The Major Causes Of Handpiece Failure

  • Sterilization
  • Lack of lubrication or proper lubrication
  • Being dropped
  • Ran with a bent bur or no bur at all
  • Excessive air pressure lack of proper lubrication

Handpiece maintenance is the key to survivability. By properly cleaning and lubricating your handpiece before sterilization you insure that it will have a long life and run at its best Running your handpiece at the Manufacturer’s suggested air pressure is very important. Higher air pressures will make your handpiece run faster but will cause premature bearing retainer wear.
Sterilization cannot be avoided and must be done in accordance with ADA/FDA regulations. Most Manufacturers recommend using an Autoclave or Chemiclave. Dry heat and cold sterilizing is generally not recommended.
By using a quality lubricant/cleaner and following the procedures below you should see longer handpiece life.

Handpiece Cleaning & Lubrication Procedures

1. Clean exterior of handpiece using isopropyl alcohol and a towel
