1. Method for incorporating photographic facial images and/or films of a person into the planning of odontological and/or cosmetic dental treatments and/or the preparation of restorations for said person, comprising:
producing the photographic facial images and/or films using a camera function of a smart device, a user being guided through the production of the photographic facial images and/or films with the aid of an application for the smart device by:
providing guidance on a positioning of the smart device for taking a first photographic facial image and/or film in a first perspective using a template, wherein guidance through the production of the photographic facial images and/or films specifies the recording of the person in different positions by:
providing a central line on an interface of the smart device, the central line comprising a plurality of visualized position points:
wherein the smart device is successively moved to corresponding to the visualized position points and the photographic facial images and/or films are generated,
wherein additional photographic facial images and/or films are generated for positions above and below the central line;
generating the first photographic facial image and/or film;
based on feedback, changing the template to provide guidance on the positioning of the smart device for taking a second or other photographic facial image and/or film in a different perspective;
generating the second or other photographic facial image and/or film:
performing, in real time, a suitability check about a suitability of the photographic facial images and/or films for digital processing, the suitability check including at least a check for an image detail, and a check for a lighting condition;
responsive to determining that at least one of the photographic facial images and/or films fails the suitability check, providing additional guidance for repeating and improving the at least one of the photographic facial images and/or films;
generating a three-dimensional model by converting the photographic facial Images and/or films into the three-dimensional model;
responsive to generating the three-dimensional model, digitally designing a restoration and/or treatment plan using the three-dimensional model, a visualization of the photographic facial images and/or films being used in the digitally designing;
wherein the method further comprises providing guidance for recording a smile and for using a cheek retractor; and
generating corresponding photographic facial images and/or films which are additionally used in generating the three-dimensional model.
