Abstract
As the time passes by, orthodontics is paying more and more attention to facial aesthetics. However, related research is mostly in the stage of qualitative evaluation without clinical reference of specific soft tissue data. Therefore, by collecting the pre- and post-treatment photographs of 26 adult female patients, this study used image deformation technology to process the photos of a 23-year-old female patient, and two groups of facial photos were established. Then, 22 males and 27 females were selected to conduct an aesthetic evaluation to the original and processed photos by questionnaire survey. Relevant indicators of the corresponding photos were obtained. Group t-test, paired t-test, and nonparametric test were used in data calculation. For patients with high compliance, deep overbite with low angle or average angle are more suitable for fixed appliance with the bite plate, while with high angle are not suitable. The nonprofessionals prefer narrower face, more retracted lip position, and fuller chin than in the actual treatment. Among them, female evaluators prefer narrower lower face than male evaluators do. Male evaluators prefer thicker lips and chins, especially thicker lower lips than female evaluators do. Laypeople prefer narrower face, more retracted lip position, and fuller chin.
Highlights
With the rapid development of the Internet, the aesthetics has been influenced by online media
Most of the evaluations on facial soft tissue aesthetics are in the qualitative stage, including Visualized Analoge Scale, Numerical Rating Scale (NRS), Verbal Rating Scale (VRS), Likert Scale, and Q-sort
Mary-Eleni et al [6] rated the results of fixed orthodontic appliances and functional appliances by VAS, in order to study the impact of different treatment on improving the facial aesthetics of Class II patients
Summary
With the rapid development of the Internet, the aesthetics has been influenced by online media. Erefore, orthodontists are increasingly focusing on improving facial aesthetics when formulating treatment plans [4]. Most of the evaluations on facial soft tissue aesthetics are in the qualitative stage, including Visualized Analoge Scale, Numerical Rating Scale (NRS), Verbal Rating Scale (VRS), Likert Scale, and Q-sort. Mary-Eleni et al [6] rated the results of fixed orthodontic appliances and functional appliances by VAS, in order to study the impact of different treatment on improving the facial aesthetics of Class II patients. [13] rated the photos with smiles with and without buccal corridor spaces by the visual analog scale. Filho et al [16] selected 25 dentists (general clinicians and various specialties), 23 orthodontists, and 27 laypeople to evaluate smile and dental attractiveness through VAS and Q-sort. We can quantitatively compare the expectation with the actual clinical effect and differences between different groups of people
