有关齿残端石膏模型的牙齿残端冠部被紧固的制备是首先制备。 这种石膏模型的轮廓与触针（13）和所述轮廓数据扫描被输入到一个存储器（43）。 从冠部的轮廓和材料馈送的轮廓数据中的计算机（50）进行计算。 在齿残端的石膏模型，成型材料被施加，然后根据计算机（50）的工具（16）供给的轮廓，以处理该模制材料进行。

To prepare a to be fastened on a prepared tooth crown portion, a plaster model of the tooth stump is first produced. The contour of this plaster model is scanned with a probe pin (13) and the contour data is input to a memory (48). From the contour data, the contour of the crown portion and the addition of material is calculated in a computer (50). On the plaster model of the tooth stump a molding material is applied and then a tool (16) according to the computer (50) supplied contour is performed to process the molding material.
