Claim:
An interoccusal sports prophylaxis comprising a core, the core including an arch shaped occlusal plate, maxillary buccal and lingual walls extending upwardly from the occlusal plate, a dentition encasement material covering the upper surface of the occlusal plate and inner faces of the maxillary buccal and lingual walls, the occlusal plate including a generally planar lower mandibular face, the dentition encasement material covering selected zones of the lower mandibular face, the selected zones being spaced from one another along the mandibular face, the occlusal plate extending below the plane of the mandibular face at the selected zones, the core including passages through the occlusal plate transverse to the plane of the mandibular face at the selected zones, the dentition encasement material covering the upper surface of the occlusal plate and the selected zones extending through the passages, the dentition encasement material conforming to the shape of tooth surfaces after the prophylaxis is fitted and when the prophylaxis is worn, whereby mandibular occlusal surfaces not registered with the selected zones are spaced from the mandibular face to provide oral breathing passages between mandibular tooth surfaces and the mandibular face when the prophylaxis is worn.
