The invention relates to a method for modeling the mandibular kinematics of a patient, comprising: - the acquisition of at least one stereoscopic image of the patient's face by means of a stereoscopic camera, - the construction, from said stereoscopic image, of a three-dimensional surface model of the patient's face, - the identification of characteristic elements of the patient's face on said stereoscopic image or on said three-dimensional surface model of the patient's face, - from said characteristic elements, the determination of on said stereoscopic image, respectively said three-dimensional surface model of the patient's face, points, axes and reference planes of the patient's face, - obtaining a three-dimensional model of the maxillary dental arch and a three-dimensional model of the mandibular dental arch of the patient, - the registration of the three-dimensional models of the dental arches with respect to to the reference planes of the three-dimensional surface model of the patient, - the recording of the mandibular kinematics of the patient, - the application of said registered mandibular kinematics to the three-dimensional models of the recalibrated dental arches, to animate said three-dimensional models. L'invention concerne un procédé de modélisation de la cinématique mandibulaire d'un patient, comprenant : - l'acquisition d'au moins une image stéréoscopique du visage du patient au moyen d'une caméra stéréoscopique, - la construction, à partir de ladite image stéréoscopique, d'un modèle surfacique tridimensionnel du visage du patient, - l'identification d'éléments caractéristiques du visage du patient sur ladite image stéréoscopique ou sur ledit modèle surfacique tridimensionnel du visage du patient, - à partir desdits éléments caractéristiques, la détermination, sur ladite image stéréoscopique, respectivement ledit modèle surfacique tridimensionnel du visage du patient, de points, axes et plans de référence
