ABSTRACT:
Apparatus for the delivery of light-curable composite dental filling material comprises a tubular composite reservoir, plunger and slider. The slider is free to move longitudinally along the reservoir but is matingly mounted to facets on the outside surface of the reservoir to prevent angular movement of the slider relative to the reservoir. The plunger consists of a shaft threaded to mate with the threaded inside diameter of the composite reservoir. The plunger also has a disk integrally formed to end of the shaft at one end and a male front piece at the other. The male front piece mates with a female fitting of a separate composite extrusion element.
