摘要： 摘要： 目的 调查年轻人对微笑美的审美认知情况。方法 建立微笑模型， 以上中切牙宽长比、 上侧切牙与中切牙牙冠宽度比、 上侧切与中切牙牙龈水平差值、 露龈量、 颊长廊宽度、 微笑线弧度作为变量分别进行一定变动， 选择 200 例年轻人对其进行评价， 计算不同性别对指标的理想值、 可接受值的下限和上限情况及差异。结果 上中切牙宽长比理想值 0.75， 可接受范围 0.65～0.85； 上侧切与中切牙牙冠宽度比理想值 0.618， 可接受范围 0.518～0.718；上侧切与中切牙牙龈水平差值理想值-0.5 mm， 可接受范围-1～0 mm； 露龈量理想值 0 mm， 可接受范围 0～2 mm； 颊长廊宽度占微笑宽度的比例理想值 0.09， 可接受范围 0.05～0.21； 协调微笑 （设为 1） 是理想的微笑线弧度， 可接受范围 0.5～1。不同性别组对微笑美的 6 个审美指标的理想值、 可接受值的下限及上限评价差异均无统计学意义。结论 6 个审美指标的理想值和可接受范围可为临床美学修复治疗提供量化标准

Abstract: Abstract:Objective To survey aesthetics cognition for smiling beauty in young people smile. Methods Smile model was established. The middle incisor width/length ratio, lateral incisor and middle incisor width ratio, difference of lateral incisor and the middle incisor gingival level, gingiva exposure, buccal corridor width and smile line radian were used as variable values to change respectively. A total of 200 young people were selected to evaluate results. The differences in index of ideal value and acceptable range between different dender groups were calculated. Results The ideal value of middle incisor width/length ratio was 0.75, and acceptable range was 0.65-0.85. The ideal value of lateral incisor and middle incisor width ratio was 0.618, and acceptable range was 0.518- 0.718. The ideal value of lateral incisor and the middle incisor gingival level difference was -0.5 mm, and the acceptable range was -1-0 mm. The ideal value of gingiva exposure was 0 mm, and the acceptable range was 0-2 mm. The ideal value of buccal corridor was 0.09, and the acceptable range was 0.05-0.21. Coordinate smile was ideal smile line (value= 1), and the acceptable range was 0.5-1. There were no statistically significant differences in smile esthetics of six ideal value indicators and acceptable ranges between different gender groups. Conclusion The ideal values and acceptable ranges of six indexes of quantitative criteria can be used for clinical treatment.
