[摘要]目的:建立西安地区正常牙合成人Steiner、Tweed分析法的正常值,据此分析其颅面结构的性别和地区差异,为西安地区正畸、正颌临床和科研提供参考。方法:对120例西安地区正常牙合成人(男59例、女61例)X线头颅定位侧位片进行头影测量,统计得出Steiner、Tweed分析法的均数和标准差。分析男女间差异,并将各指标均值与北京、云南地区正常牙合成人测量值进行比较。结果:①建立了西安地区正常牙合成人头影测量Steiner、Tweed分析法的正常值;②在性别对比中,只有SE值的差异有统计学意义,男性大于女性(P<0.05)。③与北京、云南地区相比,多项测量指标均有统计学差异(P<0.05)。结论:西安地区正常牙合成人颅颌面结构性别间差异不明显,地区差异显著。

Abstract:ObjectiveTo establish the cephalometric standard values ofadults with normal occlusion in Xi'an China using Steiner and Tweed method in order to provide theoretical basis for clinical diagnosis and scientific research in orthodontics and orthognathic surgery.MethodsWe measured the lateral cephalometric films of 120 adults (59 males and 61 females) with normal occlusion in Xi'an using Steiner and Tweed method by professional software. Then, the mean and standard deviation of each parameter was obtained. Next, the differences between genders were analyzed. Finally,we compared the data with those in Beijing and Yunnan area. ResultsThe cephalometric standard values of adults with normal occlusion in Xi'an using Steiner and Tweed method were established.Moreover,the parameter of SE had statistically significant difference between genders,with the larger value in male(P<0.05). There existed statistically significant differences in several parameters of adults with normal occlusion between Xi'an and other regions(P<0.05). Conclusion There are little differences in dental and facial structures of adults with normal occlusion between genders in Xi'an, however significant differences between Xi'an and other regions ......
