摘　　要：目的调查正畸患者对姿势位微笑时上唇位置高度的主观美学评价,探讨不同年龄、性别正畸求治人群是否存在微笑美学的审美差异,以期为正畸临床提供美学参考依据。方法选取理想男、女姿势位微笑面下1/3照片各1张,利用Photoshop软件对上唇位置进行变动,形成男、女微笑系列图片各11张,设计临床电子调查问卷。随机选择于山东大学口腔医院进行正畸治疗的患者300名,由患者选出最美的姿势位微笑图片3张,进行统计学分析。结果不同年龄组患者对微笑唇位置的审美有显著性差异(P<0.05),相对于青年组,中青年组和中年组更倾向于较低的上唇位置;不同性别组患者对微笑唇位置的审美差异无统计学意义(P>0.05)。结论不同正畸患者对姿势位微笑上唇位置的审美偏好有差异,微笑的审美受到年龄的影响,医生在诊治过程中应充分考虑不同年龄患者的审美期望。Objective To investigate the subjective aesthetic evaluation of upper lip positions in a smile by orthodontic patients, and to determine whether the patient＇s age and gender were influential factors in the aesthetic assessment, so as to provide reference for clin- ical orthodontic practice. Methods A frontally posed smile photograph of a man and that of a woman were changed by adjusting the position of their upper lips with Photoshop 7.0. A series of 11 pictures were developed for males and females, respectively. Then an e- lectronic questionnaire was designed and administered to investigation. 300 subjects included in the study were all orthodontic patients from the Stomatology Hospital of Shandong University. All the subjects were asked to evaluate each image according to their own aes- thetic standards and choose the top 3 most-favored pictures for each gender. Results were statistically analyzed. Results There were statistically significant differences among different age groups （P〈0.05）. Compared with the young-aged group（ 18-30 years old）, the young and middle-aged groups （31-40 years old） and the middle-aged group （41-59 years old） preferred lower upper lip position. There was no significant difference between male and female patients when selecting the top 3 most-favored frontally posed smile（P〉0.05）. Conclusions The aesthetic evaluation of lip positions by orthodontic patients is influenced by age. Orthodontists should pay attention to the aesthetic expectations of patients at different ages during orthodontic treatment.
