摘要： 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.

摘要： A method for validating a preparation of at least one tooth in a prepared set of teeth for determining whether the prepared tooth is capable of accepting a dental restoration includes obtaining a virtual dental preparation guide configured for validating the preparation of the at least one tooth; obtaining a digital 3D representation of the prepared set of teeth; visualizing the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth; and validating from the visualization of the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth whether the prepared at least one tooth is shaped such that it can accept the dental restoration.

摘要： An intraoral 3D scanner includes a probe light source configured to generate a probe light such that the probe light is transmitted towards the dental situation; a camera including an array of sensor elements, the camera being arranged such that the probe light from the dental situation is transmitted to the array of sensor elements, wherein the camera is configured to create images of the dental situation from which a point cloud is generated, and a guiding system configured to guide relative movement of the intraoral 3D scanner towards the dental situation, wherein the camera is part of the guiding system, the camera is configured to record images from which a relative position of the intraoral 3D scanner and the dental situation is determined, such that based on the relative position, the guiding system is configured to provide a positioning signal in the form of a positioning color code.

摘要： A method for providing a guided relative movement of a first object and a second object includes obtaining the first object; obtaining the second object and a 3D model of the second object, and deriving from the 3D model a first preferred relative arrangement between the first and second objects; obtaining a pre-process plan describing a preferred path for the relative movement of the first and second objects towards the first preferred relative arrangement; performing a movement procedure that includes 3D scanning at least a region of said second object using the 3D scanner and determining a present relative arrangement of the first and second objects from a result of the 3D scanning; calculating information for correcting in real-time for deviation in the relative movement from the preferred path; and providing a relative movement of the first and second objects towards the first preferred relative arrangement.

摘要： Tools in a system for the design of customized three-dimensional models of dental restorations for subsequent manufacturing. Dental restorations such as implant abutments, copings, crowns, wax-ups, bridge frameworks. Moreover, a computer-readable medium for implementing such a system on a computer. A system for designing at least one dental restoration, said system including: a display, means for acquiring and displaying a three dimensional dental restoration model of the dental restoration, and means for displaying a plurality of control points, each of the control points corresponding to a respective location on the dental restoration model, and each of said control points enabling manual customization of the dental restoration model.
