dc.description.abstract | [EN] Background: Morphological, physical and chemical properties of both implants and prostheses can determine the
biofilm formation on their surface and increase the risk of biological complications. The aim of this study was to
evaluate the capacity of biofilm formation of Candida albicans on different materials used to manufacture abutments
and prostheses.
Material and Methods: Biofilm formation was analyzed on cp grade II titanium, cobalt-chromium alloy and zirconia,
silicone, acrylic resin (polymethylmethacrylate) and nano-hybrid composite. Some samples were partially
covered with lithium disilicate glass ceramic to study specifically the junction areas. C. albicans was incubated in
a biofilm reactor at 37 °C with agitation. The biofilm formation was evaluated at 24 and 48 hours. In addition, the
morphology of the biofilm was evaluated by scanning electron microscopy.
Results: C. albicans developed biofilms on the surface of all materials tested. Cobalt-chromium alloy showed the
lowest density of adhered biofilm, followed by zirconia and titanium. Silicone and resin showed up to 20 times
higher density of biofilm. A higher biofilm formation was observed when junctions of materials presented micropores
or imperfections.
Conclusions: The biofilm formed in the three materials used in the manufacture of abutments and prostheses
showed no major differences, being far less dense than in the resins. Two clinical recommendations can be made:
to avoid the presence of resins in the subgingival area of implant prostheses and to design prostheses placing
cobalt-chromium alloy/ceramic or titanium/ceramic junctions as far as possible from implants. | es_ES |
