The complex rotation process of the mandible during growth is elucidated by longitudinal roentgencephalometric analyses, using metallic implants as fixed references. Contrasting development of face and mandibular shape is described in three subjects. In the so-called long face syndrome, development is characterized by increasing inclination of the mandible during growth with only moderate remodeling. In the subjects with juvenile rheumatoid polyarthritis and mandibulofacial dysostosis, the increase in mandibular inclination is moderate. However, the mandibular corpus rotates backward to an extreme extent within the more stable soft tissue matrix, giving rise to the characteristic development of angular notching with an extended angular process at the lower border.
通过使用金属植入物作为固定参考的纵向X线头影测量分析，阐明了下颌骨在生长过程中的复杂旋转过程。描述了三名受试者面部和下颌骨形状的对比发育情况。在所谓的长脸综合征中，发育的特征是下颌骨在生长过程中倾斜度增加，而重塑程度仅为中等。在患有青少年类风湿性多关节炎和下颌面部发育不全的受试者中，下颌倾斜度的增加是中等的。然而，下颌体在更稳定的软组织基质内向后旋转到极端程度，导致在下颌下缘出现具有延长角突的角切迹的特征性发育。
