ABSTRACT:
A device for recording images of a patient's jaw includes a holder carrying a radiation window disposed externally of the patient's mouth and mounting a carrier disposed within a patient's mouth. A biting element is connected to the carrier and projects toward the window and the carrier provides a surface facing the window and against which a radiation sensitive plate is located. Location and positioning of the plate against the surface is effected by a cap which fits over the carrier. The cap has rounded corners and is formed of flexible material to protect the patient's mouth from injury. The carrier is formed of a first part which attaches to the holder and a second part which is adjustable thereon parallel to the window and the biting element is adjustable laterally on the first part to allow further adjustment of the plate within the patient's mouth. The biting element is provided with a recess for curable material so that the patient's teeth may make a permanent impression to allow the same biting element to be used in a subsequent image making process while assuring the original location of the patient's teeth with respect thereto.
