Abstract: A dispensing device for fluid substances includes a receiving element for receiving fluid substances, formed of at least two rigidly interconnected containers with adjacent outlets on the front sides thereof, a mixing nozzle which is connected to the receiving element by a mixing nozzle holder and which is fluidically and conductively connected to the outlets, and a pressure-producing device for ejecting the fluid substances through the outlets. The mixing nozzle holder is a detachable catching closure.

Abstract: The invention relates to a kit of parts consisting of: a) a material for producing a shaped body; b) a metal powder, a powder of a metal alloy, a powder of a pigment having a metallic effect or a powder having a laminar structure, and; c) if needed, of customary additives. The inventive kit of parts can be used to produce shaped bodies, especially in the field of dentistry, which can be excellently detected by optical systems.

Abstract: The invention relates to “tooth-bleaching agent” compositions and to their applications in whitening teeth. The dental bleaching agent of the present invention comprises apatite, especially preferably in particle sizes in the nano range, likewise especially preferably in the form of fluorapatite. The tooth-bleaching agent can have a desensitising action and a positive action in respect of the remineralisation of the tooth surface.

Abstract: The invention relates to a disposable packaging system (2) for storing and dispensing multi-component materials (6), wherein the disposable packaging system (2) has a rigid housing (5) which is separated by films (8) into at least two regions for storing and mixing multi-component materials (6), and wherein the films (8) are arranged as separating membranes (9) in the housing (5) and have weak points (10) which tear open on contact with a sharp object (11) so that the materials (12, 13) separated by the separating membranes (9) mix together in the housing (5).

Abstract: The invention relates to mixtures comprising polymers containing hydrogen-siloxane groups and fluoride, in addition to the use of said mixtures as a dental scaling varnish and fluoridation varnish and as a desensitising agent, in addition to the use of said mixtures as a protective covering for glasionomer cement fillings.

Abstract: A visible light photopolymerizable composition comprising a) an aryliodonium salt and b) an acylphosphine oxide compound. These compositions can be used together with an epoxy resin as a dental composition.

Abstract: The invention relates to copolymers, obtained by the copolymerisation of SiH-group-containing siloxanes with vinyl-group-containing compounds. The copolymers comprise at least two SiH groups. The SiH-groups-containing siloxanes and the vinyl-group-containing compounds are linked to one another via C—Si bonds.

Abstract: This invention relates to the kit of parts containing (co)polymers having hydrogen-siloxane groups, a catalyst, a vinyl compound and a hydrosilyl compound. The kits of parts may be used as permanent or temporary, soft or hard elastic, bonding or filling materials on a dental substrate or a bone substrate.

Abstract: A visible light photopolymerizable composition comprising a) an aryliodonium salt and b) a titanocene derivate. These compositions can be used together with an epoxide resin as a dental composition.

Abstract: The present invention relates to a kit of parts, comprising at least one partially resoluble (co) polymer, at least one adhesive for silicones, optionally a base body, and optionally a silicone composition. Moreover, the invention is the use of parts in a kit for the manufacture of an impression tray.

Abstract: The present invention relates to a molding that has a layer of copolymers that are crosslinkable by means of addition or condensation reactions and, optionally, thereon, a layer of silicone that is crosslinkable by means of addition or condensation reactions.
