| Abstract: |
An oral appliance adapted to redirect improper positioning of the tongue and lips at the start of a swallow comprises a molded body of acrylic or similar material having an arcuate marginal segment curved to contact the occlusal surfaces of teeth of the upper dental arch, an upper tongue positioning segment and a lower tongue positioning segment. The marginal segment has thin, substantially flat and relatively wide upper side surfaces that are separated to span a prescribed range of dental arches. The upper side surfaces are tightly engaged to the side teeth by a shaped layer of light activated resin for retention while the wearer is active or at rest. The lower tongue positioning segment forms an inclined channel below the marginal segment with a posteriorly facing entrance for receiving the inferior surface of the anterior portion of the tongue and the upper tongue positioning segment forms a channel above the marginal segment with a posteriorly facing entrance for receiving the superior surface of the anterior portion of the tongue. An aperture formed in the upper tongue positioning segment directs the apex of the tongue into contact with the curved aspect of the anterior palate and soft tissue.

What is claimed is:
1. A device for oral retraining comprising:
- a body including:
- a marginal segment curved to contact the dentition of the maxillary arch comprising an anterior section and first and second side sections, each side section having a substantially flat upper surface facing posterior dentition of the maxillary arch,
- a first tongue guiding segment joined with and extending below the marginal segment including a channel forming member for directing the inferior surface of the tongue tip upward, the channel forming member having a posteriorly facing entrance for receiving the inferior surface of the anterior portion of the tongue, and
- a second tongue guiding segment joined with and extending above the marginal segment including a channel forming member in proximity to the palate for directing the superior surface of the tongue tip, the channel forming member having a posteriorly facing entrance for receiving the superior surface of the anterior portion of the tongue,
- the second tongue guiding segment including an anteriorly facing aperture in the channel forming member for guiding the tongue apex into contact with the curved aspect of the anterior palate and soft tissue, and
- the substantially flat upper surfaces of the first and second side sections of the marginal segment being dimensioned to span a prescribed range of dental arches.
