Patent ID: 7730891

Claim:
An intraoral mandibular advancement device to treat problems associated with sleep disorders in a user having an obstructed oropharyngeal space comprising: a maxillary appliance having: (a) a main body for attachment to a user's maxillary teeth and having a central portion; (b) a protrusive element distending from the central portion of the main body and having an anterior surface with an aspect parallel to an arc defined by the motion of the incisal edges of the user's lower incisors as they rotate around the condylar hinge axis of the user's mandible; and (c) retention means extending from the main body for retention of the maxillary appliance to a user's maxillary anterior teeth only to prevent contact on the user's posterior teeth, thereby preventing clenching forces from being exerted on the user's posterior teeth; and a mandibular appliance for attachment to a user's mandibular anterior teeth to prevent contact on the user's posterior teeth having a polymeric shell with recesses to receive at least a user's anterior mandibular teeth, thereby preventing clenching forces from being exerted on the user's posterior teeth, and having a lingual spacer extending posteriorly from the anterior teeth to contact the protrusive element of the maxillary appliance, thereby causing mandibular advancement to expand the oropharyngeal space and maintain separation of the user's upper and lower posterior teeth to prevent clenching forces on the user's posterior teeth.
