Abstract: In this work the metallic ion release in oral implants with superstructures of different metals and alloys used in clinical dentistry has been determined. This study has been realized in a saliva environment at 37°C. The measurements of the ion release were carried out by means of the Inductively Coupled Plasma Mass Spectrometry technique. The titanium oral implant coupled with a chromium-nickel alloy releases a high quantity of ions and the implant coupled with the titanium superstructure presents a low value of ion release.
