摘要:
Provided is a cartridge assembly comprising a cartridge for containing a dental substance. The cartridge comprises a dispensing opening for the dental substance. Further the cartridge assembly comprises a piston having a receptacle for establishing a screw connection with a spindle for moving the piston for dispensing the dental substance. This assembly helps minimize costs in the manufacturing and use of dental cartridges and/or dental dispensing devices.

A device for dispensing a dental composition is provided. The device has a plunger for extruding dental composition from a container, an energy accumulator for advancing the plunger, and an actuator for charging the energy accumulator. The force for actuating the actuator is lower than the force at which the plunger can be advanced. The device preferably provides convenient dispensation of dental compositions.

A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.

The invention relates to a device comprising a mixer tube (2), whose diameter diminishes toward one end, a mixer helix (5), which is located inside the mixer tube (2), and comprising a plunger (6,7). According to the invention, the mixer helix can or should be accordingly compressed inside the mixer tube with the aid of the plunger that is inserted into the mixer tube. The device enables a largely complete dispensing of the material remaining in a static mixer helix during mixing and is suited, above all, for storing, mixing and dispensing dental materials.

The invention relates to an apparatus for generating a multi-component compound, in particular for dental purposes, comprising: —At least two cartridges (3), each cartridge (3) adapted for containing a component (4) of the multi-component compound and having a plunger (2) adapted for pressing out its component (4) from the cartridge (3); and—a driving device for said plungers (2) in which the driving speed is adjustable, wherein the driving device comprises a stepping motor (1), and a detector associated with the stepping motor for detecting at least one of a) the steps of the stepping motor and b) The load on the stepping motor. At low revolutions per minute, the stepping motor (1) offers higher torque as compared with the known DC motors, whereas it also offers high revolutions per minute, although with comparatively low torque, sufficient for rapid advance and retraction of the plungers (2).

The invention features a composition which can or is to be used in a dental retraction, the composition comprising liquid a liquid and a layer type 1:1 silicate mineral and a layer type 2:1 silicate mineral in a ratio from about 50/50 to 5/95 wt.-% with respect to each other. The invention also relates to a container containing the dental retraction composition and to a kit comprising parts A and B, wherein part A comprises the dental retraction composition and part B comprises at least one accessory selected from the group of applier, dental impression material, retraction cap(s), a container for storing and dispensing the composition and combinations thereof. The invention further features a process of dispensing a dental retraction composition, the process comprising the steps: providing a dental retraction composition contained in a container, placing the container in an applier, and using the applier for dispensing the dental retraction composition out of the container.
