摘要
目的:建立重庆地区恒牙初期正常汉族儿童硬组织各项头影测量项目的正常值,研究其颅颌面结构特征。方法:55名重庆籍恒牙初期正常汉族儿童头颅X线侧位片扫描,用计算机定点,测出硬组织的各项指标,得出均值与标准差;对SNA、SNB、ANB、FMA、FMIA、IMPA进行相关分析;将测量值与国内外部分地区进行比较。结果:硬组织的各项正常值,重庆地区男女性别比较,部分测量值有显著性差异;与国内外部分地区比较有差异;SNA、SNB、ANB、FMA、FMIA、IMPA测量值受多方面因素的影响。结论:X线头影测量的正常值存在种族、地域及性别差异,各地区应当有相应的硬组织正常值标准。
Objective： In order to establish the normal value of hard tissues of Chongqing and to reveal the regular patterns and characteristics concerning the craniofaicial morphology. Method：58 students,with early permanent dentition were selected as the samples.The cephalometric images were scanned into a computer and the images were impoerted into the program.The cephalometric analysis were automated by the computer.The cephalometric analytical on hard tissues features was used in this study.Correlational analysis for SNA,SNB,ANB,FMA,FMIA,IMPA were caculated. Result： The normal values of hard tissues for early permanent dentition on normal occlusal children of Chongqing were established and compared with that of other areas, Conclusion： We found that hard cephalometric measurement values are various in sexual and races and regional population.
