摘要： PROBLEM TO BE SOLVED: To provide a device for producing a dental workpiece, machining a blank more favorably.
SOLUTION: The blank 13 is inserted in a substantially slab-shaped support body 10 of the device, and the support body is dimensioned such that the blank 13 does not extend beyond it in any direction. The blank 13 is linked with corresponding inner walls of a recess 12 provided in the support body 10 only on two opposite faces while a gap is left between the other inner walls of the recess 12 and the corresponding faces of the blank 13. Therefore, tensions and microcracks of the blank material caused thereby are allowed to be avoided. The gaps further make the blank 13 directly accessible for a lateral working by a milling tool.

摘要： The invention relates to a device for the automated production of dental workpieces. A blank is inserted in a substantially slab-shaped support of the device, said support being dimensioned such that the blank does not extend beyond it in any direction. The blank is linked with corresponding inner walls of a recess provided in the support only on two opposite faces while a gap is left between the other inner walls of the recess and the corresponding faces of the blank. The inventive design allows to avoid tensions and microcracks of the blank material thereby caused. The gaps further make the blank directly accessible for a lateral working by the milling tool.

摘要： The present invention relates to a glass filler material with an average particle size of 0.1 - 20 mu m. It further relates to a method for producing a glass filler material. The glass filler material comprises 65 - 99.95 mol% silicon dioxide (SiO2), 0 - 15 mol% aluminum and/or boron oxide (Al2O3, B2O3), 0 - 30 mol % zirconium and/or titanium and/or hafnium oxide (ZrO2, TiO2, HfO2), Y2O3 and/or Sc2O3 and/or La2O3 and/or CeO2 and/or other lanthanidoxides, 0.05 - 4 mol% alkali metal oxides (Na2O, Li2O, K2O, Rb2O, Cs2O), 0 - 25 mol% earth alkali metal oxides (MgO, CaO, SrO, BaO). The glass filler material shows a low concentration of alkali ions and is used for composites with cationically curing properties and for dental composites and dental restoration materials.

摘要： The invention relates to the use of ions of weakly basic oxides as linking ions for polyacids in cements, preferably polyelectrolyte cements. Suitable ions comprise elements of the scandium series, for example, Sc 3+ , Y 3+ , La 3+ , Ce 4+ and all subsequent tri- and tetra-valent lanthanides and the ions Mg 2+ , Zn 2+ , Ga 2+ , In 2+ . The application of said ions permits a regulation of the cement reaction without surface treatment of the glass powder.
