"Smile Design - The Concept of Emotional Dentistry" is a specialized book that explores aesthetic dentistry and the emotional dimension of smiles. It highlights the artistic and subjective aspects of dental treatment aimed at creating the illusion of beauty. The smile is considered the greatest beauty feature of a person, and an imperfect smile can be perceived as a physical impairment. The book emphasizes that the goal is to achieve a harmonious composition of the smile by harmonizing various aesthetic elements. Unlike tooth shaping, which focuses on the contour, position, and color of individual teeth, Smile Design prioritizes the integration of these teeth into the face and facial features. This book is aimed at professionals in the field of dentistry and offers valuable insights into the connection between aesthetics and the emotional impact of smiles.
