A pilot study was done to determine whether parental cephalometric variables could be used to better predict craniofacial dimensions in their offspring. The sample consisted of lateral roentgenographic cephalograms from 41 children who had been treated with functional appliances for anterior crossbites and from their respective parents. The actual mandibular prognathic growth change of each child after treatment was determined from two profile radiographs over a 3-year period. Morphologic features after treatment and those of the respective parents were compared with the observed yearly growth change, and the predictive values were calculated by means of uni- or multivariate analysis. The best fit predictive formula was obtained by the total observation of variables from both children and their parents by means of multiple regression analysis in which the correlation coefficient exceeded 0.9 despite a value of less than 0.5 when the variables were analyzed separately by simple regression analysis. Thus, to predict the craniofacial growth for a given type of child, the dimensions of the child in addition to those of his or her parents (hereditary) seem to be a valid approach.
一项初步研究旨在确定父母的头影测量变量是否可用于更好地预测其后代的颅面尺寸。样本包括41名接受功能性矫治器治疗前牙反合的儿童及其各自父母的头颅侧位X线片。通过在3年时间内拍摄的两张侧面X线片确定每个儿童治疗后实际的下颌前突生长变化。将每个儿童治疗后的形态特征及其各自父母的特征与观察到的年度生长变化进行比较，并通过单因素或多因素分析计算预测值。通过对儿童及其父母的变量进行全面观察，采用多元回归分析获得了最佳拟合预测公式，尽管在简单回归分析中单独分析变量时相关系数小于0.5，但多元回归分析中的相关系数超过了0.9。因此，对于预测特定类型儿童的颅面生长，除了其父母的尺寸（遗传因素）外，儿童自身的尺寸似乎也是一种有效的方法。
