Abstract
A biomaterial composition for the resorption/substitution of organic supporting tissues, including 20-75 wt. % of an inorganic phase consisting of particles that include either hydroxyapatite (A) optionally mixed with tricalcium phosphate .beta. (B), or calcium-titaniumphosphate (Ca(Ti).sub.4 (PO.sub.4).sub.6) (C), and 80-25 wt. % of a liquid phase including an aqueous solution of a water-soluble biocompatible polymer that is cross-linkable under the effect of the pH of the medium. The composition is sterilizable, injectable and curable in biological media to form a biomaterial for replacing supporting tissues.
