Bioactive organic-inorganic composite prepared by mechanochemical method

A bioactive sol-gel derived powder/PEEK(TM) composite was prepared by combination of mechanochemical and hot press method for the repairing of bone defects. After milling for 30mins., fine-grained bioactive powder was well dispersed on the surface of the PEEK(TM) powder. It was also shown that the novel composite formed bonelike apatite on its surface after soaking into simulated body Fluid for 2 weeks. This result indicates that the composite bone to living bone when implanted into bone defects. From the results, it was suggested that combination of mechanochemical and hot press method is effective technique for fabricating bioactive organic/inorganic composite for repairing of bone defects.
