本文选择上海地区正常(牙合)恒牙列60例(男、女各30例)为研究对象,60例均拍摄X线头颅定位侧位片,应用Steioer分析法,对男、女两组各测量值计算其均数和标准差,并进行t检验,因ANB角与1—NA和1—NB之间有相关性,故可推算其Cheveron值,为临床上修正矫治方案提供参考,本资料并与北京地区和朝鲜地区的资料作了比较,从而观察到上海地区成年人的颅面形态和牙颌特征。 In this paper, we selected 60 cases of normal occlusal dentition in Shanghai area (30 males and 30 females) as subjects, 60 cases were taken X-ray skull positioning lateral radiographs, the use of Steioer analysis, male and female groups The mean and standard deviation of the measurements were calculated and t-test was performed. Because of the correlation between the ANB angle and 1-NA and 1-NB, the Cheveron value can be calculated to provide a reference for the clinical correction correction program. Compared with the data from Beijing and North Korea, the craniofacial morphology and dental characteristics of adults in Shanghai were observed.
