Influência do posicionamento sagital mandibular na estética facial

Abstract

Objectives: To analyze the influence of mandibular sagittal position in the determination of facial attractiveness. Methods: Facial profile photographs were taken of an Afro-descendant man and a Caucasian man, as well as an Afro-descendant woman and a Caucasian woman. These photos were manipulated on the computer using Adobe Photoshop™ CS2 to produce-from each original face-a straight profile, three simulating retrusion and three protrusion mandibular discrepancies. In all, 28 photographs were evaluated by orthodontists (n = 20), oral maxillofacial surgeons (n = 20), plastic artists (n = 20) and laypersons (n = 20). The descriptive analysis was performed by calculating the mean and standard deviation for each group. Results: The straight facial profile was met with greater acceptance by Afro-descendant male faces and female faces. Caucasian males found a lightly concave facial profile with a more prominent mandible to be the most pleasant. After an analysis of skeletal discrepancies simulations, Caucasian males also showed a preference for mandibular protrusion versus retrusion. Females, however, preferred convex over concave profiles. Conclusion: The results showed agreement between groups of evaluators in selecting the most attractive profiles. Regarding male faces, a straight profile with a slightly concave face seemed more attractive and a straight facial profile was also greatly valued. AbstractKeywords: Facial profile. Orthodontics.

Esthetic perception of facial profile changes after extraction and nonextraction Class II treatment

“…Some investigators have used photographs to analyze facial esthetics, basing the outcome of a pleasant face on several aspects, including color of skin and eyes, hair, age and ethnicity. 14,17,18 However, aspects that influence examiners' perceptions of facial attractiveness may be eliminated by using profile silhouettes. 15,19,20,21,22 The concept that orthodontic treatment by extraction of premolars damages facial profile esthetics often keeps the orthodontist back from choosing this option in devising the treatment planning.…”

Study of face pleasantness using facial analysis in standardized frontal photographs

“…However, these findings disagree with those presented in a study evaluating the attractiveness of facial profile and stated that, in general, clinicians (orthodontists and maxillofacial surgeons) were more strict about facial esthetics than non-clinician (plastic artists and laymen), although all groups have agreed on the choice of most attractive profile. 31 Thus, for more conclusive results about the degree of agreement between the assessors and the tendency of esthetic judgment between groups with different areas of expertise, it is important to emphasize that the ideal would be a group with a larger number of participants than the used in this research.…”

Perception of laypersons and dentists regarding esthetic facial changes: a systematic review

“…Facial appearance plays a significant role in the perceptions of society, and influences the level of acceptance of an individual (HAMAMCI et al, 2009;MOTTA et al, 2012;FOO et al, 2013). Facial esthetics are, therefore, a social requirement that directly influences the personal and professional life of a particular person (HAMAMCI et al, 2009;ALMEIDA et al, 2010;BARROS et al, 2012;SOARES et al, 2012;FOO et al, 2013).…”

“…Over the years, the study of the face has been increasingly appealing to dental professionals, more specifically in the field of orthodontics (JOHNSTON et al, 2005;TREVISAN;GIL, 2006;NOMURA et al, 2009; ABU ARQOUB; AL-KHATEEB, 2011;BARROSO et al, 2012), and face assessments were suggested to verify either the changes caused by growth as orthodontic treatment or facial esthetics alone (HUISINGA-FISCHER et al, 2004;SOH et al, 2005;TREVISAN;GIL, 2006;FABRÉ et al, 2009;TORSELLO et al, 2010;ABU ARQOUB;AL-KHATEEB, 2011;SILVA et al, 2011;EICHENBERGER et al, 2014).…”

“…Motivated by excessive vanity, aiming to achieve the "perfect beauty", and influenced by several media outlets, people who make the contemporary society believe they will only be accepted if they meet the beauty standards imposed. Therefore, health professionals need to become familiar with the expectations of their patients whenever interfering in facial esthetics (ALMEIDA et al, 2010), which requires emphasizing the importance of running a proper medical history investigation so to contemplate and clarify the actual complaints of patients and what encouraged them to seek treatment (MOROSINI et al, 2012).…”
