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 numerical models (MD, MX) of the mandibular and maxillary arches of the patient； - providing a recording of the mandibular motion of the patient, said recording comprising a plurality of relative positions of the mandible of the patient with respect to the maxilla； - selecting, from said positions, a reference position (X) of the mandible with respect to the maxilla of the patient； - determining a target position (Y) for the mandible with respect to the maxilla, said target position defining a corrected intermaxillary relationship for the patient； - determining a rigid transformation between the reference position (X) and the target position (Y)； - applying said rigid transformation (i) to the recording of the mandibular motion of the patient in order to animate the three-dimensional numerical models of the mandibular and maxillary arches, or (ii) to the three-dimensional numerical model of the mandible, the delivered recording of the mandibular motion being applied to the three-dimensional numerical models of the mandible and of the maxilla in order 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) de la mandibule par rapport au maxillaire du patient, -la détermination d'une position cible (Y) de la mandibule par rapport au maxillaire, ladite position cible défi
