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: A method for visualising a 3D dental restoration on a 2D image of the mouth of a patient includes obtaining a 3D dental model of at least a part of the patient's oral cavity, designing the 3D dental restoration, obtaining the 2D image of the mouth of the patient, estimating a virtual camera including at least one virtual camera property corresponding to at least one physical camera property of the physical camera used to obtain the 2D image, viewing the 3D dental restoration using the virtual camera, determining the visible area of the 3D dental restoration, which is not overlapped by surrounding anatomic features when viewed with the virtual camera, imaging the visible area of the 3D dental restoration with the 2D image. This advantageously provides an image which with high accuracy gives the dentist and the patient a visual presentation of the final result of a dental treatment.
