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: 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: 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: The invention relates to a dental prosthesis comprising a prosthesis base and teeth which are attached in or to the prosthesis base (14), wherein the prosthesis base (14) comprises a ventilation element, in particular a ventilation valve (12).

Abstract: The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.

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.

Abstract: A method for manufacturing a dental restoration part according to patient-specific requirements is provided, which dental restoration part comprises a prosthesis base, wherein the prosthesis base carries at least one prefabricated artificial tooth, in particular a large number of prefabricated artificial teeth. It is also intended for the prosthesis base to have a surface on the side facing away from the prefabricated artificial teeth, i.e. on the side opposite thereof, and a three-dimensional layer of material to be applied to this surface of the prosthesis base using a three-dimensional additive method, by which the prosthesis base will be fabricated according to the patient-specific specifications.
