What is the average incisal display of the maxillary central incisors in 20-year-old females at rest?

The average incisal display of the maxillary central incisors at rest in 20-year-old females typically falls between 3 to 4 mm. This measurement represents the amount of the incisal edges of the upper front teeth that are visible when the lips are at rest. Research and clinical observations indicate that this range is considered optimal for aesthetic balance and harmony within the smile, particularly in young adult females, where facial proportions and tooth positioning are often closely tied to perceptions of beauty.

The choice of 3-4 mm reflects a balance between visibility and the natural appearance of the smile, enhancing both functionality and esthetics. It is important for dental professionals to understand these measurements to plan effective cosmetic and restorative dental procedures. Adjustments beyond this average can lead to issues with aesthetics, bite dynamics, and patient comfort.

Therefore, recognizing this average incisal display enables practitioners to guide patients toward ideal treatment outcomes, supporting both their functional needs and cosmetic desires.
