Abstract: A dental handpiece comprising a power source, plugger means, and a disposable cartridge assembly removably engagable with the power source, said plugger means being carried by the power source and selectively movable with respect to the cartridge for passing therethrough in a reciprocal movement, said cartridge including a housing preloaded with selected quantities of mercury and silver, or the like, in separate sealed compartments, and means extending through the housing and engagable with the power source for longitudinal and rotatable movement with respect to the housing, said longitudinal movement causing a combining of the initially separated mercury and silver components, said rotatable movement causing both mixing of the components to produce amalgam for denture fillings and discharging of said amalgam from the housing for engagement thereof by the plugger means, and said plugger means being selectively reciprocal through the cartridge for implanting multiple charges of the amalgam in a tooth cavity, o

Abstract: A disposable cartridge or capsule for storing at least two independent ingredients preloaded therein in mutually sealed relationship, and selectively combining and mixing the ingredients to provide a substantially homogeneous compound. The cartridge comprises a sectional housing having mixer means rotatably mounted therein, said mixer means being carried by sealing means which cooperates with the housing for providing at least two sealed compartments therein in one position of the sealing means and opening communication between the compartments in a second position of the sealing means. Subsequent to a mixing operation, one of said housing sections may be separated from the other housing section and released from engagement with the sealing means and mixing means whereby the mixture may be stored in said removed housing section for use.
