The present invention relates to methods for providing polymeric composites with bone forming, such as with osteogenic and/or osteoinductive and/or osteoconductive, properties. The present invention further relates to polymeric composites provided by the present method and the use of thereof for bone implants, or grafts, specifically the use thereof for orbital floor reconstruction. Specifically, the present invention relates to methods for providing a composite with bone forming properties, the method comprises the steps of: a) providing a liquid, or liquefied, polymeric composition of homopolymers or copolymers of 1,3-trimethylene carbonate (TMC); b) adding to said liquid, or liquefied, polymeric composition one or more agents with osteogenic and/or osteoinductive and/or osteoconductive properties thereby providing a dispersion of said agents in said liquid or liquefied polymeric composition; and c) crosslinking the product obtained, thereby providing a composite with bone forming properties.

A discovery of the conversion of amorphous calcium polyphosphate (ACPP) or/and other polyphosphate salts with various type of calcium phosphate to new calcium phosphate product (i.e. dicalcium phosphate dihydrate (DCPD)) in a liquid environment. The discovery includes mixing a various type of calcium phosphate with an aqueous ACPP or/and other polyphosphate salts gel, which is fast setting and possessing strong mechanical strength, and can be gradually converted to DCPD/hydroxyapatites in physiological condition. This injectable past can be applied as alternative of conventional CPC bone cement that is suitable for bone void repair due to its excellent properties in osteoconductivity and osseointegration. It can also be applied as drug delivery device in tissue engineering for its strong bonding to drug molecules.

Sliceable bone repair material is a porous block-shaped scaffold containing a hydrogel, wherein the hydrogel is formed by Michael type addition of at least two precursor molecules. Said scaffold is made of a synthetic ceramic material and has interconnected macropores having a diameter above 100 m. In addition said scaffold has a total porosity of 60 to 80%. The total volume of the hydrogel is smaller than the total volume of the interconnected macropores.

A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

The present invention is directed to a novel cement powder comprising an organic component consisting of one or more biocompatible and bioresorbable polymers and an inorganic component consisting of one or more calcium phosphate compounds. The invention also relates to the apatitic CPC resulting from the mixing of said cement powder with a liquid phase and setting.
