Abstract: The present disclosure relates to an intraoral scanning device including a light source configured for emitting light; a beam splitter configured for outputting linearly polarized light of a predefined orientation, wherein the beam splitter is arranged such that light from the light source is transmitted through the beam splitter; an image sensor configured for acquiring one or more images; and a light absorbing unit for minimizing stray light on the image sensor, said light absorbing unit arranged on a surface of the beam splitter. The present disclosure further relates to an optical system for an intraoral scanning device, said optical system configured for minimizing stray light in the system.

Abstract: The present disclosure provides a computer-implemented method for correlating at least one infrared 2D-image to a 3D-representation of at least a part of a tooth displayed in a graphical user-interface, of a hand-held scanning device, on a screen, including the steps of: obtaining a first set of 2D-images of the at least part of the tooth; forming a 3D-representation of the at least a part of the tooth from the first set of 2D-images; displaying, in the graphical user-interface, the 3D-representation; obtaining a second set of 2D-images, wherein the second set of 2D images are infrared 2D-images acquired within the at least part of the tooth; displaying, in the user-interface, at least one of the 2D-images from the second set of 2D-images; displaying, in the user-interface, a manipulator configured to change between 2D-images in the second set of 2D-images.

Abstract: According to an embodiment, a method for generating a digital three-dimensional model representing development in dental condition for a tooth is disclosed. The method includes obtaining, at different timepoints, a first digital 3D model of a patient's set of teeth including first texture data and a second digital 3D model of the patient's set of teeth including second texture data. The first digital 3D model including the first texture data and second digital 3D model including the second texture data are placed in a common texture space by uniformizing texture. Lastly, the digital three-dimensional model representing development in dental condition is generated based on a comparison of the first texture data and the second texture data of corresponding regions in the first digital 3D model and the second digital 3D model placed in the common texture space.
