Abstract

Abstract:

BACKGROUND: It is confirmed that the characteristics of soft and hard tissue development vary largely in different vertical facial types, which reflect the development trend of the patients and the controlling degree on anchorage.

OBJECTIVE: To evaluate the influence of different vertical facial types on the aesthetic evaluation of facial profiles in young females, and analyze the perception of facial attractiveness from different people.

METHODS: Three beautiful females, with high, average and low mandibular angle, respectively were selected according to the measurement data of projection and the orthodontist’s aesthetic appreciation. They were yellow race, bilateral facial appearance was basically symmetrical, and no other maxillofacial disease was found. They also received no orthodontic or orthognathic treatment. The profile digital photographs and cephalograms of three females were collected. The positions of soft tissue lip and soft tissue chin were altered incrementally with Dolphin Imaging and Management software. Twenty-five new pictures were generated by the small scale (2 mm per unit) modification in the sagittal direction. By using “acceptable facial appearance” as a filter, 15 orthodontists selected 11 from 25 pictures. Fifty parents of orthodontic patients, 50 orthodontic patients, and 50 amateurs were taken as the evaluators for subjective aesthetic ratings and for the assessment of the influence of vertical facial types on the facial profile attractiveness.

RESULTS AND CONCLUSION: With low and average angle, straight profile, slightly protrude chin was perceived to be beautiful. With high angle, straight profile, slightly protrude profile was perceived to be beautiful, and evaluation results are consistent between men and women. Evaluators are in agreement when it comes to evaluating the perception of facial attractiveness of three different vertical facial types profile in young females. They also have certain difference in aesthetic tendencies, but when it comes to straight profile they share the same preference. Although different vertical facial types profile has an impact on the profile of lip and chin, but it can’t represent the aesthetic preference of all evaluators.

Figures/Tables 4

2.1 评价者对美观图片数的选择情况 3组评价者对不同垂直骨面型图片中美观图片数目的选择具有倾向性，均为均角组>高角组>低角组。评价者选择的高、均、低角3组图片中美貌图片数为分别为2.99、3.2和2.67张。根据上述选择结果，将每组垂直骨面型图片评分前3名的作为美貌图片。 2.2 评价时间及最喜爱的侧貌骨面型每组评价者所花费的评价时间：家长组>成年患者组>外行组，其中家长组8-18 min，平均13 min；外行组6-14 min，平均9.1 min；成年患者组8-15 min，平均10.5 min。3组评价者对3种骨面型侧貌喜爱类型如表1。 2.3 评分信度以ICC检测信度，患者家长组、外行组和成年患者组对3种骨面型侧貌图片评分的组内相关系数ICC 系数均大于0.8，表示信度良好，结果可靠性高。 2.4 评价者总体、组间及不同性别间对3种骨面型侧貌美观图片的选择结果根据评价者对美观图片数的选择情况，每种骨面型前3名为美观侧貌，记录患者家长组、外行组和成年患者组对每种骨面型图片得分前3位的美观图片(表2-6)。表2中A6图片平均得分高于A7、A11，且得分差异有显著性意义(P < 0.05)，A7和A11图片平均得分差异无显著性意义(P > 0.05)；H6图片平均得分高于H5、H7，且得分差异有显著性意义(P < 0.05)，H5图片平均得分高于H7且得分差异有显著性意义(P < 0.05)，H7与得分排名第4、5的H8、H9图片平均得分差异无显著性意义(P > 0.05)；L6得分高于L7(P < 0.05)，L6与L4图片平均得分差异无显著性意义(P > 0.05)，L4与L7图片平均得分差异无显著性意义(P > 0.05)。表3中A6与A7、A10图片平均得分差异无显著性意义 (P > 0.05)；H6与H7、H5图片平均得分差异无显著性意义 (P > 0.05)；L7与L4、L6图片平均得分差异无显著性意义 (P > 0.05)。表4中A6与A11、A10平均得分差异无显著性意义(P > 0.05)；H6得分高于H8(P < 0.05)，H6与H9图片平均得分差异无显著性意义(P > 0.05)，H8与H9图片平均得分差异无显著性意义(P > 0.05)；L6与L4、L7图片平均得分差异无显著性意义(P > 0.05)。表5中A6与A7、A9平均得分差异无显著性意义(P > 0.05)；H6与H5得分高于H10(P < 0.05)，H6与H5图片平均得分差异无显著性意义(P > 0.05)，H10与得分第4、5、6、7名的图片平均得分差异无显著性意义(P > 0.05)；L6图片平均得分高于L5、L4(P < 0.05)，L4与H5图片平均得分差异无显著性意义(P > 0.05)且与第4、5名图片平均得分差异无显著性意义(P > 0.05)。表6结果显示男女评价者对3种青年女性不同垂直骨面型侧貌美观图片的选择结果较为一致。"
