重庆地区58例正常He成人X线头影测量Holdaway法分析

目的 建立重庆地区恒牙期正常He汉族成人Holdawlay分析法各项测量项目的正常值，评价其软组织的结构特征，探讨软组织侧貌的性别、地域及种族差异。方法 将58例重庆籍恒牙期正常He汉族人头颅X线侧位片扫描人计算机，用计算机定点，并自动测出Holdawav分析法的各项指标，得出均值与标准差；与北京人、日本人及白种人进行比较，作软硬组织的相关分析，建立软组织与相关硬组织的逐步回归方程。结果得出Holdawav分析法各项正常值，男女比较部分测量值有显著性差异。与北京人比较部分测量值有差异，与日本人比较各测量值无差异，与白种人比较，大部分测量值有极显著性差异；部分软、硬组织之间存在相关性。结论 软、硬组织之间既相关又独立。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。软组织测量值在不同种族间有极显著性差异。上、下颌基骨的位置，骨组织的侧貌突度都对软组织的侧貌形态有一定影响。

Cephalometric Study of Holdaway Analytical Method by Computer on 58 Adults with Normal Occlusion in Chongqing

OBJECTIVE: In order to establish the normal value of Holdaway analytical method of Chongqing and to reveal the regular patterns and characteristics concerning the craniofacial morphology. METHODS: 58 students, with permanent dentition were selected as the samples. The cephalometric images were scanned into a computer and the images were imported into the program. The cephalometric analysis were automated by the computer. The cephalometric analytical method of Holdaway was used in this study. Correlational analysis were calculated. RESULTS: The normal values of Holdaway analytical method for permanent denition on normal occlusal adults of Chongqing were established and compared with that of Pekingman, Japanese and White man. CONCLUSIONS: We found that soft cephalometric measurement values are various in sex and races and regional population. There were correlations between hard and soft tissues.
