The invention pertains to a method for exporting design data of a virtual 3D dental design model (12) from an AR application, the AR application being adapted to visualize the dental design model with a preliminary pose and scale (13) in an image (11) of a face comprising a mouth region with a dental situation, the method comprising providing a 3D scan model (14) of the dental situation, aligning the dental situation of the scan model and the dental situation in the image to obtain a pose of the scan model, and calculating, based on the preliminary pose and scale and the pose of the scan model, at least one transformation to bring the design model and the scan model into a common coordinate system. The invention further pertains to a method for visualizing a 3D dental design model in an AR application wherein the method comprises providing the dental design model, a 3D scan model of a dental situation and an image of a face comprising a mouth region with the dental situation, determining a pose for the dental design model based on the image and on a relative transformation from the scan model to the dental design model, and rendering the dental design model in the image with the determined pose. |
