A system for scanning anatomical structures and for visualizing the scanning result, wherein the system includes an intraoral scanner, which intraorally captures an image of the anatomical structures, an extraoral detection unit, which detects a spatial position of the intraoral scanner relative to an observer or a person conducting the scan, and a computing unit, which, during the scanning procedure, connects the scanner with a screen and the detection unit and generates a scanning result based on the intraorally captured image of the anatomical structures and the detected spatial position of the intraoral scanner relative to the observer, and which, during pauses in the scanning procedure, estimates the position, orientation and scaling of the anatomical structures and, as a scanning result, generates an image of the anatomical structures corresponding to the estimation, and wherein the screen displays the scanning result generated by the computing unit.
