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 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 dental prosthesis is provided, manufactured from a one-piece or multi-piece prosthesis blank which is composed of a gum-colored material (14) and a tooth-colored material (14), especially each one being based on plastic material. The tooth-colored material (14) of the blank (10) has a diameter or a width of more than 5 cm and especially a substantially flat cylindrical shape with a diameter/height ratio of more than 2:1, preferably more than 3:1. The gum-colored and tooth-colored materials (14, 12) are bonded together by bonding, polymerization and/or integral production. The boundary (16) between the materials, as viewed in the direction of the dental arch course, is wave-shaped with alternating grooves and ribs (22, 24), and in the region of the anterior arch in the vestibular direction—is of radiant shape.

Abstract: A manufacturing device is provided for the production of a blank, in particular one which is to be polymerized, of a dental restoration part. A mold for receiving blank material includes in particular a pot-shaped or cup-shaped base and a punch or—possibly hood-shaped—cover. An insert body with a structure on its underside and a heating device for the mold and a control device for the manufacturing device are provided. A height measuring device is connected to the control device, which measures the height of a reference surface connected to the punch or cover, relative to the base. The control device calculates the height position of the structure based on this measured height.

Abstract: A dental prosthesis is provided, manufactured from a monobloc or multibloc prosthesis blank (10), which is composed of a gum-colored material (14) and a tooth-colored material (12), which materials (12, 14) are bonded to each other by bonding, polymerization and/or one-piece manufacture. The boundary surface (16) between the materials is wave-shaped comprising alternating grooves (22) and ribs (24) in the course of the dental arch, and radial in an oral-vestibular direction in the region of the anterior teeth (33) to be created. The boundary surface (16), at least in the region of the molars (26)—again as viewed in the oral vestibular direction—has parallel grooves (22) and ribs (24) forming troughs and crests of the waveform, or grooves (22) and ribs (24) such that they extend in deviation from parallel by at most 10 degrees, in particular at most 5 degrees, at least in the region of the molars (26).

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.
