Microbial adherence to dental implant surfaces is one initiating step in the formation of plaque and is considered to be an important event in the pathogenesis of peri-implant disease [1]. Besides good connective tissue adhesion in the transmucosal part of an implant, titanium implants exposed to the oral cavity require surface modification to inhibit the adherence of oral bacteria. Surface roughness and chemical composition of the implant surface were found to have a significant impact on plaque formation. The aim of the present study was to examine bacterial adherence of differently modified potential implant surfaces. Therefore the surface roughness was decreased and for example a thin ceramic or composite layer of antibacterial material was deposited on abutment surface by sputtering. We analyze the new surface with AFM to control the roughness. For further characterization contact angle measurements were carried out. Biocompatibility and antibacterial effects will be determined in cooperation with the dental clinic at the University Kiel.
