Sterilisation occurs in the sterilisator for instruments, drills, planers, matrix, fasteners, clips, endodontic instruments, kits for implantology and surgical linen aprons, compresses, hats, handpieces. Used instruments are submerged into special vessels with desinfecting agents which reduces the bacteri presence for 90%. After office hours are finished, the instruments are transferred into an infrared vessel where the action of desinfecting agent increases by the ultrasound vibration and temperature between 60 and 80 degrees Celsius – thus enabling additional clensing and decontamination.
