An automatic dental amalgam dispenser-mixer comprising a first reservoir for silver powder and a second reservoir for mercury, dispensing and metering means for each material, and a mixer equipped with a recovery cup at its outlet. The dispensing and metering means includes a pair of separate conveyors--one for the silver powder and one for the mercury--each rotationally mounted in a sleeve having an inlet in communication with the associated reservoir and an outlet leading to the mixer. The rotational movement of each of the conveyors is separately controlled through stepping motors. An electronic control unit has a stored program for controlling the actuation of each of the conveyors and the mixer, and a keyboard and display for entry of the parameters of the desired mixture.
