Abstract: A computer product for generating a digital 3D model for use in a dental component based on a digital 3D model of the dental component showing a shape of the teeth and a digital 3D representation of a pre-prepared set of teeth showing the region for which the dental component is intended, the product causing a system to generate a digital 3D combined model representing a target dental situation when the dental component is arranged at the teeth, where the instructions are configured for digitally replacing one or more teeth of the digital 3D representation of the pre-prepared set of teeth with the digital 3D model of the dental component by digitally removing the one or more teeth of the digital 3D representation of the pre-prepared set of teeth and adding the digital 3D model of the dental component to the digital 3D representation of the pre-prepared set of teeth.

Abstract: A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.

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.

Abstract: Disclosed is surface guided cropping in volume rendering of 3D volumetric data from intervening anatomical structures in the patient's body. A digital 3D representation expressing the topography of a first anatomical structure is used to define a clipping surface or a bounding volume which then is used in the volume rendering to exclude data from an intervening structure when generating a 2D projection of the first anatomical structure.
