Patent ID: 11813192

Abstract:
Apparatus for reducing obstructive sleep apnea, snoring and/or nasal drainage, or improving sleep even without substantial reduction in snoring. One apparatus includes an upper member fitting portions of the interior and exterior surfaces of a user's upper dentition, and a lower member fitting similarly adjacent a user's lower dentition. The upper and lower members include molar and pre-molar extensions so that when the user bites or clenches, the upper right and lower right extensions impinge on one another in substantially overlapping fashion, as do the upper left and lower left extensions. In certain embodiments, patterned surfaces on mating right and left molar and pre-molar extensions reduce friction. The lower and upper molar and pre-molar extensions may have curved or arcuate shaped interior surfaces to provide more room for a user's tongue. Right and left sub-chambers formed in the upper and lower molar and pre-molar extensions may provide lateral space for the tongue. The oral devices may be produced by additive or subtractive manufacturing methods.
