Abstract: The present disclosure relates to a computer-implemented method for providing feedback during scanning of a dental object, comprising the steps of obtaining scan data of the dental object; generating a digital three-dimensional (3D) representation of the dental object based on the scan data; obtaining new scan data of the dental object; generating an updated digital 3D representation by adding the new scan data to the digital 3D representation; determining added information to the digital 3D representation by comparing the new scan data to at least one of the digital 3D representation(s) and/or by comparing the updated digital 3D representation to the digital 3D representation(s); and providing a feedback signal; wherein the feedback signal correlates with the added information and/or a determined overlap. The present disclosure further relates to a 3D scanner system and a handheld intraoral scanning device, configured for providing the feedback signal such as by executing the computer-implemented method.

Abstract: An intraoral scanner system (100) includes a handheld intraoral scanner (101) configured to obtain light information reflected from a dental object (108) inside an oral cavity through a field-of-view (105) of the handheld intraoral scanner (101), one or more processors configured to process the light information and to generate a digital 3D model (103) of the dental object (108) based on the processed light information, and a graphical user interface (102) configured to display the digital 3D model (103). The one or more processors are configured to display in real-time and on the graphical user interface (102) a field-of-view frame (104) representing a position of the field-of-view (105) of the handheld intraoral scanner (101) and generate a correction feedback signal that corresponds to the field-of-view frame (104), and wherein the correction feedback signal includes a suggested correction of the position of the field-of-view (105) of the handheld intraoral scanner (101).
