Figure 2: (A) SEM micrograph of commercial abutment-implant assembly. (B) Upper view of the platform revealing rough (SLA) and polished surfaces. (C) Topography of the commercial SLA surface covered with a multi-specie biofilm grown for 72 h in BHI medium with 5% sucrose. (D) Microgap size at the implant-abutment connection. SEM micrographs obtained by secondary electron (SE) mode at 15-20 kV.
