Abstract

BACKGROUND:

It is confirmed that the characteristics of soft and hard tissue development vary largely in different vertical facial types, which reflect the development trend of the patients and the controlling degree on anchorage.

OBJECTIVE:

To evaluate the influence of different vertical facial types on the aesthetic evaluation of facial profiles in young females, and analyze the perception of facial attractiveness from different people.

METHODS:

Three beautiful females, with high, average and low mandibular angle, respectively were selected according to the measurement data of projection and the orthodontist's aesthetic appreciation. They were yellow race, bilateral facial appearance was basically symmetrical, and no other maxillofacial disease was found. They also received no orthodontic or orthognathic treatment. The profile digital photographs and cephalograms of three females were collected. The positions of soft tissue lip and soft tissue chin were altered incrementally with Dolphin Imaging and Management software. Twenty-five new pictures were generated by the small scale (2 mm per unit) modification in the sagittal direction. By using “acceptable facial appearance” as a filter, 15 orthodontists selected 11 from 25 pictures. Fifty parents of orthodontic patients, 50 orthodontic patients, and 50 amateurs were taken as the evaluators for subjective aesthetic ratings and for the assessment of the influence of vertical facial types on the facial profile attractiveness.

RESULTS AND CONCLUSION:

With low and average angle, straight profile, slightly protrude chin was perceived to be beautiful. With high angle, straight profile, slightly protrude profile was perceived to be beautiful, and evaluation results are consistent between men and women. Evaluators are in agreement when it comes to evaluating the perception of facial attractiveness of three different vertical facial types profile in young females. They also have certain difference in aesthetic tendencies, but when it comes to straight profile they share the same preference. Although different vertical facial types profile has an impact on the profile of lip and chin, but it can't represent the aesthetic preference of all evaluators.
