3D Artificial intelligence: Analysis of Facial Harmony Correlating Nasal shape with nasolabial angle and Dental Midline Deviation

Abstract

Background: Facial harmony is influenced by the interplay of soft and hard tissue components, with soft tissue morphology playing a critical role in aesthetics. The correlation between nasal shape, nasolabial angle, and dental midline deviation remains a significant area of exploration in orthodontics and craniofacial studies.

Methods: This review studied the three-dimensional (3D) facial analysis to examine the relationships among nasal shape, nasolabial angle, and dental midline deviation. A cohort of participants underwent non-invasive 3D scanning using the ELITE system, allowing for precise measurements of facial landmarks. Statistical analyses were conducted to identify correlations and deviations among the factors studied.

Results: The findings revealed significant correlations between nasal shape and nasolabial angle, with variations observed in patients exhibiting different dental midline deviations. Children with Class II occlusions demonstrated a more pronounced convex facial profile compared to those with Class I occlusions. The study highlighted the importance of integrating 3D analysis to understand facial aesthetics comprehensively.

Conclusion: This research underscores the relevance of a multidisciplinary approach in orthodontic treatment planning, emphasizing the necessity of considering soft tissue characteristics alongside skeletal and dental factors. The insights gained from 3D facial analysis can enhance treatment outcomes and patient satisfaction. Future studies should focus on longitudinal assessments and the application of these findings in clinical practice to optimize facial harmony in orthodontic patients.
