Natural head position is a standardized and reproducible position, of the head in an upright posture, the eyes focused on a point in the distance at eye level, which implies that the visual axis is horizontal. While natural head position is a standardized position, natural head posture is a physiologic position of the head, when taking the first step forward from the standing to a moving or walking posture. "Orthoposition" is characteristic for a person and reproducible, but differs among persons. Cephalometrics is constantly undergoing refinements in its techniques and analyses to improve the clinical applications. NHP, a long-proposed modification, yet not fully into practice, can be an "ideal" reference for us to improve our cephalometric interpretation. This study was done to investigate sexual difference in the data obtained, from the study between male and female subjects and to compare the data given in 10-measurement cephalometric analysis based on natural head position, with the data obtained from the present study.
