      2. Automated Cleaning & Disinfection

      Cleaning your equipment is an essential but often overlooked process causing early fatigue in different components. Why is cleaning so important and isn't it enough to simply oil and sterilize it? 

      Either cleaning your instruments through a thermal disinfector or through the manual process ensures that (visible) debris is removed which is relevant medically and mechanically. Through the cleaning process, the bacterial count can be reduced up to 1/1000 in comparison to the initial count according to recent studies. So to prevent cross-contamination among patients and health staff. Kindly note that though it might not be required by law in your country (German laws require it according to the standards of the RKI) it is required according to our instructions for use.

      Secondly cleaning your instruments will drastically reduce the repairs as debris within the handpieces is broadly removed from bearings, gear sets, and all other relevant components. This debris is a mixture of internal and external matter such as old lubrication and grease, small metal parts resulting from friction in the bearings and gears, as well as saliva and blood forming a polishing paste over time that harms bearings, gears, o-rings and technically everything that come in contact with it.

      IMPORTANT NOTICE

      Do not clean your instruments in an ultrasonic cleaner (even equipment "specifically designed" for handpieces such as Gamasonic, etc.) as it will lead to fast and permanent damage of the bearings. This is standardized among all handpiece manufacturers - kindly check the instructions for use for confirmation.
       
      Automated Cleaning & Disinfection Process:

      a) Required equipment:

      • Thermal disinfection device (MK-dent used WD BHT INNOVA M3 for validation)
      • Ensure the thermal disinfector is properly maintained by an authorized service technican
      • Cleaning solution (MK-dent used Dr. Weigert Neodisher MediClean forte 0,5% for validation)
      • Suitable adapter for handpiece connection (Available from thermal disinfector manufacturer)
      • Ensure the water quality is equivalent to the EU-drinking water directive

      b) Ensure the following steps are executed properly:

       

      Cleaning & thermal disinfection

      - 1 minute of cleaning with 0,5% Neodisher MediClean forte at 30°C or 86°F

      - 6 minutes of cleaning with 0,5% Neodisher  MediClean forte at 55°C or 131°F

      - 1 minute of flushing with demineralized water

      - 5 minutes of thermal disinfection with  demineralized water at 90°C

       

      In case you are using a cleaning & disinfection machine that is based on a chemical instead of thermal process (NSK iCare, etc.) please ensure that all chemicals are flushed out correctly. Are you curious what will happen if the solutions are not properly removed? Click here to see the results.

       

      Drying

      Usually, the drying cycle is part of the drying cycle, but please ensure to verify if this is the case. If you detect moisture after the entire process is finalized, it is necessary to dry the handpieces with compressed air.

      High quality handpieces are made and coated from corrosion-resistant materials so they will not corrode under normal circumstance. If the drying is not properly executed, the moisture left on the handpiece will attract several aggressive substances, that will settle on the material, which may cause a corrosive effect.
