Abstract
The invention relates to implant materials that are based on hydraulic cements in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids and that react, when combined or when reacted with an aqueous liquid, to a solid in a cement-type initiation reaction. The invention also relates to the use of these materials as technical, medical-technical and/or pharmaceutical products, especially as bone cements, bone replacement materials, bone glues, dental filling materials and implantable active ingredient carriers. The implant materials according to the invention in the form of one or more pastes, suspensions or dispersions that contain mineral and/or organic and/or organomineral solids are formulated in an excipient liquid in such a manner that the pastes, suspensions or dispersions are stable in storage at normal conditions over a prolonged period of time and that they react, when combined with an aqueous liquid or when added to an aqueous liquid, in a cement-type initiation reaction and set to a solid. The excipient liquid of the mineral paste, suspension or dispersion is substantially water-free, and water immiscible …
