Abstract
(EN)
Methods are provided to record and utilize jaw motion data using low-angle photogrammetric techniques. A method is described based on using an extraoral imaging apparatus to capture images of texture placed on tooth or soft tissue surfaces. Upper and lower textural surface regions of the oral cavity are imaged simultaneously, and their surfaces derived as a function of time to produce 4d data. The clinically derived surface data may be directly registered to the 3d anatomy of an individual, providing the ability to animate the relative motion of the mandible. An imaging apparatus suitable for capture of low-angle image groups is disclosed.

L'invention porte sur des procédés d'enregistrement et d'utilisation de données de mouvement de mâchoire à l'aide de techniques photogrammétriques à petit angle. Un procédé est décrit, celui-ci étant fondé sur l'utilisation d'un appareil d'imagerie extra-buccale pour capturer des images de texture placée sur des surfaces de dent ou de tissu mou. Des régions de surface texturale supérieure et inférieure de la cavité orale sont soumises à une imagerie simultanément, et leurs surfaces sont calculées en fonction du temps afin de produire des données en 4D. Les données de surface cliniquement obtenues peuvent être directement superposées à l'anatomie en 3D d'un individu, offrant la capacité d'animer le mouvement relatif de la mandibule. Un appareil d'imagerie approprié pour capturer des groupes d'images à petit angle est également décrit.
