Paper Abstract

A new method for surface processing of bioceramic materials like hydroxyapatite (OSPROVIT) has been investigated in this study. A proper surface preparation including retentive areas should lead to highly activated surfaces to adsorb biological active molecules for a good tissue/implant bonding. With the ArF-excimer laser ((lambda) equals 193 nm) it seems to be possible to get such surfaces by a process called photoablation. Mass spectroscopy and electron beam induced microanalysis of elements show that photoablation takes place without changes in the chemical structure. SEM pictures will point out the advantage of this laser type in the preparation for these biomaterials. Temperature measurements show that the thermal stress is acceptable and in a defined forming process the good workability is demonstrated.
