The characteristics of lip-mouth region including the soft and hard tissues in smiling position with frontal fixed position photographic computer-aided analysis were studied.
The subjects were 80 persons (40 male and 40 females, age range: 17 to approximately 25 years) with acceptable faces and individual normal occlusions. The subjects were asked to take maximum smiling position to accept photographic measurement with computer-aided analysis.
The maximum smile line could be divided into 3 categories: low smile line (16.25%), average smile line (68.75%), and high smile line (15%).
The method adopting maximum smiling position to study the lip-month region is reproducible and comparable. This study would be helpful to provide a quantitative reference for clinical investigation, diagnosis, treatment and efficacy appraisal.
采用正面固定位摄影计算机辅助分析，研究微笑位时唇口区域软硬组织的特征。
选取80名受试者（男性40名，女性40名，年龄范围：17至约25岁），面部美观且咬合正常。要求受试者取最大微笑位，接受计算机辅助分析的摄影测量。
最大微笑线可分为3类：低微笑线（16.25%）、平均微笑线（68.75%）和高微笑线（15%）。
采用最大微笑位研究唇口区域的方法具有可重复性和可比性。本研究有助于为临床研究、诊断、治疗及疗效评估提供定量参考。
