摘要： The invention relates to an automatic machine tool (10), for the production of base structures (68), for false teeth, in particular, for tooth crowns and/or tooth bridges of exact three-dimensional shape. Said base structures (68) may be fixed to prepared natural and/or artificial tooth stumps. The machine tool (10) comprises a machine frame (12, 14), or a body, a work piece carrier, with a rotation shaft (38), at least one digitisation unit (46), at least one machining unit (52) and an electronic arithmetic and control unit (50) for all drive lines. A carrier for the workpiece, a blank (42), and/or for the machining unit(s) (52), serves as displacement unit, with three translational axes in the x-, y- and z-directions. The digitisation of the preparation model (44) and the machining of the blank (41) are carried out on the same machine tool (10), at different times. The machining paths for the blank (42) are calculated from the measured and stored digitised data and a predetermined material-specific scaling factor, before the machining of the blank.

摘要： The invention relates to a holding device (56) that can be braced in a surveying machine together with an individual preparation model (22) produced by dental laboratory techniques. The holding device (56) has a mechanically stable frame (10) with bores (12) disposed at a distance (a) to one another, in which at least two holding pins (18) are locked that can be displaced at least in the axial direction (A). The holding pins (18) are linked on the front thereof with the preparation model (22) that is free of undercuts by means of a primer (34) and they fixate the model rigidly and without tension in the frame (10). The loaded frame (10) can be braced in the surveying machine by means of a machine-side bracing adapter (16) in an anti-skid and rotationally fixed manner. The preparation model (22) and the frame (10) are fixated outside the surveying machine. The number and position of holding pins (18) is determined, the pins are inserted in the respective bores (12), the primer (34) is applied to the front of the pins and the pins are placed on the surface of the preparation model (22) and all holding pins (18) are locked so that they cannot be displaced or rotated. The loaded holding device (56) is exposed once the primer (34) is cured.

摘要： A holding device (42) comprises a cylindrical or prismatic, porous ceramic blank (10) and means for clamping in a machine tool for processing the blank (10) by removing material, in order to produce a ceramic workpiece (18). A narrow frame (12) is fixed by an adhesive connection over at least part of the periphery of the blank (10), which is held without stresses, in the area of a plane encompassing the longitudinal middle axis (A) of the blank. Said frame (12) only covers a small part of the surface of the blank (10) and can be detached and held in a stable holder (24) with a clamping adapter (34), in such a way that it cannot slide. The entire combination is fixed in the machine tool in such a way as to be resistant to twisting and sliding. The ceramic workpiece (18) emerges continuously from the ceramic blank (10) without predetermination of the advance direction, until holding segments (20) which can then only be freely selected according to number and location have been formed. Said holding segments (20) end on the residual material of the blank in the area of the frame (12) or on the frame (12) itself. The holding device is used especially as a workpiece (18) for producing fully ceramic dental prostheses, particularly crowns or bridges.
