This process partially dissolves the SiO<sub>x<\/sub> nanoparticles, allowing the emerging TiO<sub>x<\/sub> nanoparticles to agglomerate into larger porous structures. This also allows for the introduction of SiO<sub>x<\/sub> nanoparticles into the structure of the agglomerates, resulting in formation of porous titanium surfaces containing TiO<sub>x<\/sub>\/SiO<sub>x<\/sub> nanoparticles, which leads to significant improvement of osseointegration and adhesion of bone tissue to the titanium implants.
