Metallic ion release in artificial saliva of titanium oral implants coupled with different metal superstructures

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 degrees 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.
