<br/><br/> Attractive facial esthetics is undoubtedly a major treatment goal of orthodontics. Patients desire esthetic improvement even when their primary goal is to improve function. The purpose of this study was to evaluate orthodontists' and laypersons' perception of varying degrees of lip retraction in a three dimensional model of bimaxillary dentoalveolar protrusion cases
