Prepared phase stable and sedimentation, plastically deformable, with intrinsic pore formation, intended, for example, for filling bone defects or for use as a bone substitute material, and method for its production.

摘要

A prepared paste-like, plastically deformable, for construction / bone replacement, based on suspensions of ceramic material may be applied using an injection cannula, comprising a particulate component, porous, which is not readily soluble in water, and at least one liquid component, waxy or gel which is dissolved in water or alcohol, wherein the particulate component is not readily soluble in water is calcium phosphate and / or a bioactive glass ceramic material; the liquid component, waxy or gel which is soluble in water is an aqueous or alcoholic solution of an organic binder selected from the group of alginates, starches, polysaccharides, celluloses, modified celluloses, hyaluronic acids and their salts, gelatins, collagens , shellac, polyacrylic acids, aqueous or alcoholic solutions thereof, dextrans, polyethylene glycols, or mixtures thereof; the component is not readily soluble in water is 60-98% by weight, and the component dissolved in water or alcohol is 1-30% by weight, wherein the particles of component particles having a diameter in a range of sizes is substantially greater than a and smaller particle fagocitable the pitch diameter cannulas standard injection and the portion of the component dissolved in water or alcohol is 0.1-3% by weight, wherein the particles have a size in the range of 0.1 to 150 microns, pores in the range 0.01-50 microns and a polygonal shape with a rounded broken sintered structure.
