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).

Abstract: The present disclosure relates to a computer-implemented method for designing a dental prosthesis. A first step of the method may be to obtain a digital 3D representation of a surface, the surface including at least a part of a preparation surface adapted to receive the dental prosthesis, wherein the preparation surface includes a visible part and a hidden part. A second step of the method may be to determine at least one part of a surface of the dental prosthesis using a statistical design model, wherein the at least one part is determined independent of any knowledge or estimate of the hidden part of the preparation surface. A final step of the method may be to design the dental prosthesis wherein the surface of the dental prosthesis includes the at least one part.
