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. The pharyngeal airway adjuster has a number of indicators adapted to indicate the amount of forwardly and rearwardly displacement effected by the first adjustment screw and/or the amount of upwardly and downwardly displacement effected by the second adjustment screw.
