Patients that need implant supported restoration were recruited for this study. At baseline a specific abutment was screwed at 20 N.Two months following healing abutment placement clinical measurements were evaluated.~Endopoints of the study:~Histological outcomes at 2 using traditional histological staining (ematossilin/eosin) Immunohistological outcomes at 2 using different stainings. Postoperative complications. Comparison between the histological outcomes and the preoperative clinical evaluation of the sites
Objective of the present study was to assess the peri-implant soft tissue profiles between argon plasma pre-treated (PT) and non-treated (NPT) abutments by comparing clinical and histological parameters 2 months after abutment placement.
