Abstract: A method and device for radiographing the human jaw joints for providing a clear image of one of the joints on one dental film and for providing a clear image of the other joint on a separate second dental film, comprising a frame equipped for mounting the respective films on either side of the patient's head, with the respective film holders of the frame and an X-ray positioning target for each such holder being arranged in sets oriented to be coordinated with the patient's Ala-tragal plane, in which the film holder of each set is disposed adjacent the jaw joint to be radiographed and the target therefor is disposed on the other side of the patient's head on an X-ray axis that is to pass through the joint the particular film is to bear, which axis is oblique to a straight line connecting the jaw joints to be radiographed.
