ABSTRACT:
An oral appliance for treating sleep apnea and bruxism is formed of a maxillary tray and a mandibular tray. The maxillary tray carries a maxillary bite pad projecting downwardly toward an opposed mandibular occlusal surface. The mandibular tray carries a mandibular bite pad projecting upwardly toward an opposed maxillary occlusal surface. The maxillary bite pad is posterior to the mandibular bite pad such that upon sufficient relative posterior movement of the mandibular tray, the maxillary bite pad engages the mandibular bite pad and limits posterior movement of the mandibular tray. At least one surface, chosen from the anterior face of the maxillary bite pad and the posterior face of the mandibular bite pad, defines a guide plane disposed at an upward and forward slant. The maxillary bite pad and the mandibular bite pad are engageable at the guide plane for advancing the mandibular tray along the guide plane upon vertical closure between the trays. A smooth pad is disposed over the occlusal surface of at least one of the trays, guarding the occlusal surface from engagement with the opposed bite pad.
