The present concerns a solidifiable bone precursor composition which can be used to produce a mineralized substitute bone tissue material and the method of making the substitute bone tissue material. The substitute bone tissue material includes a collagen matrix comprising pores, and an apatitic mineral within the pores of general formula: As(TOx)t(QOx)uZy wherein A is a cation selected from Na, K, Mg, Ca, Fe3+, Al3+ or combinations thereof, T and Q are an anion oxide selected from P or C, Z is a H, OH or a halogen group, and s is 1 to 10, x is 2 to 4, t is 1 to 3, is 0 to 3 and y is 0 to 3. The solidifiable bone precursor composition includes: an aqueous dispersion comprising: at least one cation; and a polyphosphate combined to produce a cation-polyphosphate granule; and a collagen.
