Study Notes
Unit 5: Facial Aesthetics and Orthodontics
- Facial Normal Features: Facial analysis is critical for orthodontic diagnostics and treatment planning. Two situations exist: malocclusion altering facial harmony (correction needs to address both) and malocclusion without alteration (correction is focused only on malocclusion itself). Cultural and personal perception of beauty affects aesthetic considerations.
Facial Aesthetic Evaluation and Historical Factors
- Golden Proportion: Beauty combines aesthetics and harmony. 'Aisthesis' refers to the perception of beauty, while 'Harmonia' refers to proportion. Throughout history, cultures have emphasized different facial features (e.g., Egyptian emphasis on prominent features, Greek focus on proportion). Current aesthetic trends and patient preferences are also significant. Modern beauty ideals are complex, influenced by patient objectives and professional knowledge and skill.
Clinical Facial Analysis
- Assessment: Analyzing facial symmetry and function is crucial before measurements. Facial asymmetry or expressions to hide imperfections should be monitored for accurate analysis. Five factors (age, race, gender, body habitus, and personality) are essential determinants in facial analysis.
Facial Patterns, Profile Analysis and Lip Analysis
- Analysis: Cephalometric analysis, using radiographs and clinical studies, is used to analyze frontal and profile views, to study angles and facial contours, along with lip analysis for ideal patient outcomes. Facial analysis and measurements are essential to evaluate facial proportions and structures. Modern technology improves these studies.
Dental Exposure and Dentom labial Analysis
- Incisor Exposure: Incisor exposure varies depending on age and gender, ranging from 1-5 mm in repose. Dental exposure and lip position are important for aesthetic consideration in a smile.
- Incisor Edge: The incisor curve's relationship to the lower lip is often crucial for an aesthetically pleasing smile. Symmetry is a preferred aesthetic goal.
- Smile Line: Dental exposure during smiling is assessed (low, medium, or high). 3-4 mm of soft tissue is often considered a healthy 'gum-line'.
