ABSTRACT:
Method and apparatus for obtaining and maintaining optimum performance of inter-jaw biting musculature for seating and cementing dental crowns and bridges, such method including utilizing the biting musculature only within the limits of relaxed muscle-fiber length, using said apparatus as physiologically-appropriate contact and pressure reference for sensory-motor innervation feed-back from muscles and dental structures to determine and control muscle performance and using said apparatus as means for controlling inter-jaw muscle-fiber length and for pressure mediation and delivery between the upper and lower dental arches. A wafer is used between the teeth of opposing arches to mediate and transfer pressure during seating and cementing of dental crowns. The wafer is of one piece construction, injection molded of specifically resilient synthetic polymer composition material. One end is flat on its broadest two sides, the remainder is a similar but thinner middle layer covered on each broad side with multiple small raised hemispheres regularly arranged to abut multiple others at the base with restricted small open flat areas remaining between hemispheres. Thickness of the wafer is designed to permit jaw muscle biting pressure activity only within the limits of relaxed jaw muscle length.
