The aim of the present investigation was to examine the outer‐surface microbiota of the prosthetic connector of Frialit‐2 implants, and to compare the microbial findings with the peri‐implant parameters 2 years after functional loading. In 16 implant‐treated patients (55.8 ± 9.5 years) the outer‐surface micro‐organisms of the prosthetic connectors were determined in 32 Frialit‐2 implants. The functional loading time of the prosthetic suprastructures was 24.1 ± 13.8 months on average. After removal of the implant‐supported restoration, microbial samples were obtained from the outer‐surfaces of the Frialit‐2 prosthetic connector. The microbial plaque samples were specified on CDC‐blood agar as percentages of the total cultivable flora. Actinobacillus actinomycetemcomitans was semiquantitively determined on TSBV‐agar in CFU/ml. The microbial plaque samples were dominated by Actinomyces israelii (68.8%), Eubacterium lentum (56.3%) and Veillonella parvula (43.8%) with proportions ranking between 3.9% ( V. parvula ) and 11.1% ( A. israelii ). The most frequently detected gram‐negative microorganisms were Fusobacterium nucleatum (87.5%), Porphyromonas gingivalis (81.3%), and Peptostreptococcus micros (68.8%) with enhanced proportions for P. gingivalis (11.4%) and P. micros (11.4%). No statistical significant correlation could be established between the microbiota present on the outer‐surfaces of the F2‐connector and the peri‐implant parameters examined. The outer‐surface microflora recovered from the implanto‐prosthetic‐connector of Frialit‐2 implants reveals a colonization with gram‐positive bacteria and potentially harmful gram‐negative micro‐organisms that were frequently detected, but present at low levels. After 2 years of restorative loading, the outer‐surface microbial colonization is compatible with peri‐implant soft tissue health.
