Abstract

A smile is a person’s greatest beauty. A smile is an important facial expression – expressing friendliness, agreement and appreciation. Smile requires co-ordination of facial, gingival and dental components stimulated voluntarily or involuntarily by various emotions –Crawford. Smile design is the planning and pre-visualization of the desired end result of an esthetical dental treatment, targeting a more harmonious state instead of the current disharmony. It is interesting to note that smile has a role to play in the overall health and well- being of a person. According to Jane Lyle, author of the book “Body Language”, many experts are convinced that smiling and laughing is beneficial to one’s health. Psychologist Robert Zajconc has postulated that when a person smiles deliberately the brain releases neurotransmitters which can override the sadness. Paul Ekman, a researcher at the University of California supports this theory. When people’s faces are happy, heart rates slowed and the bodies become calm. Mr   Christian   Coachman,  a  Brazilian dentist/ dental  tech, first introduced the concept of DSD, a dental  treatment planning tool  used  for   enhancing  predictability,  improving  communication, and  strengthening  vision .The purpose of  this case report  was  to present an integrated  design   approach   that   took into account  functional, esthetic ,  and emotional  aspects   of  the  patient's   needs.
