摘要： 目的:在三维层面研究不同颏部与唇部位置关系对面部美观的影响。方法:选取1名侧貌协调美观的女性,利用Maya软件获得不同颏部与唇部位置关系的三维图像共35个,分别邀请正畸医师(专业组,n=50)及普通大众(非专业组,n=103)进行视觉模拟评分(VAS)。结果:以“E线”为基准,前突记为正值,后缩记为负值。两组均认为颏部与唇部位置在0 mm(即与“E线”相切)时最为美观,当唇部在+6 mm、-6 mm时及颏部在+4 mm时最不美观。不同颏部位置时,专业组评分较高的唇部突度随颏部突度的增加而增加;当唇部在+6 mm、+4 mm、-6 mm及颏部位置+4 mm时,非专业组评分均高于专业组。结论:专业组偏好稍后缩的唇部位置,而非专业组更能忍受稍突的唇部位置;两组均认为过于前突的颏部不美观;正畸医生认为与颏部突度相匹配的唇部突度是美观的;当颏部与唇部突度相对于E线移动±2 mm范围内,正畸医师及大众的评分均较高。

Abstract: Objective: To study the effect of chin and lip positions on the facial attractiveness. Methods: A woman with a charming profile was selected and 35 3D head models with different chin and lip positions were obtained by Maya software. The orthodontists (professional group, n=50) and laypeople (nonprofessional group, n=103) were chosen to score the head models by visual analogue scale (VAS). Results: Using "E Line" as the reference, the protrusion was defined as a positive value and the backward was regarded as a negative value. Both groups considered that the chin and lip protrusions were most beautiful when they were 0mm (that is, they were tangent to the "E line"). Moreover, the lip projection of +6 mm, -6 mm and the chin protrusion of +4 mm were regarded as the most unattractive. The score of the non-professional group was significantly higher than that of the professional group when the lip protrusion was +6 mm, +4 mm, -6 mm, and chin protrusion was +4 mm. Conclusion: The professional group preferred a slightly concave lip position, while the non-professional group was more tolerant of a slightly convex lip position. Both groups regard a too protuberant chin shape as unpleasant. Orthodontists believe that it is aesthetically pleasing when the chin and lip protrusions changed in accordance with each other. When the protrusion of chin and lips moved within ±2 mm relative to the E line, the aesthetic effect was highly accepted by orthodontists and the general public.
