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.
