Anatomy & Etiological Classification of the Gummy Smile

This lesson establishes the anatomical and diagnostic foundation for correcting excessive gingival display. You will study the definition, underlying etiology, and clinical classification of the gummy smile, evaluating how gingival visibility impacts smile aesthetics. The lesson provides a detailed breakdown of mid-face muscular anatomy, focusing on the key elevator muscles responsible for upper lip retraction and excessive gum exposure.
