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.

OPERATION

 

In the various phases of laboratory processing a series of residues of various origin builds up on the surface of the prosthetic components; if not correctly removed, these residues are transferred into the implant connection, preventing a perfect seal and creating a possible point of access for the infiltration of bacteria. In addition, the contaminants that remain on the crown surface have a negative influence on the adhesion of the soft tissues and often prevent optimum adhesion with the finishing materials. Plasma treatment, which is triggered in the special vacuum chamber of the Plasma R reactor, generates an ionic bombardment with Argon gas, which detaches the contaminants from the surface of the prosthetic product and converts them into their gaseous phase, which is ejected at the same time, removing any residue. This process also generates a reduction of the surface tension which increases wettability and prepares the surface of the prosthesis for chemical and physical interaction with the adhesives, also promoting the bond with the soft tissues.

FIELDS OF APPLICATION

 

– Cleaning and activating implant abutments;

– Cleaning prosthetic rehabilitations (crowns and bridges in alloy, metal-free porcelain) to increase their adhesive cementing processes;

– Cleaning and activating prosthetic structures to increase their adhesion to the porcelain;

– Cleaning porcelain veneers (disilicate and zirconia) to optimise the adhesive cementing processes.

 

To operate the appliance you must purchase a cylinder of Argon gas, not supplied by Sweden&Martina; apply to your local specialised dealers.
