Whereas the psychosocial benefits of orthognathic treatment for the individual patient are established, there is little data relating to social perceptions in relation to changes in facial appearance as a result of combined orthodontic and orthognathic treatment. This study aimed to investigate the social impact of combined orthodontic-orthognathic surgical correction for class III malocclusion in Caucasian subjects.
This cross-sectional study compared perceptions of facial appearance prior to and after orthognathic correction of class III malocclusion. Eighty undergraduate students were shown photographs of four Caucasian subjects (2 male and 2 female) pre- and post-orthognathic class III correction. Observers were asked to rate these subjects in relation to four different outcomes: (i) social competence (SC); (ii) intellectual ability (IA); (iii) psychological adjustment (PA); (iv) attractiveness. A mixed-model analysis of variance (ANOVA) was calculated to determine the effect of each variable.
Statistically significant differences were found in ratings of the same face before and after treatment. After treatment, faces were rated as more psychologically adjusted, more sociable, more likely to be successful and more attractive; with the mean psychological adjustment rating being associated with the most change (before treatment=8.06 [SD 2.30]; after treatment=6.64 [SD 2.03], t=2.04, p<0.001).
After combined orthodontic-orthognathic correction of class III malocclusion in Caucasians, individuals are rated by young adults as being better adjusted both psychologically and socially, more likely to be successful and more attractive.
尽管正颌治疗对个体患者的心理社会效益已得到证实，但关于正畸与正颌联合治疗导致面部外观变化的社会认知方面的数据却很少。本研究旨在调查正畸 - 正颌联合手术矫治高加索人种III类错牙合畸形的社会影响。
这项横断面研究比较了III类错牙合畸形正颌矫治前后的面部外观认知。向80名本科生展示了4名高加索受试者（2男2女）III类错牙合畸形正颌矫治前后的照片。要求观察者根据四种不同结果对这些受试者进行评分：（i）社交能力（SC）；（ii）智力（IA）；（iii）心理调适（PA）；（iv）吸引力。计算方差分析的混合模型以确定每个变量的影响。
发现治疗前后对同一张脸的评分存在统计学上的显著差异。治疗后，面部被评为心理调适更好、更善于社交、更有可能成功且更具吸引力；其中心理调适评分的均值变化最大（治疗前 = 8.06 [标准差2.30]；治疗后 = 6.64 [标准差2.03]，t = 2.04，p < 0.001）。
在高加索人种中对III类错牙合畸形进行正畸 - 正颌联合矫治后，年轻人认为个体在心理和社交方面调适得更好，更有可能成功且更具吸引力。
