DENTALAMALGAM INNEHALLANDE EN BLANDING AV AMALGERBART OCH ICKE-AMALGERBART SILVERHALTIGT LEGERINGSPULVER SAMT MATALLPULVER FOR FRAMSTELLNING DERAV

摘要

An improved metal powder blend and improved dental amalgams produced therefrom comprising a mechanical mixture containing controlled proportions of an amalgamatable silver-base alloy powder and a substantially non-amalgamatable eutectic alloy powder containing a controlled quantity of tin which upon trituration with mercury forms a substantially continuous matrix having dispersed therethrough discrete phases of the non-amalgamatable powder particles which impart improved mechanical properties to the resultant dental restoration.
