Dentsply Dispersalloy Amalgam

Dentsply Dispersalloy Amalgam

With over 25 years of proven clinical performance in millions of restorations worldwide, Dentsply Dispersalloy® is one of the most widely used dental amalgam alloys. Its unique formulation combines lathe-cut particles with silver–copper eutectic spheres, effectively eliminating the Gamma-2 phase and delivering outstanding clinical reliability.

This advanced particle technology provides exceptional corrosion resistance and significantly reduces marginal ditching, helping maintain long-term marginal integrity in stress-bearing restorations.
