    摘要: A corrosion-resistant dental alloy is disclosed which has improved handling characteristics during the filling of a dental cavity. The alloy is a substantially uniform blend of three types of particles having the same chemical components, but differing in morphology and, optionally, in proportions of components. One type of particle is spherical or spheroidal in form. The second type of particle is a randomly-shaped microcrystalline form. The third type of particle is a flake-like particle. Handling characteristics of an amalgam prepared from such three particles can be adjusted to suit the requirements of the user by varying the relative proportions of the three types of particles while still retaining the corrosion resistance of the particles.

    摘要: An improved dental composition comprises an admixture in specified proportions of two powdered alloys of specified composition, one in the form of spheres, the other in the form of irregularly-shaped particles such as flakes. When the admixture is amalgamated with mercury, a corrosion-resistant dental amalgam having enhanced mechanical properties and handling characteristics is produced.

    摘要: 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.
