Plasma R is an appliance that enables the decontamination and activation of prosthetic structures to be carried out directly in the dentist’s surgery before inserting them in the oral cavity. The technology is the same one used in industry to decontaminate the implants, but the reactor dimensions have been studied especially for chair-side use and for perfect integration with the facilities present in every dentist’s surgery. Plasma treatment, backed up by many scientific studies published in the main reviews in the sector, allows the dentist to carry out surface treatments both on prostheses to be fitted on natural teeth and on implant prostheses, optimising and promoting the bonds of the structures both with the soft tissues and with the adhesive materials. Moreover, in the specific case of implant posts, the total removal of contaminants from the portion that enters the well of the implant allows a better closing of the connection and higher resistance to the unscrewing of the prosthetic screws.
