摘要:
A method for producing a bioactive bone cement and a bone cement kit for anchoring artificial joints and for filling out bone defects. The method avoids polymerization-linked by-products and disadvantageous effects, while at the same time providing the bone cement with long-term stability. The inventive method uses a monomer-free polymethylmethacrylate, which is mixed with a suitable non-toxic solvent, and a bioactive, vitreous-crystalline material with a particle size ranging from >20 to 200 μm, having 15–45 wt. % CaO, 40–45 wt. % P2O5, 10–40 wt. % ZrO2 and 0.7–3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to a bone cement kit having said components.
