SOME BIOLOGICAL AND PHYSICAL-PROPERTIES OF LASER-DEPOSITED HYDROXYAPATITE BASED FILMS

The preliminary results of biological and physical tests of hydroxyapa tite thin films deposited on dental implants by a new technology with the KrF excimer laser ablation method were evaluated. Biological and p hysical properties were studied and analyzed by the lymphocyte prolife ration test and scanning electron microscopy (SEM), X-ray analysis, Ru therford backscattering analysis (RES) and particle induced X-ray emis sion (PIXE) methods. Ten bioceramic films from 45 samples had very goo d physical-and biological properties. Creation of hydroxyapatite thin films with laser ablation can have a positive effect on adhesion of th e film and protection for corrosion.
