Abstract: The invention relates to a cartridge having at least one tube (3a, 3b), particularly a circular cylindrical tube. At least one outlet opening (11a, 11b) is provided in the side wall of the tube. Furthermore, a closure piston (10a, 10b) and a dispensing piston (4a, 4b) that can be adjusted by means of a piston rod are disposed, in sealing and displaceable manner, spaced apart from one another in such a manner that a chamber for accommodating substances that are capable of flow and/or pasty substances is formed between the closure piston and the dispensing piston (4a, 4b).

Abstract: A method for sterilizing medical single-component or multi-component impression materials that can harden, and a two-component impression material. In a first step of the method, the components of the impression materials that have not hardened are introduced into a primary packaging. In a second step, the primary packagings, with the components contained therein, are sterilized by heat sterilization. In a third step, the sterilized components in the primary packagings are introduced into a secondary packaging. In a fourth step, this secondary packaging is sterilized by means of a suitable gas sterilization, irradiation sterilization, and/or by means of sterilization in an autoclave, so that the activity and the viscosity of the components are not changed.

The softening temperature of the thermoplastic film (4) ranges between approximately 40 DEG C. and approximately 80 DEG C.

Abstract: A photopolymerizable single-component dental material, that is useful as a temporary, photopolymerizable single-component crown and bridge material. The material contains at least one compound that can be polymerized by means of photoinitiation, at least one photoinitiator, and filler, if necessary.

Abstract: A set or assembly for producing at least one temporary crown or bridge material has a carrier for accommodating a crown and bridge material and a crown and bridge material in an amount that is at least sufficient for the production of a tooth crown. The crown and bridge material is a light-curing and, in particular, flowable single-component material, and the carrier that can be adapted to the tooth situation is transparent or translucent. In another aspect, a method for producing a temporary tooth crown or bridge and a temporary tooth crown or bridge produced by the method are also provided.

Abstract: A device for storing and dispensing fluid substances has at least one container having at least two cartridges for accommodating fluid substances. The container is provided with at least two outlet nozzles on its face, to which a dispensing element can be releasably locked by way of at least one spring segment. Particularly simple operation of the device and a secure hold of the dispensing element can be achieved in that a locking element is associated with the at least one spring segment. The locking element is movable relative to the at least one spring segment and can be moved from a first, open position in which the at least one spring segment is released, into a second, locking position in which the spring segment is brought into engagement with the dispensing element to lock it.
