3D measurements and comparison of facial soft tissue of Chinese Han male and female adults with normal occlusion / 实用口腔医学杂志

ABSTRACT

Objective:To study 3-dimensional facial soft tissue reference values of Chinese Han nationality adults with normal occlusion and explore the facial morphology differences between men and women.Methods:3dMD images from 30 men and 32 women of Han nationality,aged 18-35 years,with normal occlusion were analyzed and compared between the men and women on 19 linear distances,8 angular measurements and 10 linear distance ratios.Results:Linear distances concerning the width and height of facial and organic contours were larger in men(P<0.05),while the ratio of facial height to width were larger in women(P<0.05);the nasofrontal angle and nasal prominence angle were both smaller(P<0.05) but nasofacial angle were larger(P<0.05) in men than in women.Conclusion:The facial and organic contours are larger in men than in women.Men have wide-elliptical face while women have thin-elliptical one.The nose of men is more prominent than women.
