Behavior of pulsed laser deposited hydroxyapatite thin films under simulated biological conditions

摘要

In the present paper, a study concerning the in-vitro behaviour of Hydroxyapatite films obtained by Pulsed Laser Deposition technique on titanium under different conditions was performed. The structures were immersed in Hank's Solution for 21 days in accurately controlled environment conditions. Both film and immersion solution changes were analyzed by means of XRD, SEM, EDX and X-Ray fluorescence respectively. The obtained results point to an excellent behaviour of the obtained films as bioactive structures, recommending this type of covering for further analysis in view of its use in orthopedic and dental implantology.
