摘　　要：目的采用多元回归方法建立山东地区8~12岁男性儿童个体化头影测量颅颌关系浮动正常值,并探讨其临床应用方法。方法研究山东地区未接受正畸治疗的正常牙合男性儿童81例。选择在判断矢状方向和垂直方向颅颌关系中最常用的5项X线头影测量指标（SNA、SN-PP、NSBa、SN-MP、SNB）,找出其中与其余4项存在显著相关性的指标SNB;以SNB为自变量,分别建立与其余4项测量指标的直线回归方程;分别以任意4项测量指标为自变量,剩余的1项测量指标为因变量进行多元回归统计分析,计算得出5项测量指标各自的预计标准误（SE）;并对各测量指标进行多元回归统计分析,建立其个体化头影测量颅颌关系浮动正常值。结果计算得出5项测量指标各自的预计标准误（SE）,其中SNA为1.97°,SN-PP为3.32°,NSBa为3.75°,SN-MP为4.31°,SNB为2.03°。结论成功建立山东地区8~12岁男性儿童个体化头影测量颅颌关系浮动正常值,为男性儿童的早期正畸-矫形治疗,提供了一套个体化的头影测量诊断方法。Objective To provide cephalometric floating norms to evaluate the individual craniofacial patterns of the male children in Shandong area. Methods Eighty-one male children with normal occlusion in Shandong area were enrolled,ranged 8-12 years. Cephalometric measurements of SNA,SN-PP,NSBa,SN-MP and SNB were selected and analized by multiple regression. SNB,which had the highest correlation with the other indicators,was found out. Bivariate linear regression equation was established with SNB as the independent variable; multiple regression equations were established with the other indicators as the independent variables; standard errors of the estimate（SE） of each measurement was calculated by multiple regression analysis. Results The SE of SNA,SN-PP,NSBa,SN-MP and SNB were 1. 97°,3. 32°,3. 75°,4. 31° and 2. 03°,respectively. Conclusion A means by using the cephalometric floating norms to evaluate the individual craniofacial patterns of the male children in Shandong area was established. It may be helpful for the orthodontic-orthopedic diagnosis and treatment for the male children.
