New technology for the removal of corundum residues on dental implants

Surface modification is an important measure to improve dental implants. Corundum residues, which are part of current dental implant blasting, on Straumann dental implants, were found to have disappeared in recent publications. We further evaluated this new cleaning technology by evaluating the surface of four different Straumann implants using scanning electron microscopy (SEM) and energy-dispersive radiographic spectroscopy (EDX). The involved technology fits to a Straumann patent involving a dextran coating allowing easy corundum particle removal by aqueous solution.
