ABSTRACT:
The dental articulator to test the "bite" of cast upper and lower jaw dentures in which a rearward horizontally oriented pivot of the upper jaw denture is mounted for pivotal traverses in an open arcuate-shaped cooperating support of the lower jaw denture and this simple articulating construction and vertical adjustment between the two dentures is due to a large extent to the use of rubber bands to hold the referenced pivots on their arcuate supports.
