Dimensionally Stable Molded Bone Replacement Element with Residual Hydraulic Activity

摘要

The invention relates to dimensionally stable molded bone replacement elements made of mineral bone cement with residual hydraulic activity that contain at least one share of hardened mineral bone cement and at least one share of unconverted or unhardened reactive mineral bone cement, wherein the share of hardened mineral bone cement is 5% to 90% by weight. The dimensionally stable molded bone replacement elements have at least 5% of the maximum value of the strength of a completely hardened bone cement comprised of the same mineral components and with the same structural characteristics and reach compressive strengths in the range of 2 to 200 MPa. They are substantially free of water and can be converted under biological conditions.

1. Dimensionally stable molded bone replacement elements made of mineral bone cement with residual hydraulic activity, containing
a. at least one share of hardened mineral bone cement, b. at least one share of unconverted or unhardened reactive mineral bone cement, characterized in that the dimensionally stable molded bone replacement elements have at least 5% of the maximum value of strength of a completely hardened bone cement made of the same mineral components and with the same structural characteristics, that the dimensionally stable molded bone replacement elements, which can be converted under biological conditions, 37° C. and water saturation, contain a share of hardened mineral bone cement of 5% to 90% by weight, that the dimensionally stable molded bone replacement elements have compressive strengths in the range of 2 to 200 MPa and that the dimensionally stable molded bone replacement elements are substantially free of water.
