The average degree difference between Frankfurt horizontal and natural head position in males is an essential measurement in orthodontics and craniofacial studies. The natural head position (NHP) refers to the orientation of the head when an individual is standing upright and has a relaxed stance, which is representative of their innate posture. On the other hand, Frankfurt horizontal is defined by a planar line that connects the lowest point of the eye socket (infraorbital rim) to the highest point of the external auditory meatus.

Research indicates that the average angular difference between these two reference lines in males is typically around 3.18 degrees. This slight but significant degree difference is crucial for orthodontic diagnosis, treatment planning, and assessing facial symmetry, as it helps clinicians understand the positioning and alignment of the jaw and associated structures in relation to the skull.

Understanding this average degree difference assists practitioners in creating accurate predictions of dental and facial changes that may arise from orthodontic treatments or surgical interventions.
