About Book
Designed to help practitioners develop esthetic judgment in response to increased emphasis on facial esthetics, this book addresses the fundamentals of esthetics, intraoral and extraoral means of rejuvenation, and esthetic restoration of the smile. A practical protocol of progressive esthetics is proposed, and an approach to occlusion aims at restoring functional stability and a youthful appearance.
