Patients today are demanding cosmetic restoration not only of their anterior teeth, but of their posterior teeth as well. We are moving from a "Disease Centred" approach in the dental profession i.e. fillings to a more "Health Centred" approach i.e. restorations. To restore anything is to "improve, repair or retouch so as to bring back to original condition; to bring back to a healthy state". We must be versed in all the techniques and materials that are available to enable us to produce predictable posterior restorations.
