Natural head position

Natural head position is a reproducible position of a head when it is in an upright position, with eyes looking straight at a mark. The concept was introduced into the field of orthodontics in the late 1950s by Moorrees and Kean. A horizontal line related to the natural head position has been recommended as the most reliable plane to study cephalometric analysis.
