Bioactive Porous Titanium: An Alternative to Surgical Implants

: Porous titanium implants have been used to improve implant–bone attachment by the ingrowth of bone tissue within the porous structure. Despite the efficient bone adhesion of porous titanium implants, chemical bonds are required at bone–implant interface. These implants can become bioactive by a biomimetic precipitation process. The aim of this work was to enhance the bioactivity of pure porous titanium implants by biomimetic process. The samples immersed in a simulated body fluid promoted the nucleation and growth of calcium phosphate (Ca‐P) crystals, such as hydroxyapatite (Hap), on the material surface. Scanning electron microscopy, energy dispersive spectroscopy, and Fourier transform infrared spectroscopy analyses revealed that a Ca‐P deposition occurred without the need of pretreatments to improve the surface bioactivity. This present study indicates the potential for growing a bone‐like Hap layer on porous titanium implants by biomimetic processes.
