ABSTRACT
Objective: To Three-dimensionally Evaluate The Facial Harmony In Orthodontic Patients With Vertical Growth Pattern. Methods: Cone-beam Computed Tomography (CT) Scans Were Obtained In 10 Adults (4 Men, 6 Women) With Vertical Growth Pattern, And Reconstructed Into 3-dimensional (3D) Models By Using A 3D Image Software. 3D Position Of 12 Hard Tissue Landmarks, 3 Midline And 9 Pairs Of Bilateral Landmarks, Were Identified In 3D Coordination System, And Their Right And Left Differences Were Calculated And Analyzed.

Results: The Right And Left Difference Values Derived From The Study Indicated A Degree Of Facial Asymmetry In The Vertical Growers . The Lateral Ramal Inclination Was The Most Asymmetric Value.

Conclusions: A Degree Of Facial Asymmetry Exists In The Vertical Growers. The Lateral Ramal Inclination Is A Significant Parameter In The Assessment Of Facial Asymmetry In The Vertical Growers. Facial Asymmetry Has A Tendency To Increase According To The Lower And Lateral Positioning Of The Landmarks In The Face. There Is A Tendency Towards Left-side Dominance.
