    • The invention relates to a method for producing a bone cement with bioactivity and a corresponding bone cement kit. The method comprises mixing a monomer-free polymethylmethacrylate (PMMA) with a mass average molecular weight of 30,000 to 200,000 and an acid number of 10 to 350 mg KOH per g polymer in am amount of 5 to 13 wt. %, with a solvent for PMMA and 40 to 97 wt. % of at least one crystalline and/or glass-crystalline material is added to the mixture with the proviso that the crystalline or glass crystalline material contains 15 - 60 wt.% CaO, 30 - 50 wt.% P2O5, 0 - 9 wt.% ZrO2 and 0 - 3 wt.% fluoride and the mixing and stirring is carried out at a temperature of 10 to 500°C to give a free-flowing mixture with an open processing time in the range 1 to 20 minutes. The addition id preferably of 0.1-10 wt.% ZnO. The material is preferably used as cement or bone filler material in dentistry and as cement for kyphoplasty or vertebroplasty and as fixing cement for joint prostheses.
    • 本发明涉及一种骨水泥的与相应的生物活性和骨水泥试剂盒的制造方法。 该方法包括在一个事实,即不含单体的聚甲基丙烯酸甲酯(PMMA)可以与来自30000的重均分子量被混合至200,000和在按重量计的5-13%的酸值每克聚合物10至350毫克KOH的,与PMMA的溶剂 和按重量计混合40至97%,的至少一种结晶和/或玻璃 - 结晶材料被添加,条件结晶那和/或玻璃 - 结晶材料15 - 重量的CaO 60%,30 - 重量P2O5,0的50% - ZrO 2和0 9重量% - 3%的氟化物质量,并在搅拌下和在10至500℃的温度,直到可流动的混合物混合是一个开放的处理时间进行取值范围为1至20分钟。 加入的ZnO 0.1〜10%(重量)是有利的。 使用的材料的优选作为在牙科领域中的水泥或骨填充材料,以及用于椎体后凸成形术或水泥,以及定影水泥假体关节。
