ABSTRACT:
An apparatus for producing a desired balanced vertical jaw closure in a human mouth. First and second platform members, each capable of being respectively mounted in a fixed, known relation on the upper and lower jaws in spaced, vertically aligned juxtaposition are provided. A closed-air cell spacer member is connected between the platform members for providing an adjustable isometric pressure resistance against vertical closure of the jaws. A selectively movable piston action pin member is also connected between the platform members for selectively controlling the rest-close vertical relationship desired between the mounted platform members to protect against overclosure and damage to the ear canal and blood circulation to the cranium.
