ABSTRACT:
This invention relates to a method and apparatus for functionally balancing the structure of a human mouth. With the method and apparatus of the invention, a pressure equalizing member is utilized wherein an occlusal surface of the posterior teeth of one jaw or denture are covered by a layer of a moldable substance that quickly cures to a hardened shape retaining form. The patient in whose mouth the moldable substance has been placed chews against the resistance offered by the pressure equilizing member so as to engrave the patient's chewing pattern on the opposed occlusal surface of the soft moldable layer. The pressure equalizing member is then removed from the patient's denture and a gap in the occlusal surface is filled with a moldable substance which after hardening overcomes prior art deficiencies to which the invention relates.
