Stress Relaxation of Dental Amalgam Alloys,

Abstract

The Division of Dental Materials, U.S. Army Institute of Dental Research, has conducted detailed studies of the static and dynamic properties of dental amalgam alloys. Short term stress relaxation of four amalgam alloys was studied. Test materials included three L. D. Caulk products (20th Century Micro Cut, 20th Century Fine Cut and Spherical Alloy) and Johnson and Johnson's Dispersalloy. It would appear that particle morphology and alloy composition affect stress relaxation behavior of dental amalgam. Stress decay patterns enhance significantly the mechanical characterization of amalgam alloys.
