A morphometric analysis of the posed smile

摘要: A fundamental goal of orthodontics is to improve the smile, but no objective criteria exist assess lip-teeth relationship, establish objectives treatment or measure outcome. Here we propose a method digitally smile characteristics orthodontic patients. Specifically, 'posed smile' measured. By definition posed voluntary and not elicited by an emotion. It can be learned greeting signal appeasement sustained. The reliably repeatable. multimedia computer program for measurement developed was based on studies utility photograph assessment in treated untreated On screen grid, mesh, employs horizontal vertical lines eleven attributes smile. Not all orthodontically 'well-treated' patients with exemplary plaster casts exhibit desirable anterior tooth display while smiling. We suggest that photographic analysis unstrained might standard record.
