An intra-oral appliance is disclosed for repositioning the user's mandible anterior to the user's maxillary teeth thus opening the user's oral and pharyngeal passageway and preventing snoring and sleep apnea. The appliance is two U-shaped plates joined to form a hinge. The upper plate has a labial-buccal wall but no lingual wall, which allows anterior positioning of the tongue. The lower plate has both a labial-buccal wall and a lingual wall. The walls are pliable to reduce pressure on the user's teeth and vary in height and thickness. Lingual tabs are employed to help position the appliance. A method for using the intra-oral appliance is also disclosed.
