This procedure has an application to all types of occlusal devices. It is a novel combination of hard and soft acrylic resin. The outer shell of hard resin takes the abuse of the opposing occlusion. The thin well-controlled lining of soft resin makes it easier to seat and more comfortable to wear yet is thin enough that the entire device serves as if it were made entirely of hard acrylic resin. The detailed directions for the entire procedure make it possible to fabricate these novel devices without error.
