Leucite-reinforced glass ceramic blocks for the efficient fabrication of all-ceramic single-tooth restorations using CAD/CAM technology. Apart from blocks with high and medium translucency, polychromatic blocks with a natural gradation of shade and fluorescence are offered, which do not require additional characterisation. After wet grinding in a PrograMill milling machine, the glass ceramic - with its outstanding light-optical properties (flexural strength of 185 MPa) - only needs to be polished. Alternatively, IPS Empress CAD restorations can be either characterised with stains or veneered using layering materials. Starter Kit contains Blocks HT A2 I12 x 5, Blocks LT A2 C14 x 5, Multi A1 C14 L x 5, Multi A2 C14 L x 5, and IPS Natural Die Material Shade Guide.
