The invention relates to a method for animating models of the mandibular and maxillary arches of a patient in a corrected intermaxillary relationship, comprising: providing three-dimensional digital models (MD, MX) of the mandibular and maxillary arches of the patient, providing a record of the patient's mandibular kinematics, said record comprising a plurality of relative positions of the patient's mandible relative to the maxilla, the selection, from among said positions, of an initial reference position (X) of the mandible relative to to the patient's maxilla, and a target position (Y) of the mandible relative to the maxilla, said target position defining a corrected intermaxillary relationship of the patient, determining a rigid transformation between the initial reference position (X) and the target position (Y), the application of said rigid transformation (i) to the recording of the patient's mandibular kinematics for year imer the three-dimensional digital models of the mandibular and maxillary arches, or (ii) the three-dimensional digital model of the mandible, the recording of the mandibular kinematics provided being applied to the three-dimensional digital models of the mandible and the maxilla to animate said models. L’invention concerne un procédé d’animation de modèles des arcades mandibulaire et maxillaire d’un patient dans une relation intermaxillaire corrigée, comprenant : la fourniture de modèles numériques tridimensionnels (MD, MX) des arcades mandibulaire et maxillaire du patient, la fourniture d’un enregistrement de la cinématique mandibulaire du patient, ledit enregistrement comprenant une pluralité de positions relatives de la mandibule du patient par rapport au maxillaire, la sélection, parmi lesdites positions, d’une position de référence (X) initiale de la mandibule par rapport au maxillaire du patient, et d’une position cible (Y) de la mandibule par rapport au maxi
