Comparative Evaluation of Residual Contamination on Healing Abutments after Disinfection with Sodium Hypochlorite, 2% Chlorhexidine and Autoclave: An In Vitro Study
Year: 2025
Type: article
Abstract: In order to prevent the transfer of pathogens and biofilm residues, manufacturers recommend new implant HAs for each patient.However, clinicians do reuse HAs to decrease the treatment costs.[4][5][6][7][8] Hence, adequate decontamination is essential for the prevention of infections and attaining good clinical IntroductIonA healing abutment (HA) is a small metal cap placed on the dental implant. 1 They are used to reestablish the anatomic characteristics, thereby restoring the contours of soft tissues.As a part of the healing process, epithelial cells and fibroblasts colonize around the HA, resulting in proliferation and adhesion on the surface. 2 The HAs ensure a complete seal between the internal surface of the implant and the oral cavity, thus preventing the internal implant screw threads from getting contaminated.3 During the osseointegration period, HAs allow for adequate formation of junctional epithelium and connective tissues.4 The HA is designed to serve several purposes.When composed of a biocompatible material such as titanium or titanium alloys, they permit the spread of the nonbony superficial soft tissues during healing and maturation.It also protects the internal surface (usually a screw thread) within the implant body from the impaction of debris during the osseointegration phase.5 Saliva, epithelial cells, food residues, and blood have been found to be the major causative factors for contamination of HAs, and their intensity depends on the patient's habits and maintenance of oral hygiene.Chew et al. in his study has shown that it is quite difficult to effectively remove protein and amino acid contaminants from the surface of HAs. 3
