Researchers at a Singaporean University have discovered that coating titanium alloy implants with a type of calcium phosphate increases the likelihood of these implants being accepted by the host body.
Specifically, a study by K.A. Khor, H. Li and P. Cheang of Nanyang Technological University investigated and characterized the nanostructures and in vitro osteoblast behaviour of individual hydroxyapatite-coated "splats", which were deposited using both plasma spraying and high-velocity oxy-fuel spraying on polished titanium alloy substrates.
The results showed that the nanostructured hydroxyapatite splats are capable of enhancing the attachment and proliferation of the osteoblast cells.
Hydroxyapatite is the most effective form of calcium...
