ABSTRACT:
A novel dental composition comprises an admixture of two forms of a powdered alloy in specified proportions, i.e., a major proportion in the form of relatively smooth spheroidal particles, e.g., spheres, and a minor proportion in the form of relatively rough, irregularly shaped particles, e.g., flakes. The resulting dental composition requires less mercury for amalgamation and exhibits enhanced physical properties and handling characteristics.
