Abstract: A method for spatially resolved color determination, comprising the steps of projecting (S101) a first structured-light pattern having a first wavelength of light onto a dental object;
detecting (S102) a first spatially resolved optical parameter set based on the reflected or remitted first structured-light pattern; projecting (S103) a second structured-light pattern having a second wavelength of light onto the dental object; detecting (S104) a second spatially resolved optical parameter set based on the reflected or remitted second structured-light pattern; and calculating (S105) a third spatially resolved optical parameter set at a third wavelength of light based on the first and second spatially resolved optical parameter sets.

Abstract: A system for the color matching of dental restorations with teeth using a high degree of color correction followed by a display of maps showing the distribution of shades and values over the face of a tooth. The system can further utilize filters to output shade maps consisting of a predetermined number of shades and allow a technician to perform a virtual try in of the restoration in the patient's mouth.

Abstract: A dental imaging and illumination device. The device has an optical interface for emitting light from the device and for receiving light into the device. The device has a light source, a camera, a beam splitter and a color reference. The color reference and the light source are optically coupled via an optical path so that the light source can illuminate the color reference. This optical path bypasses the beam splitter. The device facilitates color measuring particularly in the field of dentistry.

Abstract: A method for optimizing initial discriminating information extracted from a two-dimensional image of the patient dental arches, referred to as “acquired image”, by a three-dimensional digital reference model of at least one portion of a patient arch, the method including the steps: C1. assessing quality of the initial discriminating information and quality threshold, filtering to keep only the initial discriminating information that has quality higher than the quality threshold, and defining “the discriminating information to be tested” as the initial discriminating information selected; C2. testing consistency between the discriminating information to be tested and reference model; C3. assessing test result and, in accordance with the assessment: adding discriminating information that was not kept to the discriminating information to be tested and/or deleting discriminating information from the discriminating information to be tested, and then returning to step C2. or; defining the optimal discriminating information as the discriminating information to be tested.

Abstract: A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.
