    摘要: Foam-generating, hardening composition for making impressions of biological surfaces include A at least one impression material based on i isocyanates, which react with mono- and multi-functional amines and/or compounds having hydroxyl groups, to form urethane or urea, or ii A-silicones, or iii C-silicones, or iv Polyethers, or v alpha-silanes, or vi mixtures of two or more materials i to v, and optionally B at least one foaming agent. Impressions of biological surfaces made from this compound have a foam with closed pores.

    摘要: Single-use cartridges for the storing and dispensing of dental two-component impression materials have a closable external chamber with a cylinder-shaped external wall, a cylindrical closable internal chamber that is arranged coaxially or eccentric therein, a mixing element including housing and mobile mixer that is to be mounted separately or connected firmly to the external chamber at its inlet end. Either the internal cylindrical chamber is arranged such that it can be rotated and forms the drive shaft for the mobile mixer part of the mixing element, or the drive shaft extends parallel to the central axis through the internal cylindrical chamber or forms the central axis. The content of the chambers can be dispensed by means of conveying means whose axial thrust motions can be controlled independent of each other.
