Abstract

The possibility of pulsed laser deposition of thin films from human tooth targets was studied, since bioceramic thin film coatings on dental and orthopaedic implants may have their surface characteristics for biointegration improved. Pellets were pressed from tooth powder at different pressures and ablated with pulses of ArF (λ = 193 nm) and KrF (λ, = 248 nm) excimer lasers with fluences up to 4.5 and 12J/cm2, respectively. Layers were deposited onto heated (250°C) titanium, glass, and KBr substrates. The increase of the pellet pressing pressure from 150 to 450 MPa enhanced the roughness of the deposited films. IR spectroscopic measurements showed that the chemical composition of the films were close to that of original tooth material under appropriate fluence. The adherence of the layers to the substrates could be significantly improved by post annealing at 550°C.
