ABSTRACT:
A dental recording apparatus for recording the movements of the jaw joints in relation to the skull includes (A) an adjustable upper recording bow which is secured on the bridge of the nose, the top of the skull and the sides of the head and which has a nose bridge support, vertical frame, rubber strap and positioning units or measuring/recording plates, and (B) a lower recording bow. The apparatus permits an exact positioning of the apparatus on the head of the patient, both in terms of an exact positioning of the upper recording bow and also of the lower recording bow. The positioning devices located on the upper recording bow has inwardly arranged earplugs, and outwardly arranged pins which are used for the coupling of the side arms of the lower recording bow, in order to be able to couple the side arms of the lower recording bow exactly at right angles, as a result of which parallelization of the lower recording bow to the upper recording bow and to the pivot axis of the jaw joints is necessarily achieved.
