Abstract

A dentally retained intra-oral appliance worn at night for treatment of snoring and obstructive sleep apnea. The appliance maintains the patient'"'"'s mandible in an anterior, protruded position to prevent obstruction of the pharyngeal airway. The appliance allows a limited degree of lateral movement of the mandible relative to the upper jaw in the protruded position to prevent aggravation of the patient'"'"'s tempromandibular joint and associated muscles and ligaments. The appliance preferably consists of an upper bite block conforming to the patient'"'"'s maxillary dentition, a lower bite block conforming to the patient'"'"'s mandibular dentition, and a connecting assembly secured to an anterior region of the upper and lower bite blocks for adjustably coupling the upper and lower bite blocks together.

Claims

1. A device for improving the breathing of a user comprising:

an upper arch adapted to receive at least some of the user'"'"'s upper teeth;

a lower arch adapted to receive at least some of the user'"'"'s lower teeth; and

a connector adjustably coupling the lower arch to the upper arch, the connector operable to adjust the lower arch forwardly relative to the upper arch to maintain the lower jaw of the user in a protruded, forward position, the connector operable to allow lateral motion of the lower arch relative to the upper arch in the protruded, forward position.

2. The device of claim 1, wherein the connector is removably coupled to the upper arch.

3. The device of claim 1, wherein the connector is operable to adjustably position the lower arch vertically relative to the upper arch.

4. The device of claim 1, wherein the connector is operable to allow the user'"'"'s lower jaw to move freely in a vertical direction relative to the upper arch.
