Biofilm formation on restorative materials and resin composite cements

Dental implants made from zirconia can be considered a promising metal free alternative to the well-established titanium implants [1 –4]. Due to the materials' sensitivity to tensile stress, most zirconia implants are offered as one-piece devices. Therefore, a restoration has to be cemented directly on the implant. For cemented restorations on titanium implants, biological complications as a consequence of remaining excess ceme nt were recorded [5–9]. Removing excess cement after fixing a prosthodontic restoration on an implant is challenging for dentists and if not performed adequately, excess cement acts as a co-factor for the development of peri-implantitis due to enhanced biofilm adherence at the rough cement surface .
