Resumen
There are evidences considering the effectiveness of Si on enhancing biological properties of calcium phosphates; however, there are not many works relating to the Si-alpha-TCP bone cement. The influence of silicon doping on the properties of α-TCP cement was analyzed. Si-TCP was obtained by a solid state reaction employing CaCO 3, CaHPO 4 and CaSiO 3 and powder was analyzed by XRD, FTIR, XRF and BET specific area. Cement samples were analyzed for their surface of fracture morphology, mechanical resistance and SBF bioactivity. Cement mechanical resistance was not satisfactory for biomedical application; nonetheless, sample's surface was coated by an apatite layer after immersion in SBF. Notwithstanding, to ensure that silicon is the element responsible for increasing the material's bioactivity it is necessary to evaluate the in vivo performance of the bone cement obtained in this work. 14 4 493 498 Wei, X., Ozan, U., Ankit, A., Acar, H.Y., Akinc, M., Dissolution behavior of Si, Zn-codoped tricalcium phosphate (2009) Materials Science and Engineering C, 29 (1), pp. 126-135. , http://dx.doi.org/10.1016/j.msec.2008.05.020 Matsumoto, N., Yoshida, K., Hashimoto, K., Toda, Y., Thermal stability of β-tricalcium phospahte doped with monovalent metal ions (2009) Materials Research Bulletin, 44 (9), pp. 1889-1894. , http://dx.doi.org/10.1016/j.materresbull.2009.05.012 Li, X., Ito, A., Sogo, Y., Wang, X., Le Geros, R.Z., Solubility of Mg-containing β-tricalcium phosphate at 25°C (2009) Acta Biomaterialia, 5 (1), pp. 508-517. , http://dx.doi.org/10.1016/j.actbio.2008.06.010 Pietak, A.M., Reid, J.W., Stott, M.J., Sayer, M., Silicon substitution in the calcium phosphate bioceramics (2007) Biomaterials, 28 (28), pp. 4023-4032. , DOI 10.1016/j.biomaterials.2007.05.003, PII S014296120700381X Arcos, D., Sanchez-Salcedo, S., Izquierdo-Barba, I., Ruiz, L., Gonzalez-Calbet, J., Vallet-Regi, M., Crystallochemistry, textural properties, and in vitro biocompatibility of different silicon-doped calcium phosphates (2006) Journal of Biomedical Materials Research - Part A, 78 (4), pp. 762-771. , DOI 10.1002/jbm.a.30790 Camiré, C.L., Saint-Jean, S.J., McCarthy, I., Mochales-Palau, C., Lidgren, L., Planell, J.A., Production methodology and reactivity of silica substituted α phase tricalcium phosphate (2004) Proceedings Ofth 7th World Biomaterials Congress, , Sydney, Australia.
