The exact reason for retrusion in an OA-flexed posture is not asserted with certainty. OA flexion is associated with exhalation-oriented mechanics and mandibular protrusion. OA extension is associated with inhalation-oriented spinal mechanics and a tendency toward mandibular retrusion. OA mechanics link upper cervical position with jaw position and respiratory spinal mechanics. A military-style head posture normally encourages mandibular protrusion.
