Mechanical Properties and Corrosion Behavior of Ti6Al4V Particles Obtained by Implantoplasty: An In Vitro Study. Part II

In the field of implant dentistry there are several mechanisms by which metal particles can be released into the peri-implant tissues, such as implant insertion, corrosion, wear, or surface decontamination techniques. The aim of this study was to evaluate the corrosion behavior of Ti6Al4V particles...

The implantoplasty particles showed a higher hardness, strength, elastic modulus, and lower strain to fracture and a compressive residual stress. Resistance to corrosion of the implantoplasty particles decreased, and surface pitting was observed. This fact is due to the increase of the residual stress on the surfaces which favor the electrochemical reactions. The values of corrosion potential can be achieved in normal conditions and produce corroded debris which could be cytotoxic and cause tattooing in the soft tissues.Jorge Toledano-SerrabonaMaria Ángeles Sánchez-GarcésCosme Gay-EscodaEduard Valmaseda-CastellónOctavi Camps-FontPablo VerdeguerMeritxell MolmeneuFrancisco Javier GilMDPI AGarticleimplantoplastycorrosionTi6Al4Vdental implantTechnologyTElectrical engineering.
