牙齿矫正术的一个基本目标是改善微笑，但没有客观的标准来评估唇齿关系，建立治疗目标或衡量治疗结果。在这里，我们提出了一种方法来数字化测量正畸患者的微笑特征。具体来说，就是测量“摆姿势的微笑”。根据定义，摆姿势的微笑是自愿的，而不是由情绪引起的。它可以是一种有学问的问候，也可以是一种绥靖的信号，而且可以持续下去。摆姿势的微笑是可靠的重复。微笑测量的多媒体计算机程序，我们开发的基础上的实用性的微笑照片和评估的唇齿特征的微笑治疗和未治疗的患者的研究。在计算机屏幕上，一个网格，或微笑网格，使用水平和垂直线来测量微笑的11个属性。并非所有具有示例性石膏模型的矫正“良好治疗”的患者在微笑时都表现出期望的前牙显示。我们认为，一个不紧张的构成微笑的摄影分析可能是一个标准的正畸记录。
A fundamental goal of orthodontics is to improve the smile, but no objective criteria exist to assess the lip-teeth relationship, establish objectives of treatment or measure treatment outcome. Here we propose a method to digitally measure the smile characteristics of orthodontic patients. Specifically, the 'posed smile' is measured. By definition the posed smile is voluntary and not elicited by an emotion. It can be a learned greeting or a signal of appeasement and can be sustained. The posed smile is reliably repeatable. The multimedia computer program for smile measurement we developed was based on studies of the utility of the smile photograph and the assessment of the lip-teeth characteristics of the posed smile in treated and untreated patients. On the computer screen a grid, or smile mesh, employs horizontal and vertical lines to measure eleven attributes of a smile. Not all orthodontically 'well-treated' patients with exemplary plaster casts exhibit desirable anterior tooth display while smiling. We suggest that the photographic analysis of an unstrained posed smile might be a standard orthodontic record.
