    • The invention relates to an automatic machine tool, for the production of base structures, for false teeth, in particular, for tooth crowns and/or tooth bridges of exact three-dimensional shape. Said base structures may be fixed to prepared natural and/or artificial tooth stumps. The machine tool comprises a machine frame, or a body, a work piece carrier, with a rotation shaft, at least one digitization unit, at least one machining unit and an electronic arithmetic and control unit for all drive lines. A carrier for the workpiece, a blank, and/or for the machining unit(s), serves as displacement unit, with three translational axes in the x-, y- and z-directions. The digitization of the preparation model and the machining of the blank are carried out on the same machine tool, at different times. The machining paths for the blank are calculated from the measured and stored digitized data and a predetermined material-specific scaling factor, before the machining of the blank.
    • 本发明涉及一种用于生产用于假牙的基础结构的自动机床,特别涉及具有精确三维形状的齿冠和/或牙桥。 所述基底结构可以固定到制备的天然和/或人造牙齿树脂上。 该机床包括机架或主体,具有旋转轴的工件托架,至少一个数字化单元,至少一个加工单元和用于所有驱动线的电子运算和控制单元。 用于工件,坯件和/或用于加工单元的载体用作位移单元,具有在x,y和z方向上的三个平移轴。 准备模型的数字化和坯料的加工在不同的时间在同一台机床上进行。 在加工坯料之前,从测量和存储的数字化数据和预定的材料特定比例因子计算坯料的加工路径。

    • A holding device comprises a cylindrical or prismatic, porous ceramic blank and elements for clamping in a machine tool for processing the blank by removing material, in order to produce a ceramic workpiece. A narrow frame is fixed by an adhesive connection over at least part of the periphery of the blank, which is held without stresses, in the area of a plane encompassing the longitudinal middle axis (A) of the blank. The frame only covers a small part of the surface of the blank and can be detached and held in a stable holder with a clamping adapter, 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 emerges continuously form the ceramic blank without predetermination of the advance direction, until holding segments which can then only be freely selected according to number and location have been formed. The holding segments end on the residual material of the blank in the area of the frame or on the frame itself. The holding device is used especially as a workpiece for producing fully ceramic dental prostheses, particularly crowns or bridges.
    • 保持装置包括圆柱形或棱柱形多孔陶瓷坯料和用于夹紧在机床中的元件,用于通过去除材料来处理坯料,以便产生陶瓷工件。 在包围坯料的纵向中间轴线(A)的平面的区域中,窄框架通过粘合剂连接固定在坯料周边的至少一部分上,该坯料的周边保持无应力。 该框架仅覆盖坯件表面的一小部分,并且可以用夹紧适配器分离并保持在稳定的保持器中,使得其不能滑动。 整个组合固定在机床上,以防止扭转和滑动。 陶瓷工件在不预先确定前进方向的情况下连续地形成陶瓷坯料,直到形成仅能够根据数量和位置自由选择的保持段。 保持段在框架的区域中或框架本身上结束在坯料的残余材料上。 保持装置特别用作用于生产完全陶瓷牙科假体的工件,特别是冠或桥。
