Blood Coagulation on Titanium Dioxide Films with Various Crystal Structures on Titanium Implant Surfaces.

Titanium (Ti) is one of the most popular implant materials, and its surface titanium dioxide (TiO) provides good biocompatibility. The coagulation of blood on Ti implants plays a key role in wound healing and cell growth at the implant site; however, researchers have yet to fully elucidate the mechanism underlying this process on TiO. This study examined the means by which blood coagulation was affected by the crystal structure of TiO thin films (thickness < 50 nm), including anatase, rutile, and mixed anatase/rutile.

Improving the initial biocompatibility of a titanium surface using an Er,Cr:YSGG laser-powered hydrokinetic system.

Objectives: This study was designed to improve the initial biocompatibility of titanium (Ti) using an Er,Cr:YSGG-powered hydrokinetic system.

Methods: The Er,Cr:YSGG-powered hydrokinetic system with different laser energy densities, 125 and 190 J/cm(2), were applied to the Ti substrate. Human osteosarcoma U2-OS cells were used.
