Abstract
The invention relates to a method for the production of a restoration from a blank consisting of, or containing, a lithium silicate glass ceramic, wherein at least two layers of ceramic material of different compositions are filled into a mold layer-by-layer and after filling of the layers they are then pressed and sintered, wherein after filling of a first layer this is structured on its surface in such a way that the first layer, viewed across its surface, differs in its height from region to region, and then a layer with a composition that differs from the first layer is filled as a second layer into the mold. After sintering the dental restoration is produced from the blank by mechanical working.
