| Abstract: |
A device adapted to be placed in the human mouth for treating among other things temporomandibular joint dysfunctions comprising an elongated flexible plastic body having occlusal portions at the extremities thereof, the occlusal portions being interconnected at their forward or anterior ends by a labial portion. The occlusal portions each are provided with an enlarged fluid-containing passage. The passages in the occlusal portions are interconnected by a restricted passage which transverses the labial portion of the body. The occlusal portions form enlarged cells which are adapted to be positioned between the posterior teeth on each side of the mouth, and constitute occlusal pressure responsive means for hydrostatically compensating for any differences in pressure resulting from occlusal forces applied to each of the cells by the posterior teeth of the mouth. As a result, the occlusal forces which would normally be applied to the teeth are equalized and are axially oriented. The overall effect is to eliminate compensatory contraction or adjustment of the masticatory muscles, thereby enabling those muscles to function in a less strained manner, and to establish a more physiological or undistorted skull-mandible relationship.

What is claimed is:
1. A device adapted to be placed in the human mouth for treating among other things temporomandibular joint dysfunctions comprising: an enlongated, flexible body having a continuous fluid-containing passage therein, said body including occlusal portions at the extremities thereof adapted to be positioned between the posterior teeth on each side of the mouth, the fluid-containing passage of the body being enlarged along substantially the entire length of the occlusal portions to provide occlusal pressure responsive means in the body for hydrostatically compensating for differences in pressure resulting from occlusal forces applied thereto by the posterior teeth of the mouth, and a labial portion for the body having a fluid-containing passage in communication with the enlarged fluid-containing passage in each of the occlusal portions of the body, said labial portion being joined at its ends to the forward end of each of the occlusal portions of the body and extending outwardly and laterally thereof, said labial portion being shaped to enable it to be comfortably received along the labial regions of the mouth, the fluid-containing passage of the labial portion being of reduced cross-section along substantially the entire length thereof to enable the labial regions of the mouth to easily conform to the labial portion of the body while permitting ready flow of fluid between the occlusal portions of the body to be achieved whereby any differences in the occlusal forces exerted by the posterior teeth can be readily hydrostatically equalized.
