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

The average incisal display of the maxillary central incisors in young females at rest, also known as repose, typically falls within the range of 3 to 4 mm. This measurement is crucial for aesthetic judgments in dentistry as it helps guide the design of anterior restorations or evaluations of dental esthetics in smile analysis.

The 3-4 mm range represents the average amount of exposed incisal edge when the lips are in a closed position and the person is not speaking or smiling. The significance of this measurement lies in its relevance to creating a balanced and harmonious facial appearance, where the teeth should complement the lips and overall facial structure.

Understanding the dynamics of incisal display is particularly important for general dentists, as misjudgment in restoration length can lead to aesthetic incongruences that affect both the appearance and function of a patient's smile. By adhering to the average measurement established in research, dental practitioners can enhance their outcomes in care and aesthetics for their patients.
