Abstract: Disclosed is a method for virtually designing the attachment of a manufactured dental model of a patient's set of teeth in a physical dental articulator by means of one or more kinds of spacer elements, where the method comprises: obtaining a virtual 3D dental model of the patient's set of teeth, where the virtual 3D dental model is provided by means of 3D scanning; providing a virtual dental articulator type corresponding to a physical dental articulator, where the dental articulator comprises an upper arm and a lower arm and has a known articulator height, which is the distance between the upper arm and the lower arm in the static position of the dental articulator; providing a minimum height of the dental model, where the height of the dental model is the height of an upper part and the height of a lower part of the dental model; providing one or more kinds of virtual spacer elements with predetermined heights, where each kind of virtual spacer element corresponds to a physical spacer element; determining a manufacture height of the dental model and determining the number of each of the kinds of spacer elements to be used for the attachment of the manufactured dental model in the physical articulator, such that the manufacture height of the dental model and the total effective spacer element height, which is the added height of the determined spacer elements, equal the articulator height, and where the manufacture height of the dental model is not less than the minimum height of the dental model.
