How Not To Clean Your Highspeed Handpiece

It is important that you neverever submerse your highspeed handpiece in any liquid solution, or place it in the ultrasonic cleaner without first removing the turbine, o-rings, springs & clips.

I have had a couple of calls recently from clients experiencing bearing failure who wanted me to see if I could pin-point the reason.

It was easy to determine the Dental Handpiece suppliers had been submersed in liquid and placed in the ultrasonic, without first removing the turbine. Upon questioning my clients, it was revealed someone had told them if the highspeeds seem a little sluggish, to place them in a zip lock bag, fill it with vinegar and place in the ultrasonic.

Anyone who gives you this kind of advice is either incompetent or malicious. I would be suspicious of anything else they might tell you.

No matter what brand you have, this process is devastating to the turbine! Every manufacturer of highspeed handpieces tells you specifically not to submerse the highspeed in any liquid.

The ultrasonic cleaner will remove the grease from the bearings, ruining them, even without using any cleaning agents; and the grease, when dislodged will find another place to go (not a good thing). It also distorts the o-rings and removes lubrication from the chuck assembly, which will cause it to fail as well.

The bottom line is, a rebuild will not be practical, and the entire turbine will have to be replaced. It should go without saying, it will also void any warranties you may have.

As in dentistry, symptoms are indicative of a greater problem that must be addressed. If your highspeed handpiece is running sluggish, there is an underlying cause and treating the symptoms will not cure the problem.

When you notice sluggishness or any other problem, it’s best to set it aside and use another one. But, if you must use it to get through a procedure, you can try placing a couple of drops of oil into the intake tube.

Once the procedure is completed, send it out to a professional for diagnostics (you should not be charged for this process).

While vinegar is a good cleaner, it does leave a residue that will eventually end up in the bearings, air lines & water lines and possibly even in the patients mouth.
