[Lateral cephalometry in Chinese population with esthetic face]

Area of Science:

• Orthodontics
• Craniofacial anatomy
• Aesthetic medicine

Background:

• Understanding the craniofacial structure of individuals with aesthetically pleasing faces is crucial for orthodontic and orthognathic surgery.
• Previous research has not fully detailed the specific hard tissue profile characteristics of Chinese adults with naturally aesthetic faces.

Purpose of the Study:

• To define the typical craniofacial hard tissue profile characteristics in young Chinese adults with aesthetically pleasing faces.
• To identify variations within this aesthetic group and compare skeletal structures between males and females.

Main Methods:

• Analysis of 100 lateral cephalograms from young Chinese adults selected for aesthetic facial appearance and normal occlusion.
• Measurement of 18 landmarks, 10 angular, 10 linear parameters, and 5 linear ratios.
• Statistical analysis to identify typical features and variations.

Main Results:

• The craniofacial structure of the aesthetic group aligns with fundamental aesthetic principles.
• Significant individual variations were observed, especially in the lower third of the face.
• The lower face profile in the aesthetic group is well-developed, exhibiting a convex, relatively straight appearance.
• Distinct differences in craniofacial skeletal structure were identified between males and females.

Conclusions:

• The study successfully characterized the typical craniofacial hard tissue profile of aesthetically pleasing faces in young Chinese adults.
• Acknowledging individual variations and sex-based differences is important for personalized orthodontic and orthognathic treatments.
• The findings provide valuable data for enhancing facial aesthetics through surgical and non-surgical interventions.
