Abstract: A pharyngeal airway adjuster, or mandible positioning device, has a maxillary dentition engagement component and a mandibular dentition engagement component, each on opposite sides of a plane extending therebetween. An adjustable connection couples the maxillary dentition engagement component with the mandibular dentition engagement component. The adjustable connection has a first adjustment screw having a longitudinal axis parallel to the plane and a second adjustment screw having a longitudinal axis perpendicular to the plane. The first and second adjustable screws are independently adjustable and structured to effect horizontal and vertical displacement, respectively, of the maxillary dentition engagement component relative to the mandibular dentition engagement component.

Abstract: A mandible positioning device or pharyngeal airway adjuster has upper and lower bite blocks and a connection between the upper and lower bite blocks, the connection being manually adjustable for displacing the lower bite block relative to the upper bite block. The adjustable connection protrudes forwardly from the upper and lower bite blocks so that, in use of the device, the manually adjustable member is located and accessible in front of a patient fitted with the mandible positioning device. The manually adjustable connection has screws which are adjustable independently of one another for effecting relative horizontal and vertical displacement, respectively, of the upper and lower bite blocks.

Abstract: A dentally retained intra-oral appliance worn at night for treatment of snoring and obstructive sleep apnea. The appliance maintains the patient's mandible in an anterior, protruded position to prevent obstruction of the pharyngeal airway. The appliance allows a limited degree of lateral movement of the mandible relative to the upper jaw in the protruded position to prevent aggravation of the patient's tempromandibular joint and associated muscles and ligaments. The appliance preferably consists of an upper bite block conforming to the patient's maxillary dentition, a lower bite block conforming to the patient's mandibular dentition, and a connecting assembly secured to an anterior region of the upper and lower bite blocks for adjustably coupling the upper and lower bite blocks together.
