Surface modification of titanium for soft tissue adhesion


An enhanced soft tissue adhesion to titanium can be important in the case of transmucosal dental implants (at collar level) as well as in percutaneous implants. The same devices will benefit from a reduced bacterial contamination do to the high risk of bacterial penetration from the gum/skin passage. Nanogrooves have been obtained by various techniques (mechanical, electron beam) on commercially pure titanium. These grooves exploit the contact guidance principle to for the improvement of soft tissue adhesion and cellular orientation. The proposed grooves do not increase bacterial adhesion. The biological performances of the surface can be improved by the deposition of keratin nanofibers by the electrospinning technique. Nanofibers can be eventually aligned to the grooves. Finally, an effective antibacterial action can be obtained by the addition of inorganic ions within the fibres
