1. A method of thermoforming an oral appliance, the method comprising:
inserting a dual-layer disk into a pressure chamber of a pressure molding machine, wherein:
the dual-layer disk comprises a first layer and a second layer;
the first layer comprises a first material and the second layer comprises a second material, the first material having a higher melting point than the second material; and
the second material is cross-linked by irradiation;
positioning an oral mold on a molding platform of the pressure molding machine;
applying heat to the dual-layer disk using a heating element, wherein applying heat to the dual-layer disk causes the first material and the second material to melt;
positioning the heated dual-layer disk above the oral mold; and
applying pressure to the heated dual-layer disk to cause the first material and the second material to form over the oral mold.
