Oral appliance

An oral appliance comprising:

• an upper arched frame arranged to be positioned within a mouth proximate an upper dentition when the upper arched frame is positioned in the mouth, the upper arched frame comprising a first tab and a second tab, the first tab and the second tab being positioned, with respect to each other, on opposite sides of a plane substantially bisecting the upper arched frame, wherein the upper arched frame does not deform when heated to 100 degrees Celsius;
• an upper moldable tray coupled to the upper arched frame such that the upper moldable tray extends beyond cuspids of the upper dentition when the upper arched frame is positioned in the mouth, the upper moldable tray arranged to deform when heated such that the upper moldable tray is configured to receive the upper dentition;
• a lower arched frame arranged to be positioned within the mouth proximate a lower dentition when the lower arched frame is positioned in the mouth, the lower arched frame comprising a third tab extending from the lower arched frame, wherein a coupling between the first tab and the third tab exerts a tensile force on the lower arched frame that pulls the lower arched frame in an anatomically anterior direction in the mouth, wherein the third tab is distal to the first tab when the upper arched frame and the lower arched frame are positioned in the mouth, wherein the lower arched frame does not deform when heated to 100 degrees Celsius;
• and
• a lower moldable tray coupled to the lower arched frame such that the lower moldable tray extends beyond cuspids of the lower dentition when the lower arched frame is positioned in the mouth, the lower moldable tray arranged to deform when heated such that the lower moldable tray is configured to receive the lower dentition.
