Abstract: A method for colourising a three-dimensional point cloud including surveying a point cloud with a surveying instrument. Each point of the point cloud may be characterised by coordinates within an instrument coordinate system having an instrument center. The method may include capturing a first image of the setting with a first camera. Each pixel value of the first image is assigned coordinates within a first camera coordinate system having a first projection center as origin and a first parallax shift relative to the instrument center. The method may include transforming the point cloud from the instrument coordinate system into the first camera coordinate system, resulting in a first transformed point cloud, detecting one or more uncovered points within the first transformed point cloud which are openly visible from the first projection center, and for each uncovered point, assigning a pixel value having corresponding coordinates in the first camera coordinate system.

Abstract: An anchor for securing a tooth replacement includes an anchoring part secured to an implant or jaw, having a recess, and a pivoting part to which the tooth replacement can be secured and which contains a pin. The pivoting part is pivotable with respect to the anchoring part when the pin is received in the recess. The anchor is configured to permit application of a hardenable substance in the recess of the anchoring part so as to fix the pivoting part in a defined position of pivoting.

Abstract: The anchor for securing a tooth replacement comprises an anchoring part (1) which can be secured to an implant or jaw and which has a recess (2), and a pivoting part (10) to which the tooth replacement can be secured and which contains a pin (11). The pivoting part is pivotable with respect to the anchoring part when the pin is received in the recess. The anchor comprises means (15, 19) for applying a hardenable substance in the recess (2) of the anchoring part (1), in order to fix the pivoting part in a defined position of pivoting.
