The invention is directed to a method for creating a teeth model comprising: providing a virtual three dimensional (3D) representation of a patient's dentition that comprises a region of the teeth that includes a tooth stump on which a crown is to be fitted or a region on to which a bridge is to be fitted, wherein the virtual three dimensional (3D) representation comprises information for the upper and lower jaw and their spatial relationship in occlusion； and based on information from said virtual 3D representation, generating a 3D model of a crown to be fitted on said tooth stump or of a bridge to be fitted on said region.
