摘要： The blank is used to manufacture parts in a processing machine with at least two tools in the operating chamber of the machine. The blank has a body (1) of dental restoration material, from which the part can be formed by material removal using at least one of the two tools. The blank has at least two gages (4,5) each in the form of a recess. The geometry of the recesses is such that the tool selected for the process is identifiable with at least one of the gages by its outer contour. The gages are arranged on the blank such that two tools can be driven into them simultaneously when the blank is fitted into the machine for processing. Independent claims also cover a method of manufacturing dental components.

摘要： PROBLEM TO BE SOLVED: To provide a dental CAD/CAM system to assist operators to create prosthetic dental items having superior mechanical properties.
SOLUTION: The dental CAD/CAM system performs structural analyses of a candidate prosthetic dental item that is to be created using design data representing the prosthetic dental item, and can recommend positioning of a surface of the prosthetic dental item within a volume of a milling block based on the design data (S302) and data representing desired aesthetic properties of the prosthetic dental item (S306). The dental CAD/CAM system can generate and display simulated images of the aesthetic properties of the prosthetic dental item using the design data, data representing the surface of the prosthetic dental item, data representing the volume of the milling block, and data representing aesthetic properties of the milling block (S314, S318). The dental CAD/CAM system can be used to form prosthetic dental items having complex aesthetic properties, such as translucent regions and shades of colors that vary spatially.

摘要： A method for detecting and representing one or more objects, such as teeth, their preparations and their immediate environment, using a camera. A first recording is made wherein a still image is produced. The still image is blended into a current, mobile search image in at least one sub-area in the second step, so that both images are recognizable. In the third step, the camera is positioned in such a way that the search image overlaps the blended-in still image in at least one sub-area. The second recording process is initiated in a fourth step.

摘要： A blank for producing a formed dental part has closely toleranced reference faces being arranged at one end of a blank member lying opposite a retainer projection. The reference faces comprise two surfaces lying opposite one another that have a defined spacing from one another with close tolerances. The surfaces are advantageously formed by a reference part with a cylindrical cross section that is secured onto the blank member.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for determining actual position data on a machining tool by an actual article in a manufacturing field of a tooth recovering passive body by using a grinder of a CAD/CAM grinding machine of dentistry. SOLUTION: The tool is brought near to a reference surface 10 of a workpiece 8 or a part body 9 joined to the workpiece by adjusting a rotational speed of the tool such as a stopping rotation of the tool 1 by a friction load with the workpiece to a measurable low rotational speed, the reference surface is relatively moved along the tool before the contact of the tool and the reference surface or at a contact time, and an actual position of the reference surface is determined by an asymmetric characteristic of a contact surface formed on the reference surface in so doing.
