摘要目的 探讨正畸患者下颌突度理想值和容忍范围两个维度审美评价的影响因素.方法 选择226例正畸患者进行下颌突度审美评价的电子问卷调查,采用二分类Logistic回归分析影响患者理想值和容忍范围审美评价的因素.结果 患者对女性下颌后缩容忍边界值的审美评价受年龄(OR1.360)和矫治史(OR2.849)的影响;患者对男性下颌后缩容忍边界值、女性下颌前突容忍边界值的审美评价受矫治史(OR分别为2.557和2.845)的影响;患者对男性下颌前突容忍边界值的审美评价受年龄(OR1.347)和矫治史(OR2.310)影响;患者对男性下颌突度理想值的审美评价受年龄(OR1.420)的影响.结论 正畸患者对下颌突度的审美评价受其年龄和矫治情况的影响,不受性别、学历、婚姻状况和面型特征的影响.

abstractsObjective To explore the influential factors of esthetic evaluation of mandibular prominence by orthodontic patients from two dimensions (ideal value and tolerance range).Methods 226 orthodontic patients were investigated by an electronic questionnaire of esthetic evaluation of mandibular prominence.Binary logistic regression was adopted to analyze the influential factors.Results The tolerable boundary value for female mandibular retrognathism was affected by age (OR1.360) and orthodontic history (OR2.849).The tolerable boundary value for female mandibular prognathism and male mandibular retrognathism were found to be affected by orthodontic history (OR2.557 and 2.845,respectively).The tolerable boundary value for male mandibular prognathism was affected by age (OR1.347) and orthodontic history (OR2.310).The ideal value of male mandibular prominence was affected by age (OR1.420).Conclusions Orthodontic patients' esthetic evaluation of mandibular prominence is influenced by age and treatment condition,but not by sex,education level,marital status and personal profile.
