Abstract: Method, system and computer program product for processing planning-relevant data sets, in which planning-relevant data sets from different tables of at least one databank with operative planning data are input into a central table which comprises a central quantity field and/or a central date field, and on the basis of the central table obtained a multi-dimensional data cube is generated and stored in a central memory of a network system, and wherein, for evaluation, the multi-dimensional data cube is loaded from the central memory into a front-end application.

Abstract: The artificial tooth blanks made by series production involve a dentin-colored fired dental ceramic composition including a previously compression-molded hard core and optionally a retention, wherein the size of the artificial tooth blank is reduced over that of the corresponding finished artificial tooth and the artificial tooth blanks do not contain an enamel layer. The retention may involve one or more high-melting shells incorporated by firing and containing high-melting retention pins soldered therein after firing, wherein the retention pins as well as the solder are stable under the melting conditions for dental ceramic compositions for bridges and crowns, and especially so in the presence of air as well.
