The purpose of this investigation was threefold: 1) Determine if a person's smile improves with orthodontic treatment, 2) Determine if the amount of improvement varies among clinicians, and 3) Determine reasons for the variances. Results of this investigation were: 1) In all four categories of evaluation there was a definite improvement in the average scores from the pretreatment to the posttreatment evaluation. 2) The amount of improvement varied from orthodontist to orthodontist. 3) Some patients did not show improvement in one or more of the areas evaluated. 4) A profile photograph is not a reliable source of information to determine what a smile will look like. 5) To maximize the potential for improving a patient's smile, we must consider moving maxillary anterior teeth vertically.
1）确定正畸治疗后患者的笑容是否有所改善；2）确定不同临床医生治疗效果的改善程度是否存在差异；3）确定差异产生的原因。本研究的结果如下：1）在所有四类评估中，从治疗前评估到治疗后评估，平均分数都有明显提高。2）不同正畸医生的改善程度各不相同。3）部分患者在一项或多项评估领域未表现出改善。4）侧面照片并非判断笑容最终效果的可靠信息来源。5）为了最大程度地改善患者的笑容，我们必须考虑垂直移动上颌前牙。
