摘　　要：目的研究能够敏感反映患者侧貌美观程度的头影测量指标及其标准。方法中国医科大学口腔医学院正畸科2002—2005年117例矫治后患者侧貌剪影图,经16名正畸医师、63名大学生进行美观程度评分,按评分分为高分组和低分组,测量两组患者10项头影测量指标,分析组间各项指标的差异,通过Logistic回归分析,筛选与颜面侧貌美观程度密切相关的指标。结果高分组U1-AP(6.80±1.87)mm,L1-NB(3.29±2.30)mm,FMIA(56.56±6.70)°;低分组U1-AP(8.7±2.17)mm,L1-NB(4.20±3.88)mm,FMIA(49.50±10.28)°,3项指标在两组间均有统计学差异(P均<0.05),其余7项指标组间均无统计学差异(P均>0.05)。Logistic回归分析结果显示,U1-AP值与侧貌美观程度有显著相关性。结论上牙突度是影响侧貌美观的关键因素,治疗目标应以U1-AP突距(6.80±1.87)mm为参考标准。Objective Analyze sensitive indexes and its standard related to aesthetics of silhouette profile images in orthodontic patients.Methods A total of 117 cephalometric radiographs were evaluated by 16 orthodontists and 63 undergraduates and were divided into two groups according to scores.Ten dentoskeletal tissue indexes were calculated in high-score and low-score patients and the difference of indexes between two groups was analyzed.Logistic regression analysis was carried out to obtain sensitive indexes.Results U1-AP was(6.80 ± 1.87)mm,L1-NB was(3.29 ± 2.30)mm,FMIA was(56.56 ± 6.70)°in high-score group,and U1-AP was(8.70 ± 2.17)mm,L1-NB was(4.20 ± 3.88)mm,and FMIA was(49.50 ± 10.28)°in low-score group.There were significant differences in three indexes between two groups(P < 0.05),and there was no significant difference in other seven indexes(P > 0.05).U1-AP was significantly related to silhouette profile aesthetic.Conclusion Maxillary incisor is an important factor affecting profile aesthetics and U1-AP is emphasized in design and treatment.
