The Authors have statistically evaluated (by student's t test) a series of 151 patients to evaluate the relation between the depth of Spee's curve and some skeletal cephalometric (FMA, FH and ANB) and occlusal (dental Class) parameters. The test has showed that there are not significant variations of Spee's curve depth in relation with vertical skeletal parameters (FMA and FH); on the contrary, it has showed significant variations as regards horizontal (ANB) and occlusal (dental Class) parameters. Particularly, the average value of Spee's curve of skeletal and dental III Classes has turned out to be systematically lower than that of other Classes.
作者对151例患者进行了统计学评估（采用学生t检验），以评估斯皮曲线深度与一些头颅侧位测量骨骼参数（FMA、FH和ANB）及咬合参数（牙列分类）之间的关系。检验结果表明，斯皮曲线深度与垂直骨骼参数（FMA和FH）之间无显著差异；相反，在水平（ANB）和咬合（牙列分类）参数方面存在显著差异。特别是，骨骼III类和牙列III类的斯皮曲线平均值系统地低于其他类别的平均值。
