贵州省88名正常(牙合)青少年颅面硬组织侧貌形态分析

目的:对贵州地区88名正常(牙合)青少年颅面结构进行了研究,以获得侧位X线头影测量的正常值.方法:对贵州地区798名贵州籍中专学生进行普查,以Andrews的正常(牙合)的6项为标准,选取了88名正常(牙合)学生为研究对象,拍摄X线头颅侧位片,使用WinCeph 7.0头影测量分析系统测量颅面硬组织矢状及垂直向线距和角度等30个项目,并与全国青少年测定值比较.结果:首次建立了贵州地区的正常(牙合)青少年X线头颅测量正常值.结论:不同地区正常(牙合)青少年X线头颅测量正常值有一定的差异.

Speciation Analysis on Hard Tissue Profile of 88 Adolescents with Normal Occlusion in Guizhou Province

Objective: To study craniofacial structure of 88 adolescent with normal occlusion in Guizhou province,and to obtain normal cephalometric values in Guizhou province,and so as to provide reference for clinical and scientific research of orthodontic and orthognathic surgery.Methods: Eighty-eight students with normal occlusion were selected from 789 technical secondary school students in Guizhou province according to the standards of Andrews normal occlusion.X-ray lateral radiographic films were photographed.WinCeph 7.0 cephalometric analysis computer system was employed to study 30 items about craniofacial structure,and the data were analyzed.Results: The normal cephalometric values of adolescents with normal occlusion in Guizhou province was established for the first time.Conclusions: The cephalometric values of adolescent with normal occlusion are various in different regions.It is important to establish normal standard values of different regions to provide reference for clinical and scientific research of orthodontic and orthognathic surgery.
