  • Title: AC impedance measurements on high copper dental amalgams.
    Author: Lemaitre L, Moors M, van Peteghem AP.
    Journal: Biomaterials; 1985 Nov; 6(6):425-6. PubMed ID: 4084646.
    Abstract:
    In recent years alloys with a high copper content were developed to improve the corrosion resistance of dental amalgam by elimination of the gamma 2 (Sn-Hg) phase. The purpose of the present investigation was to compare the electrochemical behaviour of high copper amalgams obtained from single composition amalgam alloys (Indiloy; Shofu, Dental Corp., Menlo Park, USA) with those that used the additive mode of copper alloying (Dispersalloy; Johnson & Johnson, East Windsor, USA).
