Multi-directional jaw displacement oral appliance

A jaw displacement oral appliance configured to be inserted in a mouth of a user to adjust the position of the user's lower jaw relative to the user's upper jaw so as to maintain an open airway to the user's throat through which the user can breathe while sleeping, said jaw displacement oral appliance comprising:

• an upper arch tray assembly including an upper tooth impression liner configured to receive an upper set of teeth of the user's upper jaw during sleep, said upper arch tray assembly having an accurate configuration with a curved front and a pair of sides that are spaced from and lie opposite one another;
• a lower arch tray assembly including a lower tooth impression liner configured to receive a lower set of teeth of the user's lower jaw during sleep, said lower arch tray assembly having an arcuate configuration with a curved font and a pair of sides that are spaced from and lie opposite one another;
• and
• an intermediate arch tray assembly lying between said upper and said lower arch tray assemblies and having an arcuate configuration with a curved front and a pair of sides that are spaced from and lie opposite one another,
• said upper, said intermediate and said lower arch tray assemblies lying one above the other, and said upper arch tray assembly having a first coupler located at each of the pair of sides thereof and said intermediate arch tray assembly having a second coupler located at each of said pair of sides thereof and being pivotally connected in interlocking engagement to respective ones of said first couplers to prevent said upper arch tray assembly from being sated from said intermediate arch tray assembly and to establish a hinge at which said upper arch tray assembly is rotated with the user's upper set of teeth through an angle relative to said intermediate and said lower arch tray assemblies such that said upper arch tray assembly pivots upwardly and away from said intermediate and said lower arch tray assemblies and the user's lower set of teeth when the user's month is opened during sleep,
• wherein the first coupler that is located at each of the sides of said upper arch tray assembly is a catch having a catch hole formed therein and the second coupler that is located at each of the sides of said intermediate arch tray assembly includes a pair of pins that are axially aligned with one another and snapped into receipt by and into said interlocking engagement with said catch at the catch hole thereof so as to establish said hinge at which said upper arch tray assembly is rotated, said catch hole having a size that is higher in a vertical direction than a cross section in the vertical direction of said pair of pins to permit said pair of pins to move vertically through said catch hole and said upper arch tray assembly to correspondingly move up and down relative to said intermediate and lower arch tray assemblies when the user's mouth is opened and closed during sleep.
