Lip position, facial esthetics

Sažetak
Aim: Since the orthodontic movement of the teeth affects the position of the lips and the appearance of the lower third of the face, it is important to know what the public considers to be the ideal profile in order to improve facial aesthetics. Aims of the study were to compare the perception of male and female profile photographs modified by changing the sagittal position of the jaws. Furthermore, to determine if there is a statistically significant difference in the esthetic preferences among dentists and laypersons for facial profile, and to determine if orthodontic standards based on skeletal and dental Class I are in correlation with the values of attractive profiles. Material and Methods: Photographs and cephalograms of male and female models were scanned and a superimposition was done. In the Dolphin Imaging computer program, photos were modified by changing the sagittal position of the jaw by at least 4mm in der to get another 5 photos for each gender, a total of 6 photos for evaluation. The study encompasses 135 evaluators, of whom 35 were dental practitioners and 100 lay people. They were asked to rank six profiles according to their attractiveness in such a way that the most attractive profile was numbered 1, and the least attractive by 6. Results: Normal and bimaxillary protrusive profiles were judged to be highly attractive according to dental professionals and laypersons. There was a statistically significant difference in the selection of the most attractive profile. Dental professionals preferred a normal profile, while laypersons preferred a bimaxillary protrusion. Profiles with mandibular protrusion were judged as the least attractive in both groups of evaluators. Other profiles were ranked equally by both groups of raters. Conclusion: It was found that the public prefers slightly more protrusive dentofacial relationships than those based on orthodontic standards, hence a more convex profile, and anteriorly positioned lips. All evaluators were more tolerant towards the horizontal displacement of the maxilla position relative to the mandibular displacement, suggesting that the perception of successful orthodontic- surgical treatment may depend more on the correction of the mandibular position.
