The purpose of this study was to examine the changes in mandibular dimensions and relationship as they relate to standing height, which is one indicator of skeletal maturation. The subjects for this study consisted of twenty males and fifteen females on whom cephalograms were taken between the ages of 8 and 17 years. Basic statistics summarized the changes in standing height and the mandibular parameters from 8 to 17 years of age. Analysis of variance was used to select five parameters to describe linear and angular changes in the mandible and also to compare the mean growth profiles of each of the facial parameters selected to the growth profile for standing height. Autocorrelation analysis provided a method of assessing the predictability of the growth profiles of the facial parameters from the profile of standing height for the same individual. The findings in the present investigation indicated that (1) the growth profile of height was significantly different from that of the parameters describing mandibular length and relationship; (2) the changes in standing height are significantly different in the maximum, premaximum,, and postmaximum periods of growth in both males and females; (3) the changes in mandibular length (Ar-Pog) are significantly different in the three periods; (4) the changes in mandibular relationship were not significantly different in the maximum and premaximum periods in either males or females, while the magnitude of change in the postmaximum period tended to be smaller than the other two periods; and (5) autocorrelation analysis revealed that the growth profile of height was found to have little predictive value in determining the growth profile of any of the mandibular parameters except for Ar-Pog for females.
本研究的目的是研究下颌尺寸及关系与身高（骨骼成熟度的一个指标）之间的变化关系。本研究的对象包括20名男性和15名女性，他们在8至17岁之间拍摄了头颅侧位片。基本统计数据总结了8至17岁身高和下颌参数的变化。方差分析用于选择五个参数来描述下颌骨的线性和角度变化，并比较所选每个面部参数的平均生长曲线与身高的生长曲线。自相关分析提供了一种评估同一受试者面部参数生长曲线根据身高曲线的可预测性的方法。本研究结果表明：（1）身高的生长曲线与描述下颌长度及关系的参数的生长曲线显著不同；（2）男性和女性在生长的最大、最大前期和最大后期，身高变化显著不同；（3）下颌长度（Ar-Pog）在三个时期的变化显著不同；（4）男性和女性在最大和最大前期，下颌关系的变化无显著差异，而最大后期的变化幅度往往小于其他两个时期；（5）自相关分析表明，除女性的Ar-Pog外，身高生长曲线在确定任何下颌参数的生长曲线方面几乎没有预测价值。
