Evaluation of the smile: facial and dental considerations.

PURPOSE

The purpose of this article is to establish an evidence-based evaluation of the esthetic region of the mouth, by reviewing normal values for the face, the smile line, and the teeth.

MATERIALS AND METHODS

A Medline search was performed to find evidence-based data on accepted normal ranges of facial and dental proportions. The information found was organized following a sequence of physical examinations, which then was used to develop a decision tree for diagnosis and treatment planning.

CONCLUSIONS

By following this evaluation algorithm, clinicians will be able to document a standard set of data that will reveal skeletal and dental dysmorphia, which can then follow a well-organized sequence of treatment to re-establish facial and dental harmony.
