摘　　要：目的 :建立重庆地区少年 X线头影测量 Mc Nam ara分析法正常值并对其颅颌线距值作相关分析。 方法 :选择重庆地区 13岁左右正常少年共计 5 5名 (其中男 2 7名 ,女 2 8名 ) ,拍摄头颅定位侧位片 ,建立 Mc Namara分析法正常值并作相关分析。结果 :获得重庆地区少年 Mc Nam ara分析法头影测量正常值。经成组 t检验 ,男女间有效上颌长度、有效下颌长度、下前面高、上颌突距有显著性差异 ;下颌突距、上前牙突距、下前牙突距性别差异不明显。其中有效上颌长度与有效下颌长度、上颌突距与下颌突距、有效下颌长度与下前面高分别有正相关关系 ,下前面高与下颌突距在一定条件下为负相关关系 ,并建立回归方程。 结论 :X线头影测量颅颌线距测量值之间存在一定的相关性 。Objective:To establish the normal value of McNamara cephalometric analysis in Chongqing adolescents with normal occlusion and to obtain its regression models. Methods:Fifty five Chongqing adolescents with normal occlusion (male 27 and female 28)were taken lateral cephalograms. McNamara analysis was conducted and the correlation analysis was carried out.Results: There were significant differences in the normal values of McNamara analysis between male and female Chongqing adolescents, namely the effective maxillary length, effective mandibular length, lower anterior facial height and A Np line. There were no significant differences in Pog Np line, upper incisor to point A vertical,lower incisor to A P line.There were correlations between the effective maxillary length and effective mandibular length, effective mandibular length and lower anterior facial height, A Np line and Pog Np line, respectively.When effective mandibular length was fixed,lower anterior facial height and Pog Np line was correlated.The regression models were obtained.Conclusion:There is correlation between the linear measurements of the cephalometrics values.
