Resumen
PURPOSE: To investigate the osseointegration properties of prototyped implants with tridimensionally interconnected pores made of the Ti6Al4V alloy and the influence of a thin calcium phosphate coating.METHODS: Bilateral critical size calvarial defects were created in thirty Wistar rats and filled with coated and uncoated implants in a randomized fashion. The animals were kept for 15, 45 and 90 days. Implant mechanical integration was evaluated with a push-out test. Bone-implant interface was analyzed using scanning electron microscopy.RESULTS: The maximum force to produce initial displacement of the implants increased during the study period, reaching values around 100N for both types of implants. Intimate contact between bone and implant was present, with progressive bone growth into the pores. No significant differences were seen between coated and uncoated implants.CONCLUSION: Adequate osseointegration can be achieved in calvarial reconstructions using prototyped Ti6Al4V Implants with the described characteristics of surface and porosity. 29 9 579 587 Sanan, A., Haines, S.J., Repairing holes in the head: A history of cranioplasty (1997) Neurosurgery, 40 (3), pp. 588-603. , Mar, PMID: 9055300 Bandyopadhyay, A., Espana, F., Balla, V.K., Bose, S., Ohgami, Y., Davies, N.M., Influence of porosity on mechanical properties and in vivo response of Ti6Al4V implants (2010) Acta Biomater, 6 (4), pp. 1640-1648. , May Vehof, J.W.M., Haus, M.T.U., De Ruijter, A.E., Spauwen, P.H.M., Jansen, J.A., Bone formation in transforming growth factor beta-I-loaded titanium fiber mesh implants (2002) Clin Oral Implants Res, 13 (1), pp. 94-102. , Mar Ponader, S., Von Wilmowsky, C., Widenmayer, M., Lutz, R., Heinl, P., Körner, C., Singer, R.F., Schlegel, K.A., In vivo performance of selective electron beam-melted Ti-6Al-4V structures (2010) J Biomed Mater Res A, 92 (1), pp. 56-62. , Jan Warnke, P.H., Douglas, T., Wollny, P., Sherry, E., Steiner, M., Galonska, S., Becker, S.T., Sivananthan, S., Rapid prototyping: Porous titanium alloy scaffolds produced by selective laser melting for bone tissue engineering (2009) Tissue Eng Part C Methods, 15 (2), pp. 115-124. , Jul Neovius, E., Engstrand, T., Craniofacial reconstruction with bone and biomaterials: Review over the last 11 years (2010) J Plast Reconstr Aesthet Surg, 63 (10), pp. 1615-1623. , Oct Cabraja, M., Klein, M., Lehmann, T.-N., Long-term results following titanium cranioplasty of large skull defects (2009) Neurosurg Focus, 26 (6), p.
