Abstract
In the present study, the formation of calcium phosphate crystals was investigated in order to apply the thin film produced by the molecular precursor method as dental implant material. After the application of the precursor solution firing at 600℃ formed a crystalline carbonate-containing hydroxyapatite film on the titanium substrate. The greater amount of formation of calcium phosphate crystals was observed on the titanium coated with carbonate-containing hydroxyapatite thin film compared with non-coated titanium after 1 day immersion in Hanks' balanced salt solution. After 7 days and 14 days immersion, the phosphate was carbonate-containing hydroxyapatite, which was aligned in C axis in thin film X-ray diffraction and Fourier transform infrared spectrum. In conclusion, it is expected that the carbonate-containing hydroxyapatite thin film, produced by molecular precursor methods, will have excellent bone compatibility.
