Abstract: A capsule for dental restoration material capable of administering, immediately after mixing, a mixture substantially free of air bubbles to a patient site to be restored is disclosed. The capsule comprises a dental restoration material comprising two components of definite amounts of previously weighed powder component and liquid component accommodated in a cylindrical mixing compartment in an isolated state from each other, and an air-permeable filter that does not allow the powder component to exit the mixing compartment, but can ventilate air within the mixing compartment into the outside of the mixing compartment.

Abstract: There is provided a mixer for a capsule for dental restoration material used for mixing a powder component and a liquid component in a capsule accommodating therein the powder component and the liquid component for restoration of a tooth in the dental remedy field, by rendering a mixing compartment in vacuo so as to make it in a good state where the mixture does not substantially contain air bubbles.

Abstract: There is provided a capsule for dental restoration material, which can administer to a site to be restored of a patient with a mixture in a good state where air bubbles are not substantially contained, immediately after mixing. In the capsule for dental restoration material for directly administering to a restoration site of a tooth with the mixture prepared by subjecting a dental restoration material comprising two components of definite amounts of previously weighed powder component and liquid component accommodated in a cylindrical mixing compartment in an isolated state from each other to making the liquid component flow into the mixing compartment and mixing the both components, an air-permeable filter that does not pass the powder component therethrough but can ventilate air within the mixing compartment into the outside of the mixing compartment is placed in at least a part of a peripheral wall of the mixing compartment.

Abstract: 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.

Abstract: A capsule contains dental restoration material for applying directly to a site to be restored. A capsule main body has a mixing compartment for a powder component and a first aperture forming portion to form an outlet hole. A liquid cup has a compartment for a liquid component and a second aperture forming portion to form an outlet hole for the liquid component. A stopper is provided on an external surface near a rear end portion for inhibiting sliding of the cup into the main body while the second aperture forming portion is being broken through, but not inhibiting the cup to slide into the main body when a large force is applied. A plunger has a projection for breaking through the second and first aperture forming portions. A nozzle has a rear end portion with a shape corresponding to the tip portion of the main body.
