Plasma Treatment Maintains Surface Energy of the Implant Surface and Enhances Osseointegration

Figure 3

Representative overview of the histological micrographs of the plateaus at 2-week experimental period. (a) The histologic sections of the NWRBM group although presented layers of early connective tissue (stroma) filling the region between plateaus (arrows), there are some areas that the stroma collapsed (arrows). (b) The histologic sections of the Plasma 30 days group showed initial signs of bone formation adjacent to the implant surface (arrows) and the presence of layers of early connective tissue (stroma) filling the region between plateaus without detachment of the surface (arrows).
