Abstract: An oral appliance that includes tongue positioning structures which are useful in treating snoring, OSA and related disorders. The invention provides a passive tongue location device which includes cavities located on the internal surface adjacent the tongue, the cavities operatively providing a retentive effect on the tongue when it is in its relaxed state. Further, the present invention provides an oral device adapted to operatively enhance the operation of a sleeping user's airway, including a carrier adapted to be positioned over at least some of the lower teeth of the user and having an interior projection over at least part of the gums of a user, the projection defining a pair of opposed cavities, the cavities being shaped and operatively adapted so that the tongue of the sleeping user will passively engage the cavities.

Abstract: An oral treatment device for sleep apnoea and snoring, including a pad adapted to rest under the tongue of a user, so as to support the tongue from below, and engage the lower surface of the tongue using a reflex action of the relaxed tongue, the tongue flow adaptation effect. Implementations also include textured surfaces on the front of the device to encourage the tongue-tongue reflex and tongue protrusion. The device is designed to be tolerated for relatively long periods of time, and minimise any disruption to sleep, while providing effective tongue positioning.
