为了建立云南省正常恒牙牙合人X线头影测量均值 ,探讨本地区正常牙合青少年颅面结构特征 .在对云南省大、中专学生普查的基础上 ,挑选出 12 8名正常牙合样本 ,对每一样本进行电子计算机化X线头影测量 ,得出本地区正常测量均值 ,对所有测量值进行统计学处理及分析 ,并与北京地区测量比较 .结果 :首次建立了我省正常牙合X线头影测量均值 .与北京地区相比 ,云南省正常牙合青少年具有南方人多具有的相对凸面形特征 .
In order to establish the average value of occlusal X-ray cephalometric measurement of normal permanent teeth in Yunnan Province and explore the features of craniofacial structure of normal occlusion adolescents in Yunnan Province.On the basis of general survey of students in secondary and secondary schools in Yunnan Province, 12 8 normal occlusion samples , The computerized X-ray cephalometric measurement was performed on each sample to get the normal measurement average in this area, all the measurements were statistically processed and analyzed, and compared with the measurement in Beijing.Results: The first time we established the normal occlusion X-cephalometry mean.Compared with Beijing, Yunnan Province, normal occlusion of adolescents with southerners have more relative convex shape.
