Abstract: The present invention relates to a dental prosthesis molding block (10) for producing a dental prosthesis part. The block comprises an inner material (13) that is at least partially surrounded by an outer material (14), the hardness of which differs from the hardness of the inner material (13). The inner material (13) forms part of a first surface (11) of the dental prosthesis molding block (10). The invention further relates to a method for producing a dental prosthesis part. In said method, a dental prosthesis molding block (10) is provided, and the dental prosthesis part is produced by removing material from the dental prosthesis molding block (10) using a CAD/CAM process. In doing so, a pin having a self-tapping external screw thread is created.

Abstract: A method of manufacturing a dental restoration including a construction step (S2) of preparing construction data for a dental tool machine for machining the dental restoration from a workpiece. The construction data defines at least the geometry of the dental restoration within the workpiece. The method includes a starting step (S3) of starting machining of the dental restoration from the workpiece in accordance with the construction data. The method also includes a preparing step (S4) of starting preparing, before termination of the construction step (S2), the dental tool machine at least through equipping it with all the consumables essential for starting the starting step (S3), and completing preparing the dental tool machine before start of the starting step (S3).

Abstract: The invention relates to a sintering furnace for components consisting of sintering material, especially dental components and in particular components consisting of ceramic, and a method for sintering such components. The sintering furnace 1 comprises a heatable furnace chamber 2 for the component 9 to be sintered, the furnace chamber 2 having a wall section 6 to be opened for inserting the component 9 to be sintered into the furnace chamber 2. Drive means 10 are provided for mechanized opening and closing of the wall section 6, and a control 11 is provided for the drive means 10 that has an actuation element 12 for the drive means 10. Furthermore, a heating device 5 for the furnace chamber 2 is provided, and the control 11 causes the furnace chamber 2 to be heated. Actuating the control element 12 triggers the loading sequence of the control 11, and the drive means 10 are automatically actuated by the control 11 corresponding to the loading sequence. An additional subject is a method for operating the sintering furnace, as well as a computer program therefor.

Abstract: A carrier for at least one fastening element (4) to be fabricated having an attachment area whereby the carrier is provided with a holding piece (3) for attachment in a receiving part of a finishing machine and whereby the carrier includes a carrier piece (2) for the fastening element (4) and the carrier piece (2) is embedded at least partially in the carrier piece (2) in a manner so that the attachment area (4b) of the fastening element (4) can be fabricated. A method for producing a fastening element (4) to be finished and to be attached to an individual surface whereby the contour of the attachment area is defined with the aid of data of the surface onto which the fastening element (4) is to be attached and whereby a pre-shaped, not yet individualized fastening element (4) is formed by removal of material to produce the specific contour. Furthermore, an auxiliary positioning part (21) is provided with a contour that is continued by the contour of the attachment area, which is also defined by the surface onto which the fastening element (4) is to be attached.
