  • Patent number: 5752822
    Abstract: An apparatus for relieving upper airway disorders and related problems is shown and described. A tongue positioning extension is provided on a dental orthotic, the extension being positioned under a user's tongue on either side of the user's mouth. The extension is configured to elevate a tongue of the user, the tongue resting on an upper surface of the extension. The extension has a sufficient depth to prevent the tongue from moving below the extension, but is sufficiently narrow to prevent the extension from impinging on the tissues of the floor of the mouth. An upper surface of the extension is convex and polished, and edges of the extension are rounded, to allow the tongue to move easily and comfortably to the upper surface. By elevating the tongue in this manner, restriction of the upper respiratory passages is relieved, resulting in a variety of benefits to the user.
