Implantation Of Periosteum On Titanium Grafts

Scholars from the Faculty of Nuclear Technology Engineering and the Faculty of Engineering of New Production Technologies of the Tomsk Polytechnic University in Russia, as well as foreign specialists in the field of medical materials, have developed a method of using titanium dioxide nanotubes. The catheter is coated with a calcium phosphate coating. The composition of the coating is the same as that of human bone. It is equivalent to covering titanium grafts with periosteum, which can improve the survival rate of titanium grafts.

The researchers noted that titanium is widely used for grafts, but the two have different elasticities. Titanium is much harder than bone tissue. As a result, titanium is subjected to more mechanical loads than bone when the patient is active, which can lead to bone tissue damage. "The nanoscale catheter helps solve this problem and avoids subjecting titanium to more mechanical loads than bone tissue," said graduate student Roman Chernozem.

In addition, the hollow nanoscale catheters are ideal for filling with drugs, delivering them to the body where it needs them, and controlling the rate at which the drugs are delivered.
