A dental oral appliance for use with patients who suffer with sleep disorders, to reduce or eliminate snoring and to open the airway for a sleeping individual who suffers with obstructive sleep apnea. The appliance covers the inside (lingual) of the upper teeth and has an open palate. Retention for the appliance is provided by either clasps placed over the upper right and left molars and a retainer in the anterior area or by an occlusal coverage of the upper teeth. A raised incisor ramp that extends from the incisal tip (biting edge) of the incisors toward the lingual, or posterior raised ramps, separate the posterior teeth to reduce spasm on the temporalis muscle. A transverse, transpalatal member, which extends from the inside (lingual) of the upper right molars to the inside of the upper left molars, covers the tongue, preventing it from moving upward or backward during sleep, opening the airway.
