Abstract: A curable and radiopaque substance, a material that can be produced from same via polymerisation, a method for producing the curable substance and the cured material, and the use of the curable substance or the cured material are disclosed. The curable substance or the cured material can be used in, inter alia, orthopaedics as so-called bone cement, in particular as a tooth filling material, dental cement, dental lining material, flowable composite material (flow material) etc., as well as in diagnostic radiology. The invention also relates to the use of the curable substance generally as a construction material in an additive manufacturing process using a digital data model.

Abstract: The invention relates to a milling block (1) for producing partial or total prostheses, comprising a prosthesis base (3) to be processed according to the shape of the jaw, on which synthetically moulded teeth (5), preferably a full set of teeth, are provided, a milling block system consisting of a first milling block for the upper set of teeth and a second milling block for the lower set of teeth, and a method for producing partial or total prostheses.

Abstract: A method for positioning a semifinished product, has the steps of: providing a semifinished product having at least one position mark aligned with the center of contraction or expansion, and providing a machining device for machining and finishing the semifinished product, which is positioned, preferably reproducibly positioned, in the machining device via fastening means and the position mark.

Abstract: The invention describes a device for positionally fixing a moulding comprising a base surface having at least one fixing element for the moulding, characterized in that at least one positioning means is provided which interacts with the fixing element, and the moulding has at least one position marking which interacts with the positioning means.

Abstract: The invention describes a polymerisable mixture composition containing a liquid or semi-solid component A with at least one monomer portion and one, preferably powdery, solid component B on a polymethyl methacrylate (PMMA) base with a filler and/or additives, the liquid or semi-solid component A additionally having at least one oligomeric or polymeric compound modifying the monomer portion and which is miscible with the monomer portion. Furthermore, use of the mixture composition and a moulded part, for example a dental prosthesis, produced from the latter, is specified.

Abstract: A method for producing a blank for a permanent dental crown starts with a blank that includes a tooth module and a support. A preparation is formed on the underside and serves for connection to an anchoring element such as a screw element or tooth stump. The tooth module and the support are produced from the same material in a first process that permits a high surface quality. In a second process, the tooth module and support are connected to one another and can then be further processed. This method leads to a high dimensional stability of the resulting crown and permits the use of inexpensive plastic material for a high-quality permanent dental prosthesis.

Abstract: A process for producing a dental prosthesis includes producing a wax prosthesis including artificial teeth and a receiving bed for articulating the artificial teeth by inserting the artificial teeth into the receiving bed at anatomically correct positions, producing a negative mold of the wax prosthesis using a duplicating medium, removing the receiving bed, introducing a fixing material into the negative mold, and allowing the fixing material to set, so that the undersides of the artificial teeth are permanently embedded in the fixing material. The artificial teeth have a holding groove running in a mesio-distal direction on its underside, so as to produce reliable positively locking joining of the artificial tooth to the receiving bed of the wax prosthesis.
