Journal of Biomedical Materials Research, 1977 AbstractThe wear of dental amalgam was studied by single‐ and double‐pass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to two‐body abrasion than the spherical amalgams tested. The wear of amalgam was determined by resistance to penetration and by a ductile mode of surface failure over the ...
