哈尔滨地区成人正常牙合Jarabak头影测量分析研究

Study on Jarabak cephalometric analysis of normal occlusion of 56 adults in Harbin area

目的通过对哈尔滨地区成人正常牙合人群进行Jarabak头影测量分析研究,建立本地区该分析法的正常值。方法在哈尔滨市高校大学生中,筛选出生并居住于哈市的成人正常牙合人群56例,其中男30人,平均年龄22岁,女26人,平均年龄21岁,在自然头位状态下拍摄头颅侧位片,描点测量后,进行统计学分析。结果建立哈尔滨地区Jarabak分析法的正常值范围。结论所有测量项目中,角度测量指标无明显性别差异,线距测量治疗显示存在性别差异。

Objective To investigate the dentofacial features of normal adults in Harbin area with Jarabak cephalometric analysis to set up a normal value of this analysis method in this area. Methods 56 normal adults who were born and bred in Harbin（ including30 male with average age of 22 and 26 female with average age of 21） were selected for this study. Lateral cephalometric X- rays were taken under natural head position（ NHP）. Computer aided methods were used for Jarabak cephalometric analysis and statistic analysis.Results The range of normal value of Jarabak analysis in Harbin area was obtained. Conclusions The results of the study show that there are no significant differences between male and female groups in angle measurements,but there are significant gender differences in the linear measurements.
