Abstract
The invention relates to composite materials based on polysilicic acid, said materials containing novel compositions which have improved material properties and can be in the form of dispersions, pastes, powders, granulated materials, layers or compact moulded bodies. The aim of the invention is to produce composite materials based on polysilicic acid with improved mechanical properties. To this end, the composite materials contain polysilicic acid, between 0.01 and 20 mass % of an organic polymer, more than 15 mass % of at least one calcium phosphate phase, and optionally a use-specific additive. The material produced according to the invention can be implanted or injected. The composition of the composite material with the resulting properties enables the composite material to be used for bone substitution and/or bone regeneration in both human medicine and animal medicine. The inventive material can also be used to heal wounds.
