Presentation of a study on the risks associated with the reuse of healing abutments from one patient to another. Thesis by Edouard Boubée, year 2019, Université Clermont Auvergne - Unité de formation et recherche d'odontologie.
Objective : The aim of this study was to determine whether the zirconia coating on Profile Designers iphysio® allows them to be sterilized and decontaminated for reuse.
Methods : Scanning microscope observation of previously used and decontaminated Profile Designers iphysio® and healing abutments. These used healing abutments were compared with new healing abutments. The residues present on the healing abutments and Profile Designers iphysio® were analyzed using a spectrometer to determine the composition of these residues.
Results : Sterilization and decontamination of Profile Designers iphysio® did not completely remove any contaminants, despite the zirconia coating, which is less adherent than titanium.
Conclusion : The reuse of healing abutments of any kind, due to the impossibility of completely eliminating all traces of contaminants, systematically entails a risk for the patient receiving the previously used abutment.
