Amalgam vs Composite Resin

Amalgam vs Composite Resin

For the last 150 years, amalgam has been the traditional restorative material for posterior teeth and because of its effectiveness and cost, it is still used in certain parts of the world. However, resin composites have become an aesthetic alternative to amalgam restorations and there has been a remarkable improvement of its mechanical properties to restore posterior teeth. Composite resin and amalgam are both considered as suitable materials for direct posterior filling. Presently, the use of amalgam is declining due to concerns relating to the mercury release in the body and the environmental impact following its disposal, and composite resin is used more often due to advantages such as aesthetics and tooth substance saving techniques. Composite resin has become a predominant material in all placed and replaced restoration types in several countries.
