【摘要】 目的:建立重庆地区恒牙期正常汉族成人硬、软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:将58名重庆籍恒牙期正常汉族人头颅X线侧位片扫描入计算机,用计算机定点,并自动测出硬、软组织的各项指标,得出均值与标准差。对SNA、SNB、ANB、FMA、FMIA测量值进行相关分析。将软组织测量值与部分硬组织测量值进行相关分析。结果:得出硬、软组织的各项测量值;与国内部分地区比较,部分测量值有差异;SNA、SNB、ANB、FMA、FMIA测量值受多方面因素的影响;部分硬、软组织之间存在相关关系。结论:X线头影测量的正常值存在地域及性别的差异,硬、软组织之间既相关又独立,且硬组织的结构形态不能完全反映软组织的侧貌外形,需要由软组织的头影测量来进行补充。更多还原

【Abstract】 Objective:In order to establish the normal value of hard and soft tissues of Chongqing and to reveal the regular patterns and characteristics concerning the craniofaicial morphology. Method:58 students,with 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 and soft tissues features was used in this study. Correlational analysis for SNA,SNB,ANB,FMA,FMIA were caculated. Result:The normal values of hard and soft tissues for permanent dentition on normal occlusal adults of Chongqing were established and compared with that of other areas. Conclusion: We found that hard and soft cephalometric measurement values are various in sexual and races and regional population.更多还原
