    • The invention relates to the processing of data regarding the three dimensional shape of a dental prosthesis, which has two prosthesis sections and a connector section, said connector section being connected to the two prosthesis sections and less stable than the two prosthesis sections, comprising the steps that:—a stability parameter and a stability criterion are determined for the connector section;—for the stability parameter, the actual value is calculated from the data;—it is checked for the connector section as to whether the actual value fulfills the stability criterion, and if not, that a warning signal is generated, wherein the determination of the stability criterion is dependent on at least one of the following prosthesis attributes:—the configuration of the prosthesis;—the position of the prosthesis inside the mouth;—the material and/or the cross-sectional profile of the connector section;—the type of the prosthesis sections adjoining the connector section.
    • 本发明涉及关于具有两个假体部分和连接器部分的牙科假体的三维形状的数据的处理,所述连接器部分连接到两个假体部分并且比两个假体部分更不稳定,包括步骤 确定: - 连接器部分确定稳定性参数和稳定性标准; - 对于稳定性参数,根据数据计算实际值; - 连接器部分检查实际值是否符合稳定性标准 并且如果不是,则产生警告信号,其中稳定性标准的确定取决于以下假体属性中的至少一个: - 假体的构造; - 假体在口内的位置; - 材料和/或连接器部分的横截面轮廓; - 邻接连接器部分的假体部分的类型。

    • A one-hand operated dispenser for metering dental compositions comprises a casing for receiving the dental composition between a forward dispensing end and a plunger which is movably mounted within the casing. The plunger is moved forwardly by means of a threaded spindle which engages with a nut disposed on the rear casing end so as to be secured against rotation and axial movement. The thus formed assembly may be inserted into two bifurcated brackets of a generally U-shaped receptacle forming part of a manipulating member. The spindle is guided in the one bracket so as to be axially movable and non-rotatable, while the casing with the nut is mounted in the other bracket so as to be non-displaceable but rotatable. When the manipulating member is gripped, the casing may be turned between thumb and index finger such that the spindle is pushed forwards, whereby the dental composition exits from the dispensing opening.
    • 用于计量牙科用组合物的单手操作分配器包括用于在前分配端和可移动地安装在壳体内的柱塞之间接收牙科组合物的壳体。 柱塞通过螺纹轴向前移动,螺纹心轴与设置在后壳体端部上的螺母接合,以被固定抵抗旋转和轴向运动。 如此形成的组件可以插入形成操纵构件的一部分的大致U形的容器的两个分叉支架中。 主轴在一个支架中被引导成可轴向移动和不可转动,而具有螺母的壳体安装在另一个支架中,以便不可移动但是可旋转。 当操作构件被夹紧时,壳体可以在拇指和食指之间转动,使得心轴被向前推动,由此牙科组合物从分配开口离开。
