PURPOSE
To establish the standard values of roentgengraphic cephalometry in children with normal occlusion in Shandong district and to make the facial model.
METHODS
156 children were selected to take lateral cephalograph, and were divided into two groups: mixed dentition and early permanent dentition. Cephalograms were analyzed for all subjects with WinCeph7.0. Data were obtained for student's t test between the two groups and between males and females.
RESULTS
The norms with derivation for all measurement of X ray cephalometrical analysis on hard tissues were established. Meanwhile, the difference between males and females was compared and the facial model of children with normal occlusion was made.
CONCLUSION
Gender difference was shown in linear measurements, with greater growth in males in general. The growing tendency of children from mixed dentition to early permanent dentition was that the maxilla of the male grows faster while the mandible of the female grows faster.
目的
建立山东地区正常牙合儿童的X线头影测量标准值并制作面部模型。
方法
选取156名儿童拍摄头颅侧位片，分为混合牙列期和恒牙早期两组。所有受试者的头颅侧位片均用WinCeph7.0软件进行分析。对两组间以及男、女之间的数据进行t检验。
结果
建立了硬组织X线头影测量分析所有测量项目的均值及标准差。同时比较了男、女之间的差异，并制作了正常牙合儿童的面部模型。
结论
在直线测量中显示出性别差异，一般男性生长量更大。儿童从混合牙列期到恒牙早期的生长趋势是男性上颌生长较快，而女性下颌生长较快。
