| Abstract: |
A tongue-thrust correction appliance positionable in a patient's mouth is provided having an upper-jaw engaging structure including two laterally spaced elements, and a shelf-like plate which is integrally molded with the laterally spaced elements for suspension across the interior of the mouth in spaced relationship to the roof of the mouth. Each of the laterally spaced elements are provided with surface conformations enhancing retentive engagement with the jaw and maintenance of the plate in suspended relationship for support of the endmost portion of the tongue on an upper surface of the plate and restricting movement of the tongue to a predetermined position against the roof of the mouth during swallowing.

Having thus described the invention, What is claimed is:
1. A tongue-thrust correction appliance comprising a body of molded material having at least two laterally spaced elements, each element therof having an upper surface conformation of elongated, channel-form adapted to interfit with corresponding upper jaw portions in retained relationship therewith and a lower surface adapted to be contactingly engaged by lower jaw teeth, and an integrally formed, thin web extending transversely between said spaced elements, said web having an upper surface which is vertically disposed relative to said spaced elements to be in vertically spaced relationship to the roof of the mouth when the appliance is positioned therein and a transverse rear edge which termiantes no further rearwardly relative to said spaced elements than a line extending transversely thereacross at a point coincident with the position of the second bicuspid teeth when the appliance is positioned in the mouth whereby the tongue may be positioned in overlying relationship to the upper surface of said web.
