Fu MingQue, Zhang ZenKang, and Wang Lin. He is a Diplomate of the American Board of Orthodontics. He has lectured extensively in Chinese Stomatologic Hospitals and Dental Schools.

摘要
Topic:The Anomaly of Smile Arc and its implications on Orthodontic Diagnosis and Treatment

The smile arc, as defined by Dr. DM Sarver in his article in the 2001 AJODO, is the relationship of the curvature of the incisal edges of the maxillary incisors and canines to the curvature of the lower lip in the posed smile. Years before this article, Dr. B Erickson has presented an elegant speech of smile arc in 1997 American Association of Orthodontists annual meeting in Philadelphia, Pennsylvania. It is easy to see why a phenomenon of the maxillary incisal edge and canines curvature parallel to the curvature of the lower lip is imposing. Just look at the pictures of beautiful people in fashion magazines whose smile arc happen to parallel to the lower lip; one would be convinced that smile arc is a part of the features which makes these people beautiful.
Some elements which contribute to the phenomenon of smile arc are the arrangement of maxillary incisors and canines and the contour of the lower lip. In addition, 3 other factors also contribute to smile arc formation; (a) vertical position of the maxillary posterior teeth (b) the extent of smile and (c) the angle of photography.
In this presentation, the author will analyze and discuss how the concept of smile arc can be applied to orthodontic diagnosis and treatment. The anomalous aspects of the smile arc will be identified and remedies will be suggested and contributive factors of smile arc formation along with clinical implication in orthodontic biomechanics will be discussed.
