Abstract: Disclosed is a method for determining the geometrical relationship between a patient's dental structure and a reference feature on the head of the patient, the method including obtaining a first digital representation of a facebow including a fiducial marker, an adjustable pin member attached to the facebow and an attachment section of the facebow for placing the facebow in relation to the reference feature, the attachment section having a geometrical relationship with the fiducial marker; obtaining a second digital representation comprising a part of the patient's dental structure, a part of the pin member, and part of the facebow including the fiducial marker; obtaining information about the placement of the attachment section relative to the reference feature; and determining the geometrical relationship between the patient's dental structure and the reference feature based on the first and second digital representations and the placement of the attachment section.

Abstract: 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 one or more kinds of spacer elements, where the method includes obtaining a virtual 3D dental model, providing a virtual dental articulator, 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, 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, equals the articulator height.

Abstract: Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.

Abstract: A method of reducing the x-ray dose of a patient in an x-ray system includes defining a region of interest of the patient, obtaining at least two tracking images of a tracking element taken with at least one camera having a known positional relationship relative to an x-ray source and/or sensor, determining any movement of the tracking element between the acquisition of at least two tracking images, adjusting the collimator of the x-ray source to compensate for any movement of the tracking element between the acquisition of the at least two tracking images, providing that the field of exposure of the x-ray source is confined to the region of interest and obtaining at least one x-ray image of the region of interest after the adjustment of the collimator.

Abstract: Disclosed is a computer-implemented method of using a dynamic virtual articulator for simulating occlusion of teeth, when performing computer-aided designing of one or more dental restorations for a patient, where the method includes the steps of: providing the virtual articulator including a virtual three-dimensional model of the upper jaw and a virtual three-dimensional model of the lower jaw resembling the upper jaw and lower jaw, respectively, of the patient's mouth; providing movement of the virtual upper jaw and the virtual lower jaw relative to each other for simulating dynamic occlusion, whereby collisions between teeth in the virtual upper and virtual lower jaw occur; wherein the method further includes: providing that the teeth in the virtual upper jaw and virtual lower jaw are blocked from penetrating each other's virtual surfaces in the collisions.
