Resumo
Porous titanium allows bone formation and bone ingrowth in vivo providing a better implant fixation of surgical implants. Some important parameters of porous biomaterials are porosity, pore size, pore shape and pore homogeneity as they influence mechanical properties and biocompatibility. Many techniques have been used to characterize these parameters and different kinds of information can be achieved depending on the method used. Porous titanium samples were manufactured in this work by powder metallurgy, using pure titanium powders mixed with a pore former additive. The porosity quantification was assessed by geometric method, gamma-ray transmission technique, quantitative metallographic analysis and computed x-ray microtomography. Qualitative evaluation of pore morphology and surface topography were performed by optical microscopy, scanning electron microscopy and confocal scanning optical microscopy. The results allowed the comparison of the different techniques and the determination of the advantages and difficulties of each one, according to the samples studied.
