Abstract: The present invention relates to a kit of parts comprising Paste (A), Paste (B) and Paste (C), the pastes being characterized as follows: Paste (A) comprising at least one polyorganosiloxane with at least two olefinically unsaturated groups, and at least one organohydrogenpolysiloxane, at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s); Paste (B) comprising at least one polyorganosiloxane optionally with olefinically unsaturated groups, at least one addition cure catalyst, optionally at least one alkylsiloxane having at least one carbinol, silanol, alkoxy, carboxyl or amino group, optionally filler(s) and optionally additive(s) Paste (C) comprising a softener, a condensation cure catalyst, optionally filler(s), and optionally additive(s) optionally at least one polyorganosiloxane optionally with olefinically unsaturated groups. The invention is also directed to a system for storing and delivering Paste (A), Paste (B) and Paste (C), the system comprising three compartments for storing the respective pastes, means for delivering the respective pastes to an outlet orifice and an interface for receiving a mixing tip. The kit of parts or the system is in particular useful for conducting a dental retraction and dental impression process.

Abstract: A device for dispensing a dental material has a cartridge and a ball-shaped closure member. The cartridge and the closure member in combination form a rotary slide valve for selectively opening and closing a cartridge outlet for the dental material, such that the device can be operated between an operative position in which the cartridge outlet is open and a storage position in which the cartridge outlet is closed. The device further has a cannula which is removably receivable within the closure member. The cannula in the operative position of the device is mechanically locked against removal. The cannula further has an annular seal which in the operative position extends into the outlet.
