た。Amalgam, which is a mixture of mercury and silver alloy powder, has been used as a dental filling material for many years. In other words, the amalgam obtained by mixing and kneading a predetermined amount of liquid metal mercury and silver thread alloy powder with predetermined ingredients and composition is filled into the cavity of a patient's tooth, and the alloying reaction progresses after filling. It hardens to withstand occlusion, and has been used until now because it is easier to prepare and handle than other dental alloys for casting.
