| description | FIELD: medicine, osteoplasty. ^ SUBSTANCE: invention relates to cement materials used in plastic reconstruction of damaged osseous tissues. Composition material is prepared on basis of reaction-hardening mixture of the following powders: hydroxyapatite, tricalcium phosphate, tetracalcium phosphate and titanium powder as an additive. As a mixing liquid method involves using solution of magnesium, potassium and/or sodium phosphates, phosphoric acid and water wherein components are taken in the definite ratio. Strength carcass is formed in the hardening process of the material showing uniform distribution of titanium particles that promote to enhancing strength and crack-resistance. High mechanical indices and availability of the parent materials provide broad using this material for closing cavities in osseous tissues, among them complex-loaded ones. ^ EFFECT: improved and valuable properties of material. ^ 1 tbl, 1 ex |
