10 Common Handpiece Maintenance Mistakes

 

  • Poor Autoclave Maintenance - If the autoclave is not properly cleaned and maintained, buildup will occur that will contaminate the entire system, including the handpieces that are sterilized in it.

 

  • Using a Chemical Wipe Down on a Handpiece Before Sterilizing - This is not only redundant, but it may multiply harmful reactions when the handpiece is put through the high temperatures of an autoclave cycle.

 

  • Using an Ultra Sonic Cleaner - Handpiece should never be immersed into any fluids.

 

  • Removing a Handpiece from the Autoclave Too Early - Removing the handpiece before the drying cycle is complete or before the handpiece has cooled down will cause condensation buildup inside the handpiece which will lead to internal rust and the handpiece will be ruined.

 

  • Lubricating the Incorrect Hole - The drive air tube is the only line that leads directly to the turbine or vital moving parts. The rest of the holes acts as exhaust, water, or chip air.

 

  • Failure to Run Handpieces After Lubricating - Not running the handpiece after inserting lubricant can cause the oil to gum up inside the turbine and other moving parts. elaborate

 

  • Not Cleaning the Fiber Optics - Failure to clean the fiber optic surfaces clean will reduce the amount of light that can transmit though the fiber optics thus reducing the brightness of operating field.

 

  • Not Enough Lubricant - Be sure to apply enough lubricant to reach the bearings and moving parts. You cannot over lubricate a high speed handpiece because you can always purge out the excess lubricant. You do not have the same luxury with low speed handpieces.

 

  • Leaving Burs In the Chuck during Autoclaving - When burs are installed in an autochuck,  the springs in the chuck are under tension. Applying extreme heat while under tension will weaken the springs and reduce the lifespan of the chuck. When burs are left in a manual chuck, it can cause a buildup of debris inside the chuck causing problems during operation.

 

  • Dirty Air & Water Lines - Having contaminated air or water lines can also contaminate all handpieces that  run on those lines. You can check if you have dirty lines by purging the lines onto clean white paper towel. If you see any dirt or discoloration, your line may be contaminated.

Step 1: Surface Clean

  • Wipe down the handpiece with a damp disposable cloth. If there is still some bioburden left on the handpiece, clean under running water using a brush. A mild detergent is acceptable. Be sure that all bioburden is removed before proceeding to the next step as it can act as a protective sheild for microorganisms in the sterilizer.

Important:

  • Do not use any chemical solutions for cleaning. Foreign substances may have a negative effect on the sterilizer and/or handpiece through a harmful reaction during the sterilization cycle.
  • Do not submerge the handpiece in water, ultra sonic cleaner, or disinfectant.

Step 2: Choose Adapter for Your Aresol Can of Lubricant

  • Choose the appropriate adapter for the back end of your handpiece and thread the adapter to the lubricant's nozzle. (I Spray recommended) Click here to view the list of our adapters.
  • Insert bur into the handpiece

Note:

  • If you do not have an aresol can of lubricant, you can also use a pen droplet oil (Pen Oil).

Step 3: Spray Lubricant

  • Insert the backend into the adpater and spray lubricant for approximately 2-3 seconds. Count 1...2...3
  • Rotate the bur back and forth between your fingers to further distribute the lubricant in the turbine and help loosen any debris in that area.
  • Connect the handpiece to an air supply. (We strongly recommend use of the DCI HP Flush Station and not the chair-side air line to prevent clogging, cross contamination and discoloration in your air line.)

Step 4: Purge Handpiece

  • Before you apply air pressure; position the head of the handpiece within a paper towel to prevent a mess.
  • Run the handpiece for approximately 10 seconds.
  • If the purged lubricant on the paper towel is not clear, relubricate and purge until the fluid is completely clear.
  • Continue to run the handpiece untill all excess lubricant is expelled.

Step 5: Clean Chuck 

(Recommended once a week)

  • Remove bur and lubricate the chuck using the "Spindle" adapter on your can of lubricant or use a pen droplet oiler (Pen Oil).
  • Using an interproximal brush, clean out the chuck.

Tip:

  • If the handpiece is a push button autochuck, push the headcap to fully open the chuck, witht he chuck held fully open, insert the bur in and out to enact a plunging action. This will loosen any debris in the chuck. Then clean out the debris with the interproximal brush.

Step 6: Dry Handpiece

  • Wipe Down the exterior of the handpiece with a dry towel to remove any expelled fluid or debris. The handpiece should be completely dry at this point.

Step 7: Bag & Sterilize

  • Bag and sterilize according to the manufacturer's  instructions.
  • BE SURE TO ALLOW HANDPIECE TO COMPLETE THE DRYING CYCLE
  • Do not relubricate handpiece after sterilization.

  • Do not submerge the handpiece in water, ultra sonic cleaner, or disinfectant.

Step 2: Lubricate

Note: Lubricate motor every 4-5 autoclaves

  • Using a pen droplet oiler (Pen Oil), insert 2-3 drops of oil into the drive air tube. 

Step 2A: Lubricate (cont)

Note: Only lubricate motor every 4-5 autoclaves

  • Insert a drop of oil into the chuck and speed ring (if available) of the handpiece.

Step 2B: Lubrication Recap

Because there are many different types of motors in the industry,  this image (left) guides you to how much lubrication to apply and to what parts of the motor.

Step 4: Clean Threads

  • Approximately once a month or whenever you see a lot of debris build up; be sure to clean the handpiece threads with a paper towel and isopropyl alcohol.

Step 5: Dry Handpiece

 

  • Wipe down the exterior of the handpiece with a dry towel to remove any expelled fluid or debris. The handpiece should be completely dry at this point.

Step 6: Bag & Sterilize

  • Bag and sterilize according to the manufacturer's  instructions.
  • BE SURE TO ALLOW HANDPIECE TO COMPLETE THE DRYING CYCLE
  • Do not relubricate handpiece after sterilization.

Step 2: Choose Adapter

  • Choose the "E" type I Spray adapter (#ISN-LSE) and thread it to the nozzle of the lubricant. 

Step 3: Spray Lubricant

  • Insert the nozzle into the back end of the attachment and spray for approximately 2-3 seconds or until you see the lubricant exiting the head of the attachment.

Step 4: Disassemble 

  • Unscrew the head of the attachment and remove the oblique shaft. 

Step 4: (Continued)

  • The oblique shaft is the shaft that connects the head and the body of the attachment.  (See image on the left)

Step 5: Lubricate Shaft

  • Insert the oblique shaft into the "E" type nozzle that is already threaded to your can of lubricant, insert the long end first which contains the lubrication hole.
  • Spray lubricant for 2-3 seconds.
  • Assemble the attachment back together.

Step 6: Dry

  • Wipe down the exterior of the attachment with a dry towel to remove and expelled fluid or debris. The handpiece should be completely dry at this point.

Step 7: Bag & Sterilize

  • Bag and sterilize according to the manufacturer's  instructions.
  • BE SURE TO ALLOW HANDPIECE TO COMPLETE THE DRYING CYCLE
  • Do not relubricate handpiece after sterilization.
