The invention relates to a composition for injectable cement, comprising a mineral sold phase, a separate liquid phase and, optionally, microparticles of a biocompatible and biodegradable polymer. The mineral solid phase comprises a mixture of powders with the molar composition: (CP)(CaO)(SrCO3), [CP being CaHPO2HO, CaHPO4, CaSrHPO, an equimolar mixture of bis(Ca(HPO), HO and CaO, or a mixture of two or three of said compounds] and y+z=4?1. The liquid phase comprises pure apyrogeneic water or a saline aqueous solution with pH 4 to 9. The ratio L/P [volume of liquid phase/mass of solid mineral phase] is at least 0.4 ml/g. The above is of application as bone replacement.

Composition for injectable cement useful as bone replacement

Phosphorus-calcium-strontium compound of formula (I); method for preparing same; composition for the extemporaneous preparation of a cement comprising a solid phase (SP) and a liquid phase (LP), wherein the solid phase comprises a mixture of inorganic compounds of formula (II); use as an endodontic cement.
