Achieving Complete Human Gingival Fibroblast Collagen Coverage on Implant Abutments Through Vacuum Ultraviolet (VUV) Photofunctionalization

Treatment of implant abutments with VUV light for 1 minute resulted in a reduction of surface carbon and a transformation of the surface from hydrophobic to hydrophilic. This led to enhanced attachment, proliferation, and retention of human gingival fibroblasts, along with nearly complete collagen coverage on implant abutments. These in vitro results indicate the promising potential of using VUV photofunctionalized implant abutments to enhance soft tissue reaction and sealing mechanisms.
