Abstract
A method includes forming a first layer of a disk, the first layer comprising a first material and forming a second layer of the disk by depositing a second material on the first layer. The method further includes irradiating at least the second layer of the disk to cross-link the second material. The first material has a higher melting point than the second material, and the dual-layer disk is configured to be thermoformed into an oral appliance.
Claims11
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.
