摘要： 目的·研究不同颧突度对侧貌美观唇位置的影响。方法·选取一名符合Holdaway软组织分析法的女性，采用3D MAX软件处理得到该研究对象28个不同颧突度及唇突度的三维图像，邀请正畸医师（专业组，n42）及普通人群（非专业组，n100）进行视觉模拟评分（visual analogue scale,VAS）。结果·不同颧突度情况下，专业组评分较高的唇突度为-2 mm和0 mm，而非专业组评分较高的唇位置随颧突度的增大而更为凹陷；专业组和非专业组均认为颧突度为-2 mm时最美观，且都认为+4 mm时最不美观；侧貌凹陷时，非专业组评分均高于专业组；而侧貌较凸时，专业组评分均高于非专业组。结论·普通人群面对较为凸出的颧部时更喜爱凹陷的唇位置，而正畸医师的审美不易受其影响；人们都喜欢标准偏凹陷的侧貌；较凸的颧突度最不受大众喜爱。

Abstract:
Objective · To research the effect of malar prominence on the attractiveness of lip position. Methods · A woman conforming to the Holdaway analysis method was selected and 28 3D head models with different malar prominences and lip positions were obtained3D MAX software. Then orthodontists (professional group, n42) and laypeople (nonprofessional group, n100) were chosen to score the head modelsvisual analogue scale (VAS). Results · In the case of different malar prominence, the highest scores in the professional group were -2 mm and 0 mm in lip position, but the lip position with high scores in the nonprofessional group varied with the increase of malar prominence; -2 mm in malar prominence was the highest score in the professional group and the nonprofessional group, and +4 mm scores in malar prominence were the lowest in both groups. In the concave profile, the scores of the nonprofessional group were higher than those of the professional group, while in the convex profile, the results reversed. Conclusion · The preference of lip positions among laypeople is affectedthe increase of malar prominence; however, this will not affect the aesthetics of orthodontists. People prefer the slightly concave profile and dislike the protruding malar prominence.
