Title (EN) VIRTUAL MODEL OF ARTICULATION FROM INTRA-ORAL SCANS
(FR) MODÈLE VIRTUEL D’ARTICULATION À PARTIR DE SCANS INTRABUCCAUX
Abstract:
(EN) A method for determining virtual articulation from dental scans. The method includes receiving digital 3D models of a person's maxillary and mandibular arches, and digital 3D models of a plurality of different bite poses of the arches. The digital 3D models of the maxillary and mandibular arches are registered with the bite poses to generate transforms defining spatial relationships between the arches for the bite poses. Based upon the digital 3D models and transforms, the method computes a pure rotation axis representation for each bite pose of the mandibular arch with respect to the maxillary arch. The virtual articulation can be used in making restorations or for diagnostic purposes.
(FR) La présente invention concerne un procédé de détermination d’une articulation virtuelle à partir de scans dentaires. Le procédé comprend la réception de modèles 3D numériques des arcades maxillaire et mandibulaire d’une personne, et des modèles 3D numériques d’une pluralité de positions de morsure différentes des arcades. Les modèles 3D numériques des arcades maxillaire et mandibulaire sont enregistrés avec les positions de morsure pour générer des transformées définissant des relations spatiales entre les arcades pour les positions de morsure. Sur la base des modèles 3D numériques et des transformées, le procédé calcule une représentation d’axe de rotation pure pour chaque position de morsure de l’arcade mandibulaire par rapport à l’arcade maxillaire. L’articulation virtuelle peut être utilisée dans la réalisation de restaurations ou à des fins de diagnostic.
