1. A method of making an occlusal splint having two layers of of resin material sized and shaped to be worn on the upper arch of the mouth over the teeth comprising the steps of molding an upper layer of resilient resin material to conform to the shape of the upper teeth and to be retained thereon, forming a lower layer of a cold-cure resin material which is built up on the upper layer, and shaping the lower surface of the lower layer so that the lower surface of the splint engages the upper surface of the lower teeth at a time when the condyls of the wearer are in their retruded rest position and said areas of engagement are all below the plane of the lowermost edges of said upper teeth. 2. The method of claim 1 wherein said upper resilient layer extends above the greatest curvature of at least some of the upper teeth. 3. The method of claim 1 wherein said upper layer is formed of acrylic resin.
