Esthetic soft tissue profile preferences among the Japanese population
1New York University, College of Dentistry, Division of Growth and Developmental Sciences, USA.
Summary
Japanese participants preferred an orthognathic facial profile over other types. This study ranked five computer-generated facial profiles by attractiveness, finding significant differences in preferences for facial aesthetics.
Area of Science:
- Dentistry
- Orthodontics
- Facial Aesthetics
Background:
- Facial profile analysis is crucial in orthodontics and aesthetic evaluations.
- Understanding cultural preferences for facial morphology is important for treatment planning.
Purpose of the Study:
- To investigate facial profile preferences within a Japanese population.
- To rank the perceived attractiveness of different facial profile types.
Main Methods:
- A sample of 2651 Japanese adults ranked five computer-generated facial profiles.
- Profiles represented distinct types: orthognathic, bimaxillary retrusive, bimaxillary protrusive, mandibular retrognathic, and mandibular prognathic.
- Statistical analysis was used to determine significant differences in rankings.
Main Results:
- The orthognathic profile was ranked as the most attractive.
- The bimaxillary retrusive profile was the second most preferred.
- The mandibular prognathic profile was ranked as the least attractive.
- All observed differences in rank scores were statistically significant (p < 0.05).
Conclusions:
- Facial profile attractiveness preferences are distinct within the Japanese population.
- The orthognathic facial profile is highly preferred for aesthetic outcomes.
- These findings have implications for orthodontic treatment and aesthetic surgery in Japan.
