Tribute to Dr. John W. McLean

The restoration of a tooth or the replacement of a missing tooth in the esthetic area is very delicate, specifically in patient cases with high lip line. At demanding patients high efforts have to be made to reduce the risk for not ideally shaped or colored restorations and/or for soft tissue discolorations in order to avoid esthetic failure. From a restorative point of view the type of reconstruction and the material it is made out of have a significant influence on the result. The current restorative material options offer many esthetic features to best copy the optical properties of teeth. The color, chroma and lightness of the esthetic materials (e.g. ceramics) are hereby important parameters. Furthermore, the translucency is a important both for the mimicking of teeth as also for the masking of discolorations. A stuctured approach for the evaluation and the establishment of the white esthetics helps reducing the risk for unpleasant surprises with the result.
In conclusion, the selection of the material and the restorative components is of great importance for all types of restorations. Clinicians and technicians need to be aware of the possibilities and also of the limitations of the current restorative options.

1. Understand the criteria that influence the esthetics of teeth and of soft tissues
2. Learn about the restorative options, their possibilities and limitations
3. Learn to select restorative options for predictable white and pink esthetic.
