Paper Title:
Evaluation of Biomimetic Solution for Coating Powder Metallurgy Porous Titanium Samples
  Abstract

In order to improve implant-bone attachment, porous titanium has been used to achieve the ingrowth of bone tissue within the porous structure. Although this biomaterial has shown efficient bone adhesion for orthopedic and dental implants, the ideal surface must have chemical bonds at the implant-bone interface. In this work, samples of pure porous titanium were produced by powder metallurgy technique and submitted to biomimetic process in order to evaluate the material’s bioactivity and to enhance its osteoconductivity. The samples were immersed in modified simulated body fluid (mSBF) which induces the nucleation and growth of a calcium phosphate bioactive film and a chemical bond with titanium. SEM, EDX and FTIR analyses showed that a calcium phosphate deposition occurred without the need of pre-treatments to increase the surface bioactivity. As a result, this research revealed the potential for obtaining a bonelike apatite film on this porous titanium by biomimetic method.
