Miller Classification of Marginal Tissue Recession Revisited After 35 Years.

Published more than three decades ago, the original classification of marginal tissue recession described four classes of recession. For example, in Miller Class III recession, there were different scenarios in which complete root coverage could not be achieved. Today, however, newer surgical techniques have made it possible for clinicians to potentially achieve complete root coverage when interdental bone loss exists. Currently, dentistry has a better understanding of the role of interdental papilla. Therefore, this article presents a new classification of papilla form that emphasizes the significance of the width and height of the papilla. Additionally, an updated classification of periodontal terminology will be presented.
