Abstract: A dynamic mixer, useful for mixing components of viscous compounds, in particular for components of dental impression compounds, and use thereof, the mixer having a mixing tube that contains a drivable rotor and that has on one end an end wall having at least two inlet openings for components, and at the other end an outlet opening for the mixture thereof. The rotor has a rotor disk having at least one entraining element that faces the end wall, and at least one rotor disk opening for the components to pass through to the side of the rotor disk that is remote from the end wall. At least one mixing element is arranged on the rotor hub between the rotor disk and the outlet opening. At least one projecting pin is arranged on the end wall toward the rotor disk, and the at least one entraining element has at least one recess for the at least one pin.

Abstract: The invention relates to a dynamic mixer (1) for viscous masses, in particular for components of dental impression masses, and to the use of said dynamic mixer for dental impression masses.

Abstract: A device for storing and applying a dental substance, with a container from which the substance can be removed through a first opening in a first direction with the aid of an applicator, and with a substance supply which can be introduced into the container through a second opening in the wall of the container and which is sealed off against this opening by a breakable foil, is characterized in that the second opening is arranged transversely with respect to the first direction and that the foil is applied over the opening in such a manner that it closes same.

Abstract: An applicator for dental compounds includes a shaft, the front end of which can be connected with the aid of a fastening device to a syringe containing the dental compound, and a plunger. The shaft contains a ram for advancing the plunger. The fastening device has an inner sleeve, attached to the shaft, and an outer sleeve, attached on the inner sleeve rotatably with respect to it. The inner sleeve is substantially cylindrical and has such a cavity that its cross section is substantially U-shaped. Clamping takes place as a result of eccentricity.
