DECONTAMINATION
BY COLD ARGON PLASMA
We
use Cold Plasma as advanced technology to clean the titanium
surface of our dental implants. The others use traditional
systems of decontamination which do not guarantee a perfectly
clean surface. Any solvent used to clean, the purest, leaves
inevitably traces on the surface. The impurities and the
solvent molecules combine each other with the chemical constituents
of the surface, especially in the case of reactive materials
as metals. Theoretically, the more functional instrument
of cleaning should be chemically not reagent and, at the
same time, sufficiently strong to remove the contaminations.
We use this principle in the Cold Plasma Cleaning Treatment.
The implant to clean is positioned in Cold Argon Plasma
flux which consists of a non reagent gas atmosphere that
however contains ions, electrons and other chemical
species, which, accelerated by the electric field present
in plasma, crash the surface with the same effects of a
bombing. The physical effect of bombing is to remove and
send away the contaminants from the surface and it allows
to get cleaning levels non obtainable by other techniques.
The possibility to reproduce the treatment and the possibility
to control the process parameters allow to exploit this
treatment to clean the zones difficult to reach offering
an elevated quality constancy.

(LV-SEM observed at 1000X of magnification) after the decontamination
treatment by Cold Argon Plasma: there are not organic contaminations.
