Comparison of preferences in lip position using computer animated imaging.

Area of Science:

• Dentistry
• Orthodontics
• Aesthetic Science

Background:

• Lip position significantly influences facial aesthetics.
• Orthodontic treatments aim to improve both function and facial harmony.
• Understanding esthetic preferences is crucial for successful orthodontic outcomes.

Purpose of the Study:

• To evaluate esthetic preferences for lip position in males and females.
• To compare these preferences with each other.
• To compare preferences with a standard orthodontic reference (Ricketts' E-line).

Main Methods:

• Utilized a custom computer animation program to present various lip positions.
• Sample comprised 53 young adults (25 males, 28 females), divided into treated and untreated orthodontic groups.
• Statistical analysis included ANOVA, Scheffé tests, and t-tests for group comparisons.

Main Results:

• Females exhibited a preference for fuller lips compared to males.
• Untreated subjects showed a preference for fuller lips than orthodontically treated subjects.
• Both male and female participants preferred lip fullness exceeding the Ricketts' E-line standard.

Conclusions:

• Significant sex and treatment-related differences exist in lip esthetic preferences.
• Current orthodontic standards may not fully align with patient esthetic desires for lip fullness.
• Further research should explore the integration of patient-specific esthetic preferences in orthodontic planning.
