Description

A kind of CaO-P 2O 5-Na 2O-TiO 2-ZrO 2Biological glass ceramic and preparation method thereof
Technical field:
The present invention relates to the glass ceramics field, particularly relate to the CaO-P that clinical medicine is used with high strength and high bioactivity 2O 5-Na 2O-TiO 2-ZrO 2Biological glass ceramic and preparation method thereof.
Background technology:
Human body hard tissue reparation and reconstruction biomaterials be in the biomedical material development the earliest, the most sophisticated field.Up to now, the material that is used for hard tissue repair and replacement has skeleton derivant of Metal and Alloy, biological glass ceramic, polymer, composite and humans and animals etc., document [1]: Yu Yaoting sees reference. bio-medical material. and Tianjin: publishing house of University Of Tianjin, 2000:116.Biological active glass ceramic be a class can with the biomaterial of biologic soft tissue or osseous tissue bonding, have the incomparable advantage of metal, macromolecule and bio-inert material.Therefore, people have produced keen interest to this class new material, and develop multiple biological active glass ceramic, for example:
Figure C20051004728300031
Bio-vitric (Na 2O-CaO-SiO 2-P 2O 5System), Ceravital devitrified glass (Na 2O-K 2O-MgO-CaO-P 2O5-SiO 2System), A-W biological glass ceramic (MgO-CaO-SiO 2-P 2O 5System), (HA consists of the hydroxyapatite bioactive pottery: Ca 10(PO 4) 6(OH) 2) or the like, the document that sees reference [2] and [3], list of references [2]: Larry L.Hench.Bioceramics.J.Am.Ceram.Soc.1998,81[7]: 1705-1728; List of references [3]: Yang Weizhong, Zhou Dali, Yin Guangfu and Zheng Changqiong. the magazine .2003 of biomedical engineering, 20 (3): 541-545.Compare with other bio-inert material, biological glass ceramic has better biocompatibility, higher bone bond strength and osteogenic ability faster, the document that sees reference [4]: Li Yubao. biomedical material. and Beijing: Chemical Industry Press, 2003:82.But most of bioactivity glass all contain a large amount of SiO 2And Nagase et al. finds mouse death when experiment mouse lumbar injection contains the normal saline of titanium dioxide silico-calcium phosphorus glass, then do not show toxicity when not containing silicon dioxide, document [5] sees reference: Nagase M, Abe Y, Chigira M and Udagawa E.Toxicity of silica-containing calciumposphate glasses demonstrated in mice.Biomaterials.1992,13:172-175.
Biological glass ceramic is finished by bone conduction passage as bone alternate material clinically.Because its excellent biological compatibility does not cause significant reaction behind the implanting to human body, host's callus can be converged by the face of creeping around the implant, and with the implant parcel, makes it to play the filling effect damaged with being connected bone.But its lower toughness has limited applying of it.Zirconia ceramics is a kind of very important structural ceramics that is only second to aluminium oxide that newly-developed gets up.Because its superperformance, thereby more and more is subject to people's attention the document that sees reference [6]: Liu Weiliang as high rigidity, high strength and higher fracture toughness. advanced ceramics technology. Wuhan: the .2004:176-180 of publishing house of Wuhan University of Technology.Zirconium oxide joins in the glass ceramics as the nucleus agent very early.In the glass composition, add the zirconium oxide microgranule, can make glass fracture strength bring up to 3MPa from 2MPa, document [7] sees reference: Tang Jiwen, Zhang Yude and Liu Chunmei. the progress of bio-active devitroceram artificial material. and Shandong medicine .1997,37[5]: 45-50.CaO-P 2O 5Series vitro-ceramic is a kind of new bio glass ceramics that newly-developed gets up, this be the pottery composition and body bone tissue approaching, has good biological activity and nontoxic, document [8] sees reference: Kasuga T and Abe Y.Calcium phosphate invert glasses with soda andtitania.J.Non-cryst.Solids.1999,243:70-74.The present invention is at CaO-P 2O 5On the series vitro-ceramic basis, introduce ZrO 2, form CaO-P 2O 5-Na 2O-TiO 2-ZrO 2Series vitro-ceramic.It is a kind of SiO that do not contain 2Bio-vitric, have higher Ca/P than and the composition similar with human body hard tissue, have higher fracture strength and biological activity, be more suitable for doing the human body embedded material.
