摘　　要：目的:探究二次矫治行为动机因素对再治疗作用大小和相互关系。方法:有正畸治疗史的大学生填写调查问卷,经样本成分分析、单因素分析、信效度分析、因子分析,获得二次矫治动机的潜在因素,构建结构方程模型(SEM)探索性分析各因素对二次矫治动机作用大小和影响关系。结果:559名有正畸治疗史的受访者中217人有二次矫治意向(男性32.26%,女性67.74%)。结构方程模型标准化路径系数提示牙齿排列情况和牙列咬合状态对口腔功能因素的影响强度分别是0.27和0.26,影响程度较弱。牙齿排列情况对外貌因素的影响强度是0.54,影响程度一般。外貌因素、牙排列情况、口腔功能、牙列咬合状态对二次矫治需求的影响强度分别是0.84、0.68、0.73、0.66,各影响程度较强。结论:女性大学生二次矫治需求高于男性。前牙美学微笑曲线、和谐美观的面部软组织和完美的侧貌轮廓是二次矫治患者共同的心理追求。牙排列因素是二次矫治需求的基础因素。首次矫治未达预期是二次矫治需求重要的心理因素。Objective:To investigate the magnitude and interrelationship of the motivational factors for secondary orthodontic treatment.Methods:College students with orthodontic treatment history were invited to fill in the questionnaire,and the potential factors related to the motivation of secondary tre atment behaviour were obtained by sample component analysis,single factor analysis,reliability analysis and factor analysis,the structural equation model was constructed to explore and analyse the relationship between the role and influence of each factor on the motivation of secondary treatment.Results:Among the 559 cases with orthodontic treatment history 217 had secondary correction intention(32.26%male,67.74%female).The standardised path coefficients of the structural equation model suggested that the strength of influence of tooth alignment and occlusal status on oral function factors was 0.27 and 0.26 respectively,with a weak degree of influence.The strength of the influence of tooth alignment on the appearance factor was 0.54,with a fair degree of influence.The strength of influence of appearance factors,tooth arrangement situation,oral function,and occlusal status on the need for secondary orthodontic treatment was 0.84,0.68,0.73 and 0.66 respectively,each with a strong degree of influence.Conclusion:The proportion of secondary orthodontic needs was higher in the female university students than in the males.Aesthetic smile curves of anterior teeth,harmonious and beautiful facial soft tissues and perfect lateral appearance contours are the common psychol ogical pursuits of secondary orthodontic patients.Dental alignment factors are the underlying factors of secondary orthodontic motivation.Failure to meet the expectations of the first orthodontic treatment is an important psychological factor for secondary orthodontic motivation.
