Objective: The main aim of this work was to evaluate the multi-species biofilm formation in vitro on surfaces of dental abutment and implants.
Methods: Five commercial implant-abutment assemblies (Titamax CM; Neodent?, Curitiba; Brazil) were assessed in this study. Also, commercially pure (cp) titanium grade IV square samples (10?10?1 mm) were used to prepare surfaces similar to those of titanium implant and abutments (n=10). Titanium square samples and implant-abutment assemblies were placed into 24 well-plates containing diluted human saliva at 37?C under microaerophilic conditions (5% CO2). After 24, 48, 72 and 96 hours of incubation, biofilms were analyzed by scanning electron microscopy (SEM) and microbiological analyses.
Results: The multi-species biofilm for.. View More»
