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.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 du visage du patient, l'obtention d'un modèle tridimensionnel de l'arcade d
