Abstract: A method of performing a three-dimensional (3D) scan of an object includes applying an optical contrast powder to the object and illuminating the object with light. First and second two-dimensional (2D) color image data corresponding to the object is generated. First and second 2D monochrome image data corresponding to the object is generated using the first and second 2D color image data. 3D data corresponding to the object is generated using the first and second monochrome 2D image data. Color 3D image data corresponding to the object is generated by adding color information to the 3D data. The color 3D image data is displayed.

Abstract: The invention relates to a measuring system for measuring an implant-implant situation for planning an implant-supported tooth replacement part supported on at least two implants, comprising a scanning template and the at least two set implants. The scanning template has cut-outs for the individual implants, wherein first markings are arranged on surface regions around the cut-outs.

Abstract: The method for optical three-dimensional surveying using an intraoral camera (2), wherein the intraoral camera (2) provides that a 3D image is created from at least one of the 2D recorded images or from at least one of the sequences, and wherein a plurality of all the 2D recorded images and/or sequences created in a first operating mode (M1) are used to create at least one overall 3D image. In addition, the method provides that a selection is made between the first operating mode (M1) and a second operating mode (M2), wherein a plurality of all 2D recorded images and/or sequences created during an interval of time (T) are used in the second operating mode (M2) to create at least one 3D image immediately before and/or after a triggering command (A).
