The applicability of a newly introduced non-anatomical soft and hard tissue cephalometric centroid line (S&H centroid) was investigated. The "S&H centroid" line established from 12″ × 14″ lateral cephalometric radiographs of 57 selected adults was used as a base to create a new cephalometric reference line "Centroid-Nasion". The reliability and the use of the newly created "Centroid-Nasion" as a reference line was tested against the conventional "Sella-Nasion" cephalometric reference line to evaluate the sagittal and vertical maxillary and mandibular relationship. Pearson's correlation coefficient, one way ANOVA, and Tukey multiple comparison post Hoc statistical tests were used. The digitization technique was reliable. The "Centroid-Nasion" cephalometric reference line created by utilizing the "S&H centroid" line, was found to be as useful as the conventional "Sella-Nasion" cephalometric plane in establishing and differentiating between sagittal and vertical intermaxillary relationships.
研究了新引入的非解剖学软组织和硬组织头影测量质心线（S&H质心线）的适用性。从57名选定成年人的12英寸×14英寸侧位头影测量X线片建立的“S&H质心线”被用作基础，以创建一条新的头影测量参考线“质心-鼻根点线”。将新创建的“质心-鼻根点线”作为参考线的可靠性和用途与传统的“蝶鞍-鼻根点”头影测量参考线进行比较，以评估矢状和垂直方向上颌与下颌的关系。使用了Pearson相关系数、单因素方差分析和Tukey多重比较事后统计检验。数字化技术可靠。利用“S&H质心线”创建的“质心-鼻根点线”头影测量参考线，在建立和区分矢状和垂直方向颌间关系方面与传统的“蝶鞍-鼻根点”头影测量平面一样有用。
