Fabrication and Bioactivity of Porous Titanium Implant

Abstract:

Article Preview

The aim of this study is to fabricate an implant framework for tissue engineering by sintering titanium beads and coating with hydroxyapatite and test its biocompatibility and bioactivity in vitro. The porous titanium with and without hydroxyapatite coating were involved in study groups. Osteoblastic proliferation, activity of alkaline phosphatase, mRNA of osteocalcin and bone sialoprotein were detected by MTT-assay, ALP test and real-time polymerase chain reaction respectively. The results indicated that the porous titanium material with/without HA coating could promote osteoblastic proliferation significantly contrast to the control group. However, only porous titanium with HA coating increased alkaline phosphatase, osteocalcin and bone sialoprotein gene expression apparently and had statistically differences with the other two groups.
