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。

Abstract:

Investigation of sensitive index and its standard related to the aesthetics of silhouette profile images in orthodontic patients. *DAI Xin，HOU Zhi-ming，ZHAO Zhen-jin，YAN Xiu-lin， ZHAO Yang. *Jilin Stomatological Hospital ，Jilin 132011，ChinaAbstract：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.
