Handpiece maintaince

There are two methods of cleaning dental handpieces. One is to use an automatic handpiece system, such as the QUATTRO care Plus, prior to sterilization. The other option is to manually maintain your handpieces. If you elect to manually maintain your handpieces, here are the steps to do so. 
 
 
Step 1: Clean Handpiece
The first step in cleaning a dental handpiece is to lightly wash the handpiece under cool running water to remove excess debris.

Step 2: Handpiece Lubrication
Following external cleaning, connect the handpiece to the handpiece lubricant spray using the appropriate nozzle for the handpiece you are cleaning. For this air handpiece, we are using a multiflex nozzle.  Spray for approximately 2 seconds. We recommend using a cloth or paper towel wrapped around the handpiece to contain the spray. It is ok if some excess lubrication remains in the handpiece.

Step 3: Purge Handpiece
After lubrication, you'll want to purge your handpiece. Simply connect the handpiece to your multiflex connection, step on the foot petal and purge for 30-40 seconds. The handpiece is now ready for sterilization.
