Subject: Re: [Oradlist] Natural Head Position vs Natural Head Posture
In my country, many the orthodoncist like the natural head position. We try using a mirror, but some of the patients,start smiling when they look at the mirror. Then we change our system, telling our patient to look to the horizon. Now we are using what is called the assisted natural head position, im which we ask the patient to look the horizon, and then we do little adjustment to get a better position of the head

Natural Head Position is something that orthodontists claim to be more reproducible than the natural head posture. They state that this happens because the Frankfurt horizontal is based on bony references, which theoretically could not be easily found in vivo because of the patient's overlapping soft tissue.
However, in my opinion, natural head posture depends on a series of variables that can not always be controlled (i.e.: patient stress and humor, presence of any kind of sickness, among others), not to mention the high degree of subjectiveness of the method.
I myself as an orthodontist and a radiologist don't accept the statement that natural head position is more reproducible than putting FH parallel to the horizontal plane. I am pretty shure my radiologist colleagues agree that with little training anyone can put FH parallel to the horizontal plane in a very repeatable way! I am also pretty shure that most of us radiologists prefer to use the FH as the reference plane for head positioning for lateral skull projections!;-)
