The method comprises a receiving of a three-dimensional digital model comprising a three-dimensional digital dental element, as well as repeatedly: a receiving of optical imaging data from an optical sensor device, a detecting of structural elements within the optical imaging data, a determining of a target position for the three-dimensional digital dental element using the reference points defined by the structural elements, and a controlling of an electronic display device for displaying an augmented reality view on the physical dental element augmented with the three-dimensional digital dental element.
