BACKGROUND
Radiological cephalometry is an important diagnostic tool for analyzing the shape and proportions of the skull. Standardized teleradiography of the skull in posterior-anterior (PA) projection provides orientation data on the symmetry and vertical relations of the skull. The comparison of individual findings with normal values places high demands on the selection of a control group. The aim of this study was to characterize a group to be used as a standard for cephalometric comparisons.
PATIENTS AND METHODS
PA teleradiographs of 23 healthy young adults were analyzed. Distances from reference measuring points to the median sagittal plane and the orbital horizontal plane were made. All individuals showed ideal occlusion. None of the participants had been subjected to orthodontic therapy or craniomaxillofacial surgery.
RESULTS
The measurement results showed a high degree of lateral symmetry of the skeletal reference points and planes. Comparison of the vertical reference lines confirmed the symmetrical constitution of the facial skeleton.
CONCLUSION
The study group is suitable for comparison with the cephalometric evaluations of other study groups.
背景
放射学头测量是分析颅骨形状和比例的重要诊断工具。颅骨后前（PA）投影的标准化远距射线照相术提供了颅骨对称和垂直关系的定位数据。将个体发现与正常值进行比较对选择对照组提出了很高的要求。本研究的目的是描述一个可用于头测量比较的标准组。
患者和方法
分析了 23 名健康年轻成年人的 PA 远距射线照片。从参考测量点到正中矢状面和眶水平面的距离。所有个体均具有理想的咬合。参与者均未接受过正畸治疗或颅面外科手术。
结果
测量结果显示骨骼参考点和平面的侧向对称性很高。垂直参考线的比较证实了面部骨骼的对称结构。
结论
该研究组适合与其他研究组的头测量评估进行比较。
