Changes in hyoid position in relation to changes in mandibular inclination and craniocervical posture were studied by roentgen cephalometrics in a sample of 24 long-term complete denture wearers over a 15-year period. The measurements were made on lateral occlusion films obtained with the subjects in the sitting position and with the head oriented according to its natural balance. The changes in mandibular inclination ranged from -5.5 degrees to 8.6 degrees, with a mean of zero. The cervical column became significantly more forward inclined (mean, 5 degrees), and the craniocervical angulation became on an average 5 degrees larger. Correlation analyses indicated that the hyoid position was influenced by two postural systems: the changes in mandibular inclination and the changes in cervical and craniocervical posture. The vertical changes in hyoid position in relation to the upper face largely followed the patterns of increase or decrease in mandibular inclination, whereas the horizontal changes mainly followed the changes in cervical inclination and craniocervical angulation.
通过X线头影测量法，对24名长期佩戴全口义齿者在15年期间舌骨位置相对于下颌倾斜度和颅颈姿势变化进行了研究。测量是在受试者坐姿且头部根据其自然平衡定向时获得的侧方咬合片上进行的。下颌倾斜度的变化范围为-5.5度至8.6度，平均为零。颈椎明显更加前倾（平均5度），颅颈角度平均增大5度。相关性分析表明，舌骨位置受两种姿势系统影响：下颌倾斜度变化以及颈椎和颅颈姿势变化。舌骨相对于上脸的垂直变化在很大程度上遵循下颌倾斜度增加或减少的模式，而水平变化主要遵循颈椎倾斜度和颅颈角度的变化。
