This study provides norms for the evaluation of individual skeletal patterns in subjects with full deciduous dentition. The method is based on the associations among correlated craniofacial measurements (S-N-A, S-N-B, NL-NSL, ML-NSL, N-S-Ba). The results are given in a graphical box-like form (floating norms). An easy practical procedure allows identification of either individual harmonious craniofacial features or anomalous deviations from the individual norm. The use of cephalometric floating norms in the deciduous dentition phase is strongly recommended for early diagnosis and treatment planning.
本研究为全乳牙列受试者个体骨骼模式的评估提供了标准。该方法基于相关颅面测量值（S-N-A、S-N-B、NL-NSL、ML-NSL、N-S-Ba）之间的关联。结果以图形化的盒状形式给出（浮动标准）。一种简单实用的程序可用于识别个体和谐的颅面特征或与个体标准的异常偏差。强烈建议在乳牙列期使用头影测量浮动标准进行早期诊断和治疗计划。
