in the dental office (chairside) or the laboratory (labside). Its indication spectrum includes inlays/onlays, thin veneers, occlusal veneers, crowns, anterior/premolar bidges, implant superstructures as well as hybrid abutments and hybrid abutment crowns. In the fabrication of long-span bridges - also for the posterior region - IPS e.max CAD veneering structures are used in combination with zirconium oxide frameworks. IPS e.max CAD blocks are available in four levels of translucency (HT, MT, LT MO).
The MT blocks are available in the shades A1, A2, A3, B1, BL2, BL3 and BL4. These medium- translucency blocks are used in cases where a brighter look is needed than that imparted by HT blocks and more translucency than with LT blocks. Due to the ideal balance of brightness and translucency, MT blocks are ideally suitable for the fabrication of anterior restorations. Customization is achieved by means of the staining or cut-back technique.
