The invention relates to a method for modeling the mandibular kinematics of a patient. Said method includes: acquiring at least one stereoscopic image of the face of the patient by means of a stereoscopic camera； building, from said stereoscopic image, a three-dimensional surface model of the face of the patient； identifying characteristic elements of the face of the patient on said stereoscopic image or on said three-dimensional surface model of the face of the patient； determining reference points, axes, and planes for the face of the patient on said stereoscopic image and on said three-dimensional surface model of the face of the patient, respectively, on the basis of said characteristic elements； obtaining a three-dimensional model of the maxillary dental arch and a three-dimensional model of the mandibular dental arch of the patient； registering the three-dimensional models of the dental arches relative to the reference planes of the three-dimensional surface model of the patient； recording the mandibular kinematics of the patient； and applying said recorded mandibular kinematics to the three-dimensional models of the registered dental arches such as to animate said three-dimensional models.
