Attractiveness of variations in the smile arc and buccal corridor space as judged by orthodontists and laymen.

Full Abstract

OBJECTIVE:
To evaluate changes in attractiveness on the basis of computerized variations of smile arcs and buccal corridors for male and female smiles judged by orthodontists and laypersons.

MATERIALS AND METHODS:
Using a visual analog scale in a Web-based survey, orthodontists and laypersons rated the attractiveness of nine digitally altered smile arc and buccal corridor variations of male and female smiles. The variations were accomplished in a clinically relevant manner and based on standards set by experienced orthodontists in a pilot web-based survey.

RESULTS:
The results indicate that both laypersons and orthodontists prefer smiles in which the smile arc parallels the lower lip and buccal corridors are minimal. Significantly lower attractiveness ratings were found for smiles with flat smile arcs and excessive buccal corridors. Flattening of the smile arc overwhelms the deleterious effects of excessive buccal corridors on attractiveness ratings.

CONCLUSIONS:
On the basis of the results of this study, care should be taken not to produce an excessively flat smile arc during orthodontic treatment.
