摘　　要：目的研究下颌骨外侧下弧线的形态,为下颌骨外形线的相关性研究奠定基础。方法应用电子扫描仪对22例华东地区成年人下颌骨标本进行1∶1的下颌骨外侧下弧线形态扫描、定点、测量;数据以SAS(6.12Version)软件进行统计分析。结果下颌骨外侧下弧线为一条抛物曲线(Y=KX2,P<0.01),可用下颌体长(GoPg)及下面宽(GoGo)来具体描述,两者无统计学差异(P>0.05)。结论可以用数学方法通过下颌体长及下面宽来推算下颌骨外侧下弧线的形态。Objecti ve The lateral inferior arc curve of mandible,which is fundament of correlation an alysis of mandibu-lar contour,was studied in morphology.Methods By means of ele ctronic scanner,the lateral inferior arc curves of mandible(1∶1)of22adult mandi bular samples from east-china were obtained.The data abtained were analysed by S AS(6.12Version)statistical software package.Results The lateral inferior arc cur ve of mandible of adult was a piece of pal-abola(Y=KX 2 ,P<0.01)approximately,which can be described concretely by variables of mand ibular length(GoPg)and mandibular width(GoGo),both of them had no significant st atestical difference(P>0.05).Conclusion The lateral inferior arc curve of mandib le can be figured out by mandibular length and mandibular width.
