According to an embodiment, a computer-implemented method of generating a virtual model of a set of teeth for manufacturing a physical model of the set of teeth is disclosed. The model comprises one or more teeth preparations and the method includes generating a virtual model of the set of teeth, where the virtual model is based on a virtual representation of the set of teeth； providing that each of the teeth preparation is configured to be arranged as a removable component in the model, where each removable component is adapted to fit into a corresponding cavity in a gingival part of the model； providing means for supporting and positioning each of the removable components in its corresponding cavity in the model； and configuring the means for supporting and positioning such that an area of contact between each removable component and its corresponding cavity is smaller than an area in which there is no contact between the removable component and the cavity.
