福建省正常牙合成人X线头影测量的Jarabak分析

Jarabak Cephalometric Analysis for Fujian Adults with Normal Occlusion

目的建立福建籍正常牙合成年人Jarabak头影测量分析法正常值标准,研究颅面发育特征,为正畸正颌诊断与治疗提供依据。方法选择90名福建籍大学生作为正常牙合样本,男性39例,女性51例,在自然头位下拍摄头颅侧位片,使用Viewbox正畸软件进行头影测量分析,得出正常值,并分析性别差异。结果得出福建地区成年人Jarabak分析法的正常值,男性颌骨大小较女性大,但其协调性基本一致。结论 Jarabak头影测量分析法在评估患者骨骼特征、肌肉类型、畸形程度和功能改变的趋势等方面为正畸医师提供了可靠的诊断依据,有助于正畸医师预测矫治过程中面型的改变情况。

Objective To discuss the dentofacial development and features of Fujian normal adults by Jarabak cephalometric analysis ,Based on that we could provide evidences for clinical diagnosis and treatment . Metheods Using cephalometric software analyzes 90 Fujian normal adults by Jarabak cepha‐lometric under Natural Head Posture ,and compares the differences between male and female . ResuIts The normal values of Fujian normal adults measured by Jarabak were established ,Most skeletal liner measurements showed significant difference between male and female adults ,and they showed similar grow th pattern . ConcIusions According to Jarabak Cephalometric Analysis ,orthodontics can evaluate skeletal features ,muscle type ,malformation level ,and the trend of function change . It also contribute to calculate the change of facial type during orthodontic treatment process .
