Dental handpieces have evolved significantly over the years and they remain a vital part of dentistry today. The care and maintenance of these instruments is essential to preserving not only the life of the instrument but its proper function as well. While traditional air driven handpieces are still a mainstay in dentistry, electric handpieces are now being more widely used. The newest technology takes components from both electric and air driven handpieces. Understanding how to clean and maintain these handpieces and their components properly will help the clinician achieve optimal results. Knowing when to replace or rebuild handpiece turbines and its pros and cons, and knowing who to send the handpiece to for repairs is essential for quality and turnaround times.
And today we’ll introduce you 12 tips to extend the life of your handpiece and
the most common mistakes when using it:
1. A handpiece should never be wiped down with a chemical disinfectant. When heated, the chemicals may react with the metal shell causing a buildup and corrosion. If left unattended, they will shorten the lifespan of the instrument.
2. Apply a sufficient amount of cleaner/lubricant. The cleaner/lubricant should come out of the head of the handpiece to ensure all bearings and have been thoroughly covered with the lubricant.
3. Make sure you are lubricating the drive air line. Only the drive air hole goes to the turbine. Lubricating the wrong hole will result in improper turbine lubrication.
4. Use the correct cleaner/lubricant. Always use the manufacturer’s recommended lubricant with their respective nozzles and expelling maintenance couplers/ adapters.
5. Properly clean the chuck to remove any excess debris at least once a week to maintain the mechanism that holds the bur. This helps ensure the bur does not come out during a procedure.
6. Never place the handpiece in the ultrasonic cleaner, unless the manufacturer has a recommended product. The handpiece should never be immersed in any liquid as damage may occur.
7. Properly clean the fiber optic/LED lens. After use it’s important to run under water and gently wipe with a sponge to remove all outer debris. Failure to do this will result in a buildup on the lens and poor light quality. You may also use a cotton swab dampened with isopropyl alcohol to remove embedded debris.
8. Unless the handpiece utilizes a wrench-activated chuck, remove the bur when cleaning and lubricating and expelling. Leaving the bur in the chuck while lubricating prevents the lubricant from flowing where it needs to go to ensure proper coverage of the bearings. Always remove all burs prior to sterilization. In the autoclave, the springs in the chuck are compressed. The heat will cause these compressed springs to weaken under tension. Debris can also accumulate around the chuck, causing it to corrode and shorten the life of the instrument.
9. Expel excess lubricant by running the handpiece after lubricating and before autoclaving. This is important. If the handpiece isn’t run to expel the lubricant, it can cause a gumming effect around the turbine where it will be essentially baked in. Many times this will cause the expulsion of excess lubricant when used for the first time after autoclaving.
10. Let the handpiece cool down. Never run the handpiece under cold water to quickly cool it off. This damages the turbine.
11. It is important to follow the manufacturer’s guidelines on air pressure. Excessive air pressure could cause damage to the turbine bearings.
12. Always maintain a properly working autoclave.
It’s important to check the handpiece coupler on the dental hose as well, at least once a week. O-rings should all be present and in good condition. O-rings can be obtained from the manufacturer and replaced as needed. Couplers need to be lubricated and cleaned using the lubricant and a towel or gauze pad. The towel or gauze is moistened with the lubricant/cleaner then wiped in a circular motion to clean debris and rehydrate the O-rings making sure the bulb cap stays snug.
