One of the most important goals of orthodontic treatment is to create an esthetic, well balanced facial profile. However, the components of a well-balanced Iranian facial profile have not yet been established. The purpose of this study was to evaluate the anteroposterior lip position of the Iranian population and to compare the perception of orthodontists, dental students and orthodontic patients using a series of silhouettes with varying anteroposterior lip positions.
Average female and male silhouette profiles were constructed from the profiles of 30 Iranian men and women with a normal skeletal relationship. The lips in each average profile were protruded or retruded in 2-mm increments and the 7 images were arranged randomly. Thirty orthodontists, 30 dental students and 30 orthodontic patients were asked to score each silhouette from 1 (very bad) to 5 (very good).
Both the orthodontists and the students preferred the average profile for men and slightly more retruded lip position for women. Orthodontic patients had a wide range of preference for men and selected more retruded lip positions for women. The least-favored profile was the most protrusive in the 3 groups.
These findings suggest that Iranian orthodontists, dental students and orthodontic patients prefer an average profile for men and slightly retruded profiles for women.
正畸治疗最重要的目标之一是塑造美观、比例协调的面部轮廓。然而，伊朗人比例协调的面部轮廓构成要素尚未明确。本研究旨在评估伊朗人群的唇前后位置，并通过一系列具有不同唇前后位置的侧面轮廓图，比较正畸医生、牙科学生和正畸患者的看法。
从30名具有正常骨骼关系的伊朗男性和女性的面部轮廓构建平均的男性和女性侧面轮廓图。每个平均轮廓图中的嘴唇以2毫米的增量前突或后缩，并将这7张图像随机排列。30名正畸医生、30名牙科学生和30名正畸患者被要求对每个侧面轮廓图从1分（非常差）到5分（非常好）进行评分。
正畸医生和学生都更喜欢男性的平均轮廓图，对女性则更喜欢稍微后缩的唇位置。正畸患者对男性的偏好范围较广，对女性则选择更后缩的唇位置。最不受欢迎的轮廓图在三组中都是最前突的。
这些发现表明，伊朗正畸医生、牙科学生和正畸患者更喜欢男性的平均轮廓图，以及女性稍微后缩的轮廓图。
