Abstract: A tool for the internal high-pressure shaping of a workpiece, in particular for producing a tubular structural component for a motor vehicle, is provided. The tool includes at least three movable tool segments, which bound a shaping cavity for accommodating and shaping the workpiece. The movable tool segments, at least in some sections, completely form the shaping cavity in a closed state of the tool. A method for shaping a workpiece by internal high-pressure shaping is also provided.

Abstract: A process for determining a tooth color of a filling or another restoration is provided which in particular is produced using composite materials, wherein at least one tooth is scanned or is visually detected. The process is characterized in that natural teeth are spectrally measured in advance, that the color values measured within a color space are classified into several, in particular four, categories which each form a color cloud extending in a three-dimensional fashion within the color space, which is done with the help of a structuring algorithm, in particular a Nearest Neighbour Algorithm, or a symmetry recognition algorithm, and that the tooth color of the filling is determined by means of evaluating to which category the tooth scanned has the smallest color distance, or to which color cloud the tooth scanned belongs.

Abstract: A system having an auxiliary color selection body and a method for determining the colors of a dental object, i.e. the colors of tooth, residual limb or gingiva, is provided, wherein the auxiliary color selection body (10) has a substantially U-shaped or L-shaped or ring-shaped structure, on which at least one, preferably 4, reference features (18), for recognition of the auxiliary color selection body (10) is/are attached, and wherein, with respect to the reference features (18), a plurality of tooth, stump or gingiva color fields (30) are arranged on the color selection auxiliary body (10). It is provided for an image of a tooth (16) to be taken with the auxiliary color selection body (10) being adjacent thereto on at least two sides and the tooth color is determined based on this image (FIG. 1).

Abstract: An auxiliary color selection body (10) is provided for target objects (34) such as dental objects, having a base body. The base body (12) has at least two inner walls (16, 18, 20) which extend transversely, in particular at right angles to each other, from which inner walls the base body extends outwardly as far as to the outer walls (22). The base body (12) extends in two dimensions between the inner walls and the outer walls, with color selection areas (30) and reference features (32) arranged on the auxiliary color selection body. The auxiliary color selection body can be arranged in the vicinity of a target object (34) such that a straight line passing through two target object proximity points (38, 40, 42) on the inner walls sweeps across the target object.

Abstract: A system of a dental restoration part or several dental restoration parts, and/or with a dental restoration part which is possibly embedded in a muffle, and a cooling device is provided. The cooling device comprises cooling bodies as bulk material and a movement device by means of which cooling bodies and the dental restoration part(s) may be moved relative to one another.

Abstract: A tool is provided for preforming a metallic starter tube section for subsequent internal high pressure forming in order to produce a tubular IHF-component. The tool includes a plurality of tool sections that can move relative to one another and that delimit, between them, a shaping cavity for receiving and forming the starter tube section. The cavity has a contour which is both derived from the shape of the IHF component to be produced and adapted to the circumference of the starter tube section to be formed, such that each cavity cross section perpendicular to a cavity longitudinal axis predefined by the starter tube section corresponds to the cross-sectional shape of the IHF component cross-section in the same position, reduced in its cross-sectional circumference to exactly the circumference of the starter tube section. A method is provided for producing such a tool, and a method is provided for producing a tube-like IHF component using such a tool.
