a lower body including an arcuate lower body base joining a mandibular labial wall and a mandibular lingual wall in spaced apart relation defining a lower body channel between opposing inner wall surfaces, said lower body channel having a lower dentition impression which matingly receives mandibular teeth of a lower dental arch; and at least one node disposed on a lower body base outer surface, said at least one node disposed to engage said generally flat upper body outer surface upon receipt of said maxillary teeth of an upper dental arch in said upper body channel and receipt of said mandibular teeth of a lower dental arch in said lower body channel. ### Claim 2 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface occurs on one or more of an anterior medial portion of said lower body base outer surface, a left posterior portion of said lower body base outer surface, a right posterior portion of said lower body base outer surface. ### Claim 3 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface occurs on an anterior medial portion of said lower body base outer surface. ### Claim 4 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface occurs on one of a left posterior portion of said lower body base outer surface or a right posterior portion of said lower body base outer surface. ### Claim 5 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface comprises a pair of nodes, one occurring on a left posterior portion of said lower body base outer surface and one occurring on a right posterior portion of said lower body base outer surface. ### Claim 6 (depends on 5) The oral appliance of claim 5, wherein said at least one node disposed on said lower body base outer surface comprises three nodes, one correspondingly occurring over said lower dentition impression of a right second molar of said mandibular teeth, said lower dentition impression of a left second molar of said mandibular teeth, and said lower dentition impression of a left or right central incisor of said mandibular teeth. ### Claim 7 (depends on 5) The oral appliance of claim 5, wherein said at least one node disposed on said lower body base outer surface consists of three nodes, one correspondingly occurring over said lower dentition impression of a right second molar of said mandibular teeth, said lower dentition impression of a left second molar of said mandibular teeth, and said lower dentition impression of a left or right central incisor of said mandibular teeth. ### Claim 8 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface comprises a plurality of nodes one of said plurality of nodes disposed on said left posterior portion of said lower body base outer surface and one occurring on a right posterior portion of said lower body base outer surface and one of said plurality of nodes occurring on an anterior medial portion of said lower body base outer surface. ### Claim 9 (depends on 8) The oral appliance of claim 8, wherein said plurality of nodes have an arcuate external surface. ### Claim 10 (depends on 1) The oral appliance of claim 1, wherein said lower body comprises a material selected from the group consisting of: CLEARsplint™, acrylic, ProForm®, a thermoplastic, or combination thereof. ### Claim 11 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface consists of a node occurring on an anterior medial portion of said lower body base outer surface. ### Claim 12 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface consists of a node occurring on one of a left posterior portion of said lower body base outer surface or a right posterior portion of said lower body base outer surface. ### Claim 13 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface consists of a pair of nodes, one occurring on a left posterior portion of said lower body base outer surface and one occurring on a right posterior portion of said lower body base outer surface. ### Claim 14 (depends on 1) The oral appliance of claim 1, wherein said at least one node disposed on said lower body base outer surface consists of a plurality of nodes one of said plurality of nodes disposed on said left posterior portion of said lower body base outer surface and one of said plurality of nodes occurring on a right posterior portion of said lower body base outer surface and one of said plurality of nodes occurring on an anterior medial portion of said lower body base outer surface.
