Abstract

Due to the high price of gold and its alloys, alternative alloys of non noble metals have been developed for use in fixed dental prosthesis. These are Ni-Cr and Co-Cr alloys. Usually fixed prosthesis are joined and then covered with a ceramic layer and for this purpose good castability and adherence with ceramics are required. The castability of Ni-Cr alloys is good and so is their adherence to the ceramic layer. However, a new Ni-Cr alloy with addition of gallium has been produced. In the present work the corrosion properties of a Ni-Cr-Ga alloy in oral environments are analyzed. The results show that the addition of gallium to a Ni-Cr alloy does not produce a modification on the corrosion properties of Ni-Cr alloys.
