借助于CAM制造的牙齿模型中的可去除部件的支座
摘要：
公开了一种生成牙齿组的虚拟模型以用于制造所述牙齿组的实体模型的计算机执行方法，所述方法包括：提供所述牙齿组(402)的虚拟模型，所述模型包括齿龈部分(401)和构造成所述模型中的可去除部件(405)的一部分的牙齿；生成所述齿龈部分中的腔(407)，所述腔包括腔壁，所述可去除部件装配在所述腔中使得限定所述可去除部件(405)和所述腔(407)的壁之间的接口，其中所述可去除部件(405)和所述腔(407)被构造成提供所述接口处的间隙；以及提供用于将所述可去除部件(405)支撑和定位在所述腔(407)中的装置(409)，其中所述用于支撑和定位的装置在所述可去除部件和所述腔壁中的一个上产生使得所述用于支撑和定位的装置(409)延伸横越所述可去除部件(405)和所述腔壁之间的所述间隙；-其中所述接口处的所述可去除部件(405)和所述腔壁之间的接触面积由所述用于支撑和定位的装置(409)和所述可去除部件(405)和所述腔壁中的另一个的邻接表面的形状控制。
摘要（英）：

Disclosed is a computer-implemented method of generating a virtual model of a set of teeth for manufacturing a physical model of the set of teeth, the method comprising: - providing a virtual model of the set of teeth (402), the model comprising a gingival part (401) and a tooth configured to be part of a removable component (405) in the model; - generating a cavity (407) in said gingival part, said cavity comprising a cavity wall, into which cavity said removable component fits such that an interface between the removable component (405) and the wall of the cavity (407) is defined, where the removable component (405) and the cavity (407) are configured to provide a gap at said interface; and - providing means (409) for supporting and positioning the removable component (405) in the cavity (407), where the means for supporting and postitioning are generated on one of said removable component and said cavity wall such that the means (409) for supporting and positioning extends across said gap between said removable component (405) and said cavity wall; - wherein the area of contact between the removable component (405) and the cavity wall at said interface is controlled by the shape of the adjoining surfaces of the means (409) for supporting and positioning and the other of the removable component (405) and the cavity wall.
