摘要： 目的: 使用3dMD立体摄影技术采集面部立体图像,模拟改变唇部突度,比较口腔正畸医师、口腔全科医师与普通人3组观察者对面部美学评价的差异。方法: 选择1名女性志愿者,拍摄自然头位面部三维图像,利用软件模拟唇部沿矢状向离开VSL线向前后移动,移动幅度为2 mm,最大幅度在VSL线前、后6 mm。观察者纳入口腔正畸医师组、口腔全科医师组、普通人3组共268人,进行视觉模拟评分法（visual analogue scale/score,VAS）评价。使用固定效应模型进行统计,分析3组观察者对面部美学评分的差异。采用SAS 9.4软件包进行数据分析。结果: 上、下软组织唇突点在VSL线上时,3组观察者评分最高且无统计学差异。唇前突于VSL线前6 mm和线后6 mm时,3组观察者的评分低且无显著差异。唇后缩每2 mm,3组评分平均下降1.3861;唇前突2 mm,3组评分平均下降1.8961;每一幅度变化均有统计学差异（P<0.05）。以VAS评价中位数5分以下作为不可接受的面部美学得分,口腔正畸医师组和普通人组在唇前突于VSL线前4 mm时评分低于5分,3组观察者在唇前突于VSL线前6 mm时评分低于5分。3组观察者在唇后缩于VSL线后4 mm以上时,评分均低于5分。以观察者不同性别分析唇前突对面部美学的影响,男性观察组在唇前突于VSL线前2 mm时,平均评分较女性观察组低;女性观察组在唇后缩于VSL线后4 mm以上时,评分较男性观察组低。结论: 唇部位置对面部美观评价有显著影响,不仅唇前突影响面部美观,唇部后缩同样影响面部美观。不同观察者对唇部突度影响面部美观的评价有显著差异,提示口腔正畸医师在确定正畸治疗目标时,需要更多与患者沟通,以提高治疗满意度。

Abstract: PURPOSE: To collect facial stereo images of different lip protrusion by using three dimensional surface imaging device, and investigate facial aesthetic evaluation and differences between orthodontists, general dentists and laypeople. METHODS: In this study, one college student was recruited to take a three-dimensional image of the natural head and face. The software was simulated with a gradient of 2 mm to make the soft tissue lips move back and forth along the sagittal axis from the VSL line.The movement limit was 6 mm in front of and behind the VSL line. The observers included orthodontists, general dentists and laypeople. The data were analyzed with SAS 9.4 software package,visual analog scoring (VAS) was used for evaluation, and fixed-effect model was used for statistical analysis. RESULTS: The results showed that when the lip was on the VSL line, it got the highest scores amount all three groups and had no significant difference.When the lip became protrusive or retractive, it had negative impact on facial esthetics. There were significant differences in the scores of three groups in every 2mm of lip protrusion and lip retraction(P<0.05). VAS 5 points or less were used as the unacceptable facial aesthetic score. The results showed that lip protrusion was 4 mm before the VSL line in the orthodontist group and less than 5 in the laypeople group . When the lip protruded 6mm before the VSL line and retracted 4 mm behind the VSL line, the scores of the three groups were lower than 5 points. The results also showed that male evaluation of lip protrusion 2 mm before the VSL line had a lower score than female; On the other hand, female evaluation of lip retraction behind the VSL line above 4mm had a lower score than male. CONCLUSIONS: Lip position has significant effect on facial aesthetics. Different observers had significant differences in the evaluation of lip position on facial aesthetics. It is suggested that orthodontists need more communication with patients in determining the target position of orthodontic treatment to improve treatment satisfaction.
