Abstract:
Commercially pure titanium (cp Ti) and its alloys are classified as biologically inert biomaterials or bioinert and cannot directly bond with bone in some clinical situations. The aim of this study is investigate the bone bonding ability of a carbon-coated oxide gradient Ti implant, i.e., C-ODTi, by means of transcortical push-out tests in a 3 month experiment using a rabbit model. The pure Ti implant rods were cleaned ultrasonically in ethanol and distilled water and then a poly(vinyl alcohol) (PVA) was coated on its surface. The C-ODTi was obtained by treating PVA-coated Ti rods at 700°C for 1 h in argon. Japanese white rabbits were used and anaesthetized. Each C-ODTi was press-fitted into the prepared holes into the bone marrow. The increase in the interface shear strength reached a maximum after 24 weeks of implantation for all the evaluated materials. These results suggested that there was increased bone formation around the fabricated C-ODTi; that is, the coating of a carbon layer on the implant surface enhanced osseointegration between the bone and the implant. In summary, the fabricated C-ODTi was found to be a promising biomaterial capable of accelerating the bone formation and improving the osseointegration of cortical bone implants.
