Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a syringe for storage, mixing and dispensing of multi-component paste materials, and more precisely to a syringe for two or more components of a paste material which are to be mixed together. The syringe may be activated so that the chambers containing the components are opened, and the components may be mixed together and extruded through a mixing tip.

Abstract: A device for dispensing a dental composition is provided. The device comprises 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.

Abstract: A capsule for storage, mixing, and dispensing of dental material, including an indicator for indicating proper activation of the capsule. The indicator may indicate that a minimum required displacement of an applicator member or of an activator member, or both, has occurred.

Abstract: 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.

Abstract: The invention includes a piston having a piston body (1) and front seal for sealing the gap between the side wall of the piston body and the wall of a chamber within which the piston and a material are disposed in a conventional manner. The front seal (5) has a leading edge (6) included angle (A) as defined below, and a trailing edge (7) included angle (B) that is smaller than the leading edge included angle. By the appropriate selection of these two angles, the force required to move the piston (and thus the material) is optimized, the force required to move the piston (and thus the material) is optimized, which results in a more useful dispenser than conventional syringe-type dispensers. These and other features of the present invention are described in greater detail below.

Abstract: The invention relates to a dynamic mixer for mixing at least two paste components of different volume proportions. Said mixer comprises a housing with at least two inlet openings and at least one outlet opening, a mixer element being rotatably mounted in a mixing chamber of said housing. The housing has at least one delay chamber comprising a limiting wall that blocks the paste stream in the direction of flow and at least one opening that opens into the mixing chamber, said opening(s) being set back in relation to the limiting wall. The mixer is particularly suitable for mixing paste components with a relatively high viscosity of, for example, greater than 800 Pas.

Abstract: The invention relates to a dental retraction device to be used for retracting the gingiva from a prepared tooth structure, the retraction device having the shape of a cord with a radial (x- and y-direction) and longitudinal direction (z-direction) and comprising an absorbing agent and optionally a retarding agent, wherein the retraction device is able to expand in the radial direction (x- and/or y-direction), but essentially does not expand in the longitudinal direction (z-direction) upon contact with fluid.

Abstract: The present invention is directed to a unit dose delivery system for flowable substances. The delivery system or applicator of the present invention allows storage, mixing and well controlled dispensing of multi-material component substances.

Abstract: The present invention is directed to a system for storing and dispensing a substance and a method for air free filling of the same. The system comprises at least one compartment for storing a predetermined amount of a substance, wherein said compartment has a back end and a front end for filling and dispensing the substance, respectively. The system further comprises a vent, a movable front plug and a displaceable piston for sealing the compartment at the back end, wherein the compartment defines a predetermined volume between the vent and the movable front plug within the compartment downstream of said piston.
