Visual aid device

Abstract

Abstract A DEVICE IS DESCRIBED WHICH PERMITS THE VISUAL DEMONSTRATION OF ANATOMICAL MOVEMENTS OF THE HUMAN MANDIBLE AND THE RELATIONSHIP OF SUCH MOVEMENTS TO THE HUMAN TEETH. THE DEVICE COMPRISES A PAIR OF PLATES, ONE OF WHICH BEARS A VIEW OF THE MANDIBULAR TEETH AND THE OTHER OF WHICH BEARS A VIEW OF THE MAXILLARY TEETH TAKEN ALONG HORIZONTAL, SAGITIAL OR CORONAL PLANES. THE LOCATION OF WORKING AND FUNCTIONAL CUSPS ARE IDENTIFIED ON THE VIEWS AND, PREFERABLY, AT LEAST THE UPPER PLATE IS TRANSPARENT SO THAT THE RELATIVE MOVEMENTS OF THESE CUSPS CAN BE DIRECTLY OBSERVED. THE UPPER PLATE CAN ALSO BE PERFORATED AT THE LOCATIONS OF THE FUNCTIONAL CUSPS SO THAT A STYLUS CAN BE INSERTED TO TRACE THE PATHWAYS OF THE CUSPS ON THE VIEW OF THE LOWER PLATE. THE PLATES ARE INTERCONNECTED BY MEANS THAT PERMIT TWO DIMENSIONAL SIMULATION OF THE ANATOMICAL MOVEMENTS AND SUCH MEANS CAN BE PLURALITY OF GROOVES AT THE RIGHT AND LEFT SIDES OF ONE PLATE WITH AN APERTURE IN THE OTHER PLATE VERTICALLY ALIGNED OVER EACH GROOVE WITH A PAIR OF PINS, ONE AT EACH SIDE OF THE PLATES, INSERTED BETWEEN AN APERTURE AND MATING GROOVE TO LINK THE PLATES TOGETHER. ALTERNATIVE MEANS COMPRISES A DENTAL ARTICULATOR THAT PERMITS THREE DIMENSIONAL SIMULATION OF THE ANATOMICAL MOVEMENTS.
