提出了一种用于自然头位(NHP)记录的摄影技术，该技术可与标准射线照相曝光相关联。它允许根据标准的颅内参考和NHP对X线片进行评估。在NHP照片上，计算软组织鼻垂线与真实垂直线之间的夹角，并使用该值绕Bolton点旋转标准X线片。该技术已应用于40例私人正畸患者，其中女性24例，男性16例，年龄7~20岁，平均12.9岁。NHP的硬组织法兰克福平面变化较大：80%的患者眼眶比孔洞低(平均与地面夹角-6°)，20%的患者眼眶比孔洞高(平均角度4°)。这一平面在NHP中的位置似乎在性别上有所不同，男性比女性更多地拥有向上的法兰克福平面。53%的NHP患者软组织法兰克福平面(耳屏-眼眶)朝上(头部伸展)。法兰克福的两架飞机从来没有在所有的主题上重合：耳屏总是比门静脉更低、更前。耳屏-眶-门角平均为6°。因此，在年轻的正畸患者中，NHP是高度可变的，与性别有关，不能从平均人群值中推断出来。然而，应该在治疗前和治疗期间对每个年轻患者进行头部位置评估，以验证治疗和成长的综合效果如何。
A photographic technique for natural head posture (NHP) recording that can be associated to standard radiographic exposures is presented. It allows the evaluation of radiographs, according to both the standard intracranial references and NHP. On the NHP photograph, the angle between the soft tissue nasion-pogonion line and the true vertical is calculated, and this value is used to rotate the standard radiograph around the Bolton point. The technique has been applied to 40 private orthodontic patients (24 females and 16 males, aged 7 to 20 years mean 12.9 years). The hard tissue Frankfurt plane in NHP showed a wide variation: 80% of the patients had orbitale lower than porion (mean angle -6 degrees relative to the ground), 20% had orbitale higher than porion (mean angle 4 degrees). The position of this plane in NHP seemed to be different in the two sexes, with more males having the Frankfurt plane going upwards than females. The soft tissue Frankfurt plane (tragus-orbitale) in NHP was directed upwards (head extended) in 53% of patients. The two Frankfurt planes were never coincident in all subjects: the tragus was always lower and more anterior than porion. On average, the angle tragus-orbitale-porion was about 6 degrees. In young orthodontic patients NHP is therefore highly variable, gender dependent, and cannot be deduced from mean population values. Nevertheless, the evaluation of head position should be performed in each young patient before and during the treatment, to verify how the combined effects of therapy and growth act.
