Harmony is one of the main objectives in surgical and orthodontic treatment and this harmony must be present in the smile, as well as in the face. The aim of the present study was to assess the perceptions of professionals and laypersons in relation to the harmony of the smile of patients with or without vertical maxillary alterations.
Sixty observers (oral and maxillofacial surgeons, orthodontists and laypersons) reported the degree of harmony of six smiles using an objective questionnaire and the participants indicated if there was a need for corrective surgery or not. The classification of observers was recorded on a Likert scale from 1 to 5. Mixed regression was used to determine differences between the three groups.
Statistically significant differences were found only for the harmony of the smile between the oral and maxillofacial surgeons and laypersons, with laypersons being more critical when assessing the smile. There was no statistical difference between the other groups for the harmony of the smile or the indication of corrective surgery. The patterns of greater or lesser harmony determined by observers during the smile were similar to those found in the literature as the ideal standard in relation to vertical maxillary positioning.
Laypersons had a tendency to be more critical in relation to facial harmony than surgeons, although no statistical differences were found in the other groups in relation to the harmony of the smile or indication for the corrective surgery. In addition, the patterns of greater or lesser harmony of the smile determined by the participants were similar to those found in the literature as the ideal standard in relation to vertical maxillary positioning. Overall, the present study demonstrates that adequate interaction between surgeons, orthodontists and laypersons is essential in order to achieve facial harmony with orthodontic and/or surgical treatment.

和谐是外科手术和正畸治疗的主要目标之一，这种和谐必须体现在笑容中，也体现在面部。本研究的目的是评估专业人士和非专业人士对有或无垂直上颌骨改变患者笑容和谐度的看法。
60名观察者（口腔颌面外科医生、正畸医生和非专业人士）使用一份客观问卷报告六种笑容的和谐程度，参与者指出是否需要进行矫正手术。观察者的分类记录在1至5的李克特量表上。采用混合回归分析来确定三组之间的差异。
仅在口腔颌面外科医生和非专业人士对笑容和谐度的评估上发现了统计学上的显著差异，非专业人士在评估笑容时更为严格。在笑容和谐度或矫正手术指征方面，其他组之间没有统计学差异。观察者在微笑过程中确定的和谐程度高低模式与文献中作为垂直上颌骨定位理想标准所发现的模式相似。
非专业人士相对于外科医生在面部和谐方面往往更为严格，尽管在笑容和谐度或矫正手术指征方面其他组未发现统计学差异。此外，参与者确定的笑容和谐程度高低模式与文献中作为垂直上颌骨定位理想标准所发现的模式相似。总体而言，本研究表明，外科医生、正畸医生和非专业人士之间的充分互动对于通过正畸和/或外科治疗实现面部和谐至关重要。
