From: Canine edge width and height affect dental esthetics in maxillary canine substitution treatment
The esthetically most pleasant (ranked as top 1) canine shape with the highest grades for the incisal width and height by all observers in the study. The canine edge width was based on the percentage of the width of the maxillary central incisor clinical crown; the canine edge height was defined as the vertical distance of the incisal edges between the maxillary canine and central incisor
