The super translucent multilayer blanks are intended for the manufacture of veneers, inlays, onlays, monolithic crowns for frontal prosthetic dentures, crowns for abutments, bridges up to 3 units.
The translucency of the blanks is comparable with that of lithium disilicate.
The multilayer blanks consist of several layers colored in accordance with the VITA® scale, with smooth transition between these layers from dark to light.
