Adhesion of Porphyromonas gingivalis and growth of human gingival fibroblasts on modified titanium dental implant surfaces exhibiting 1000-nm spikes.

Objectives: The aim of this study was to assess the antibacterial efficacy of nanostructured dental implant surfaces against Porphyromonas gingivalis, a crucial bacterium in the progression of peri-implantitis. Additionally, to evaluate the possible effect of the modified implant surface on the viability of human gingival fibroblasts (HGnFs).

Method And Materials: As detailed in prior research, helium ions sputtering was used to produce nanospiked titanium surfaces with a height of 1000 nm (Ti1000).
