Dynamic smile visualization and quantification: part 1. Evolution of the concept and dynamic records for smile...

The "art of the smile" lies in the clinician's ability to recognize the positive elements of beauty in each patient and to create a strategy to enhance the attributes that fall outside the parameters of the prevailing esthetic concept. New technologies have enhanced our ability to see our patients more dynamically and facilitated the quantification and communication of newer concepts of function and appearance. In a 2-part article, we present a comprehensive methodology for recording, assessing, and planning treatment of the smile in 4 dimensions. In part 1, we discuss the evolution of smile analysis and review the dynamic records needed. In part 2, we will review smile analysis and treatment strategies and present a brief case report.
