BRUSCHITE CEMENT FOR ORTHOPAEDIC SURGERY Russian patent published in 2013 - IPC A61L24/02 A61L27/10 A61L27/12 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, and may be used for facialmaxillary osseous prosthesis, as a drug delivery system and as a matrix for tissue engineering structures. Bruschite cement contains (wt %): β-tricalcium phosphate - 34.5-45, monocalcium phosphate monohydrate - 23-29.5, bioactive glass - 0.5-10, water-base tempering fluid 25-32.5. The bioactive glasses are strongly alkaline glasses as follows (wt %): SiO₂-40-60, CaO-10-25, Na₂O-22-35, P₂O₅-3-5, of insular, chain, ring or layer silica-oxygen motifs. The glasses are introduced in the amorphous or crystalline state at the granule dispersity 30 to 80 and 80 to 120 mcm.

EFFECT: allows adjusting the dig structure of the material, its mechanical properties, pH and solubility in the buffer solutions, as well as enables intensifying the regenerative processes in the injured osseous structures and reducing the length of treatment and recovery of the bone integrity.
