To improve operativity, a pushing device for a tooth restoration material mixed and kneaded in a capsule comprises a compression coil springprovided between a leak preventive covercontacted with a capsule and having a cylindrical piston rodinserted, and a ratchet bodyhaving a rack partand fixed to the piston rod; a housing bodyhaving a supporting pathinserted in the leak preventive coverand a guiding pathprovided with the ratchet bodymovably; a ratchet body locking plate springfor preventing move of the ratchet body; a leverfor moving the rack partand returning the lever bodyto an initial position; a release bodyfor canceling the locking to the rack part; and a stopper meansfor stopping the ratchet bodyat the initial position.

Pushing device for tooth restoration material mixed and kneaded in capsule

A mixer for capsule for dental restoration material to mix a powder component and a liquid component within a mixing compartment of a capsule having an air-permeable filter without passing the powder and liquid components placed in a site connecting the inside of the mixing compartment to the outside into a mixture without air bubbles quietly, quickly and efficiently, includes a capsule holding compartment for holding the capsule such that the air within the mixing compartment can be discharged out from the air-permeable filter, a rotating unit of capsule holding compartment for subjecting the capsule holding compartment itself to a circular motion in the state that the longitudinal direction of the capsule holding compartment is kept in a constant direction, a driving unit for driving the rotating unit of capsule holding compartment, and a vacuum device connected to the capsule holding compartment.
