摘要

目的探讨影响颊旁间隙大小的颅颌面软硬组织因素,为正畸临床诊断分析和治疗设计提供参考。方法选取个别正常、五官端正的学生30名,采集其姿势位微笑面像、上颌牙列模型及X线头颅定位侧位片,获得各项颅颌面软硬组织评估参数。然后采用SPSS 17.0统计分析软件对数据进行Spearman相关性检验和多重线性回归分析。结果 Spearman相关性检验结果显示,上中切牙长轴与鼻根点-上齿槽座点连线的交角(U1-NA)、下中切牙长轴与下颌平面相交之上内角(L1-MP)、下中切牙长轴与鼻根点-下齿槽座点连线的交角(L1-NB)、下颌平面角(MP-FH)、下面高(ANS-Me)、鼻下点到软组织颏下点距离(Sn-Mes)、上唇垂直高度(Sn-Stms)、下唇下缘点到软组织颏下点距离(Stms-Me)、U1暴露量以及上颌前磨牙区宽度与颊旁间隙比例有相关性(P<0.05)。多重线性回归分析结果显示,Sn-Mes、U1暴露量以及上颌前磨牙区宽度对颊旁间隙比例的影响有统计学意义(P<0.05)。结论随着下面高、微笑时上切牙暴露量以及上颌前磨牙区宽度的增加,颊旁区有减小的趋势。
        Objective To explore the factors affecting the size of buccal corridor in craniomaxillofacial soft and hard tissues,and to provide reference for clinical diagnosis and treatment design of orthodontics.MethodsA total of 30 students with individual normal occlusion and correct facial features were selected. Postural smiling faces,maxillary dentition models and X-ray lateral radiographs were collected to obtain the evaluation parameters of craniofacial soft and hard tissues. Then SPSS 17.0 statistical analysis software was used to test Spearman correlation and multiple linear regression analysis.ResultsSpearman correlation test showed U1-NA,L1-MP,L1-NB,MP-FH,ANS-Me,Sn-Mes,Sn-Stms,Stms-Me,U1 exposure and the width of maxillary premolar area were correlated with the ratio of buccal corridor(P <0.05). Multiple linear regression analysis showed Sn-Mes,U1 exposure and width of maxillary premolar area had significant effects on the ratio of buccal corridor(P < 0.05).Conclusion Buccal corridor tends to decrease with the increase of ANS-Me,U1 exposure and width of maxillary premolar area when smiling.
