A modern amalgamator is a computerized mixing system that works under the control of a microprocessor. A dental amalgamator is used in the field of dentistry for the blending of restorative materials such as silver amalgam capsules and glass ionomer cement. This ensures a precise, controlled, and consistent mix.

The main components of an amalgamator are a series electric motor and a holder for receiving the capsule with the materials to be mixed for providing the filling compound. The typical amalgamator is designed to hold the ends of the capsule in a claw that is oscillating in a figure-of-eight pattern. The design accelerates the mixture towards each end of the capsule during each throw and impacts the mixture with the pestle. Amalgamators are used to forming amalgam fillings for treating cavities found in teeth.
