Evaluation of the Smile: Facial and Dental Considerations

PurposeThe 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 MethodsA 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.ConclusionsBy 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.
