Abstract: The invention relates to articulator devices for reproducing the movements of the mandible.The device according to the invention comprises means for sampling the movements of the mandible, composed of an upper plate, fixed to the patient's skull and a lower plate which is fixed to the mandible by way of a buccal fork. Six displacement sensors connect the two plates together, said sensors being joined to the said plates by way of swivel joints. The device further comprises an articulator composed of two plates on which are secured the casts of the upper and lower jaws of the patient, which plates are joined together by way of artificial muscles occupying the same position as that occupied by the sensors and each muscle comprising a servo-motor controlled by a sensor.The invention finds an application in the remote- or delayed-testing and adjusting of dental prostheses.
