Abstract: Disclosed are a scanner system and a method for recording surface geometry and surface color of an object where both surface geometry information and surface color information for a block of the image sensor pixels at least partly from one 2D image recorded by the color image sensor. A particular application is within dentistry, particularly for intraoral scanning.

Abstract: Disclosed is a method for manufacturing a denture including a denture base and at least two artificial teeth arranged in the denture base, wherein the method includes the steps of obtaining the denture base; manufacturing the at least two artificial teeth with a common placement support connected to the at least two artificial teeth for keeping the at least two artificial teeth in a desired relative arrangement, arranging the at least two artificial teeth on the denture base with the common placement support connected to the at least artificial teeth, attaching the at least two artificial teeth on the denture base, and removing the common placement support. This further ensures proper placement of the artificial teeth in the denture base of a denture.

Abstract: A method for improving the accuracy of a digital medical model of a part of a patient, the method includes obtaining a set of at least 2 medical images of the patient, where an element comprising a predefined geometry and/or predefined information was attached to the patient during the recording of the medical images; obtaining at least 2 tracking images taken with at least one camera having a known positional relationship relative to the medical imaging device, said tracking images depicting at least part of the element; determining any movement of the element between acquisition of the at least 2 tracking images; and generating the digital medical model from the acquired medical images, wherein the determined movement of the element is used to compensate for any movement of the patient between the acquisition of the medical images.

Abstract: A method, a system and a user interface for generating a digital design for use in the manufacture of a molding-shell for a patient's teeth, where the molding-shell and the teeth together enclose a volume for forming a dental restoration, include obtaining a digital 3D representation of the patient's teeth, the digital 3D representation including a tooth part relating to one or more teeth for which the dental restoration is formed; obtaining a set of one or more digital teeth anatomies; arranging the set of digital teeth anatomies and the digital 3D representation according to a preferred relative arrangement; and generating the digital design where a first portion of the digital design is derived from the digital teeth anatomies and a second portion of the digital design is derived from the tooth part of the digital 3D representation.

Abstract: Disclosed is a 3D scanner for recording the 3D topography of an object, the 3D scanner including: a projector unit configured for projecting a structured beam of probe light onto the object; an imaging unit arranged to acquire 2D images of the object when the object is illuminated by the structured probe light beam; and an actuator unit arranged to control the position of the structured probe light beam at the object by rotating a movable portion of the projector unit around a pivoting axis, the actuator unit including a rotation motor including or arranged to drive a wheel, where the surface of the wheel operatively coupled to the movable portion of the projector unit has a radial distance from the axis of the rotation motor which changes with the rotation.

Abstract: Disclosed is a method for digitally designing a dental restoration, wherein a 3D representation of at least a part of the upper or lower jaw is obtained. The 3D representation represents at least a target site for placing the final restoration and at least one antagonist tooth opposing the target site. Furthermore a digital anatomy design of the restoration is provided. The digital anatomy is based at least on a dynamic occlusion and a relative offset of the planned restoration position. Accordingly, a restoration may be designed that does not interrupt the natural occlusion.

Abstract: A method that generally relates to comparing a current dental setup with a series of preset dental setups. More particularly a method where this comparison is used to determine which aligner should be used from a series of dental aligners for proceeding with an orthodontic treatment. Each aligner in the series of previously manufactured aligners is provided for moving the at least one tooth in the patient's teeth from one dental setup to a subsequent dental setup.

Abstract: Presented is an optical coherence tomography system and method to increase imaging depth of optical coherence tomography (OCT) by selective amplification. In a swept-source OCT system with periodically linear wavenumber-vs-time characteristic, the signal in principle is summation of various sinusoidal signals with different frequencies. Each frequency component of the recorded signal carries reflectivity information for a certain depth of the analyzed object. At greater depth inside the analyzed object, the reflectivity information is generally weak due absorption and scattering. An analog or digital electronic circuit selectively filters and amplifies frequencies above some threshold, possibly up to another threshold. In this way, even small signals for relatively larger depths become detectable.

Abstract: Disclosed is an optical coherence tomography scanner and a method for recording sub-surface scans of an object, wherein a position encoder is arranged in the path of the probing beam of an interferometric system. The encoder pattern is detected in a sequence of A scans at generated for different probing beam positions on the scanned object, the probing beam position and/or inclination for at least one A scan of said sequence of A scans is deducing based on the detected encoder pattern, and the sub-surface scan of the object is generated based on the sequence of A scans taking into account the deduced probing beam position and/or inclination.
