摘要:
A dental powder/liquid material-containing preparation accommodation bag, which suppresses entrainment of air in mixing a powder material and a liquid material for dispensing, is provided. A powder material 8 is accommodated in a powder material accommodation chamber 3 of a bag body 2, while a liquid material 9 dissolving the powder material 8 and changing into a pasty form in cooperation with the powder material 8 is accommodated in a liquid material accommodation chamber 4 partitioned from the powder material accommodation chamber 3 by a weakened section 7. The weakened section 7 is ruptured by applying a pressing force to the bag body 2. As a result, the powder material accommodation chamber 3 and the liquid material accommodation chamber 4 communicate, to feed the liquid material accommodated in the liquid material accommodation chamber 4 into the powder material accommodation chamber 3. Then, the powder material 8 and the liquid material 9 changing into the pasty form are pressed within the powder material accommodation chamber 3 from the surfaces of the bag body 2 for dispensing.

The invention relates to a mixing device comprising a mixing base on which consituents of a material to be kept damp, especially a ceramic material, are mixed. Said mixing device also comprises a liquid container and dampening means that are connected to the liquid container and are arranged and embodied in such a way as to keep damp the constituents of the material to be kept damp. The dampening means comprise a long liquid carrier which ensures the transport of liquid in the longitudinal direction thereof and provides a supply of liquid over the surface thereof, perpendicularly to the longitudinal direction, for constituents to be kept damp. Said liquid carrier is connected to the liquid container, and is adjacent to a mixing surface of the mixing base.

The present invention is related to a device for providing a dental material. The device comprises first and second compartments formed between sheet-like layers, and first and second dispensing outlets for the first and second compartments, respectively. For use, the device can be positioned with the compartments overlapping each other and with the dispensing outlets located side by side. The invention may provide a rather inexpensive device which may help a user in a convenient preparation of a dental material.

The present invention is directed to a package assembly for placing it on a surface and for storing and/or delivering substances, preferably dental substances, comprising:
at least one container with at least one base and at least one lid; and at least one hinge connecting the base and the lid; wherein the base and the lid comprise at least a first and second lever; the first and second levers are provided at the container essentially on the side of the hinge and; a projection of the first lever onto the surface and the second lever extend with their free ends essentially in a direction away from the hinge; and wherein the container can be opened or the lid can be removed from the base by moving the ends of the first and second lever relative to each other. The invention is further directed to a method for providing dental substances, a kit with an assembly, as well as the use of an assembly and a method for storing and/or delivering dental substances.

The present invention relates to a device for storing and dispensing a flowable substance. The device comprises a container comprising a base member and a cover member being sealingly connected with each other along the circumference of the container, a compartment for receiving the substance, and an open ended pocket area into which the substance is transferable from the compartment, and a cannula having an internal passageway being in fluid communication with the pocket for dispensing the substance.

The invention relates to a method for producing crowns etc. by producing a frame, for example, made of alumina, whereby a film (6) is shrink-fitted on the die (3) of a working model. The film (6) is provided with a slip and the slip is baked on a frame after the film is removed. In order to accelerate the method and to avoid the loss of materials, the die (3) is placed on a rotatable shaft (2). The slip is deposited with a tool (5). A drying process using a hot air dryer (7) is carried out during and/or after depositing the slip. This method can also be carried out in a CNC machine with which the veneer ceramic is successively deposited. A separating agent similar to lipstick can be deposited in place of the film (6). Said separating agent melts at temperatures greater than 45 °C when the spacer function is not used. The invention also relates to a crease-free shrink-fitting of the film (6). In addition, the invention shows how the infiltration itself can result in the ceramic furnace, whereby the frame lies on a base which absorbs the excess glass. The invention also relates to a dosing device for slip with which the slip is to be dosed on the shrink-fitted film in a uniform consistency.

A method and kit is presented, wherein a prepared tooth cavity is etched; treated with a primer/adhesive which is cured; treated with a flowable composite and cured; and then filled with a condensable composite, using techniques and instruments developed for use with amalgams. Such techniques include transferring the composite with an amalgam carrier, and shaping and packing the composite with an amalgam plugger. The dental restoration may optionally be further etched and sealed. The kit comprises at least a condensable composite and an amalgam carrier. The condensable composite is further provided in premeasured amounts, that is, in amounts of one spill, two spills, or three spills. In another embodiment, the kit further comprises a flowable composite material, and in still another embodiment, the kit further comprises a flowable composite material and dispenser, an etchant, a primer/adhesive, a plugger, and brush tips. The kit is especially useful in forming posterior dental restorations that are aesthetic, strongly-bonded, and wear-resistant. The restorations have negligible shrinkage upon polymerization.
