Morphological Simulation of Different Incisal Embrasures: Perception of Laypersons, Orthodontic Patients, General Dentists and Orthodontists.

Objective: This study aimed to evaluate how different forms of incisal embrasures influence the esthetic perception of the smile, the preferences of each group of evaluators, and the influence of gingival display.

Material And Methods: Two photographs of a broad male and female smiles were digitally manipulated to remove imperfections and asymmetries. A second manipulation was performed on the four maxillary incisors, creating 3 different forms of incisal embrasures: rounded, semi-rounded and squared.
