Abstract: The method (100) for estimating and viewing a result of a dental treatment plan comprises: a step (105) of reconstructing, in a virtual space in three-dimensions, the shape of the face of a patient, a step (125) of reconstructing, in the virtual space in three-dimensions, the dentition of a patient, a step (142) of assembling the reconstructed shape of the face and the reconstructed dentition in the virtual space in three-dimensions, a step (145) of determining at least one dental treatment plan depending on the modeled dentition and face, a step (150) of selecting a treatment plan from the set of determined treatment plans, a step (155) of computing an image of how the face of the patient will look after the dental treatment depending on an image of the face of the patient and on the selected treatment plan and a step (160) of displaying the computed image.

Abstract: The invention relates to a method for a user to control a device. According to the invention, the method comprises the following steps:—identification of a device located in a viewing direction of the user (100) by means of analysis of at least one image obtained by an image sensor (111) and containing at least part of the user's (100) face; determination of an oral instruction; transmission of a command associated with the determined oral instruction to the device identified. The invention also relates to a control device (110) in which such a method can be carried out, as well as a system (110, 121, 122) and a motor vehicle (130) comprising such a device (110).
