Abstract: A radically polymerizable material for the preparation of dental prostheses, containing (a) at least one monofunctional radically polymerizable (meth)acrylate, (b) at least one polyfunctional radically polymerizable (meth)acrylate, (c) at least one ABA triblock copolymer, (d) at least one nanoparticulate or microfine filler having an average primary particle size of from 10 nm to 350 nm, and (e) at least one photoinitiator. The A block of the ABA triblock copolymer is an oligomeric polyester and the B block is an oligomeric polysiloxane.

Abstract: A method is provided for producing a dental prosthesis from a blank using a CAD/CAM device, wherein the blank consists partially of base material and partially of tooth material, and a boundary surface between these materials is formed as a wave, the wave crests and wave valleys of which alternate with each other along the outer periphery of the blank. The apex of each wave crest extends substantially radially with respect to the blank. The CAD/CAM device fixes the position of a retention part, which serves to fasten the prosthesis to the alveolar crest of a patient, in particular of an external telescope, of a cover of a bar, or of an abutment in the prosthesis in such a way that it passes through the boundary surface. The retention part is fastened by means of gluing or incorporation by polymerisation.

Abstract: A semi-finished product as a pre-product for a dental prosthesis having a prosthesis base, wherein the prosthesis base comprises at least one dental recess for receiving a set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension. It starts at an adhesive filling opening whose configuration is adapted to a filling element.

Abstract: A dental prosthesis having a prosthesis base and a set of teeth, namely a full set of teeth or a partial set of teeth, is provided, wherein the prosthesis base comprises at least one dental recess for receiving the set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension.

Abstract: The present invention relates to a stereolithography method, comprising the steps of receiving a light-curing suspension (100) comprising filler particles (103) in a tray (105); adjusting the light-curing suspension by means of a build platform (107) to a layer thickness with respect to a bottom (109) of the tray (105) which is less than the diameter of the filler particles (103); and selectively curing the adjusted layer thickness of the suspension by means of light.

Abstract: The present invention relates to a method of producing a dental object (100), comprising the step of producing a support structure (101) on the dental object (100) having a predetermined breaking point (103) arranged such that a residual portion (105) of the support structure (101) remains on the dental object (100) after the predetermined breaking point (103) is separated.

Abstract: A partial dental arch is provided with dentin material and with cutting material and a boundary area therebetween. It includes a primary-position tooth region and additional tooth regions which are arranged more distally. A wavy structure of the boundary area is provided whose amplitude—when viewed in the distal direction—decreases in at least one section of the mesial-distal and/or occlusal-gingival extension, in particular with regard to the occlusal-gingival direction.

Abstract: A dental multi-colored milling blank having at least two layers (16), a transition zone, where material from both layers is present. In the transition zone, a transition geometry exists that extends three-dimensionally. The transition geometry comprises round surfaces facing towards both directions of extension of the layers.

Abstract: Monochromatic dental shaped body, which has an opacity of from 70 to 78%, and a process for its production.

Abstract: Positive models of a prosthesis base or partial prosthesis base are produced additively or generatively in 3D printing using a dental prosthesis manufacturing process. The model is then encapsulated with a curing negative mold production material, in particular plaster. In the next step, following curing of the casting material, the positive model is removed by heat. The negative mold of the base is filled with prosthetic material and is cured. The positive model is subsequently applied to the base and embedded together with it. The positive model of the dental crown is then removed. The resulting free space is filled with tooth material by injection.
