The application of a Mini-TEA-CO2 laser for the modification of titanium surfaces to improve the bonding stability to a PMMA polymer is described. Cast and forged samples of titanium were treated with laser irradiation under different conditions. Depending on the kind of atmosphere employed during the laser treatment a differential change of bonding strength could be estimated. The compound stability was improved by a factor of 40 compared with the reference system. SEM pictures of the surface have shown that no cracks are formed but a modification of the laser-treated Ti surface topography similar to a freeze melting was observed. The results, found for a titanium dental polymer compound, should also be interesting for other medical applications.
