ABSTRACT:
A prefabricated bite block structure is provided comprising a maxillary tray and a mandibular tray, each formed from a heat-deformable thermoplastic material. The maxillary tray generally corresponds to the maxillary alveolar ridge and palate of the human anatomy and is adapted to be positioned on the maxillary alveolar ridge. The mandibular tray generally corresponds to the mandibular ridge, retromolar pad areas, mucobuccal fold areas and mucolingual fold areas of the human mandible and is adapted to be positioned on the mandibular alveolar ridge. The maxillary and mandibular trays each have protrusions terminating in a flat, planar occlusal surface that corresponds at least to the area occupied by the canines, premolars and first molars. The planar occlusal surfaces of the trays correspond approximately to the plane of occlusion as defined by certain anatomical landmarks. The occlusal surfaces of the maxillary and/or mandibular trays are also adapted to receive and retain shim members which serve to increase, to the extent of the thickness of the shim member, the vertical dimension of the protruding occlusal surfaces of the maxillary and mandibular trays.
