<P>PROBLEM TO BE SOLVED: To provide bone cement, restraining deterioration of cement strength which is caused by long-time use, and having excellent apatite forming capability. <P>SOLUTION: This bioactive bone cement composition includes: rutile type titanium dioxide particles and polymethacrylate polymers, wherein at least 15 wt.% rutile type titanium dioxide particles are contained to the total quantity of the rutile type titanium dioxide particles and the polymethacrylate polymers. In the bioactive bone cement composition, at least 15 wt.% rutile type as the titanium dioxide particles are mixed, so that the apatite forming capability in a pseudo body fluid is excellent. <P>COPYRIGHT: (C)2007,JPO&INPIT |
