Properly aligned teeth and a beautiful smile are the twin goals of orthodontic treatment. Unfortunately, a change in the smile arc is sometimes an unintended consequence of proper alignment. We used 3-dimensional dental models and visualization techniques, including curve-fitting and image-processing algorithms, to analyze smile arcs with respect to different parameters. The results show that smile consonance depends greatly on the conversational distance and the angle of elevation between the viewer and the smile.
牙齿排列整齐和拥有美丽笑容是正畸治疗的双重目标。不幸的是，微笑弧度的改变有时是牙齿正确排列带来的意外结果。我们使用三维牙齿模型和可视化技术，包括曲线拟合和图像处理算法，来分析微笑弧度的不同参数。结果表明，微笑和谐度在很大程度上取决于对话距离以及观察者与微笑之间的仰角。
