› Smile Arc – Dr. Watson’s distinctive smile arc is characterized by the biting edges of the upper teeth following the curve of the lower lip line. When this arc is visible, smiles are perceived as more natural and aesthetically pleasing.

› Width – Broadening the smile to reveal teeth helps establish a sense of balance and symmetry in facial appearance. If the corners are overly narrow, it can disrupt the smile’s proportions and diminish facial harmony.

› Incisor Display – Refers to the visibility of the front teeth when the upper lip is naturally elevated. This allows for the display of the incisors without the appearance of a “gummy” smile.

› Facial Harmony – It matches facial proportions, symmetry, and midline alignment, enhancing the overall aesthetic appeal and highlighting the natural features of the face.
