Dental Handpieces: Maintenance, Use, and Repair Guide
Dental handpieces are one of the most essential tools in any dental practice. Whether used for drilling, polishing, or cutting, these high-speed and low-speed instruments enable dentists to provide precise and effective treatment. However, to ensure optimal performance and longevity, dental handpieces require regular care, including proper cleaning, lubrication, sterilisation, and occasional repairs.
In this comprehensive guide, we’ll cover everything you need to know about how to oil dental handpieces, clean them, disinfect, sterilise, hold them correctly, and even repair them. We’ll also discuss which type of dental handpiece is the most versatile and how much you can expect to invest in these vital instruments.
What Is a Dental Handpiece?
A dental handpiece is a handheld device used primarily to cut hard and soft tissues in the oral cavity. They come in two main types:
-
High-speed handpieces, which rotate at speeds up to 400,000 RPM and are used for cutting enamel and dentin.
-
Low-speed handpieces, which operate at slower speeds (up to 40,000 RPM) and are used for polishing, finishing, and caries removal.
Dental handpieces are typically air-driven or electric, and they use various burs or attachments depending on the procedure.
How to Hold a Dental Handpiece
Holding the handpiece correctly is crucial for precision and patient comfort. The most common grip is the pen grip, where you hold the handpiece like a pen, using your thumb, index, and middle fingers to stabilise and guide it. This grip offers better control and reduces hand fatigue.
For some procedures, a palm grip may be used for more force, especially when polishing. Proper handpiece ergonomics also help prevent repetitive strain injuries.
How to Clean Dental Handpieces
Proper cleaning is the first step in handpiece maintenance and infection control:
-
External Cleaning: Wipe the handpiece thoroughly with a soft cloth or brush soaked in mild detergent or enzymatic cleaner. Avoid soaking the entire device.
-
Flushing: Use water or cleaning solution to flush out internal canals to remove debris and lubricants.
-
Drying: Allow the handpiece to dry completely before lubrication.
Always follow manufacturer-specific cleaning guidelines to avoid damage.
How to Oil Dental Handpieces
Lubrication is vital to prevent wear and overheating. Here's how to oil your dental handpiece:
-
Use handpiece-specific oil, usually supplied by the manufacturer.
-
Attach the oil applicator to the handpiece’s drive air tube or oil port.
-
Apply a few drops of oil (usually 2-3) into the drive air inlet.
-
Run the handpiece for 20-30 seconds to distribute oil evenly.
-
Wipe off any excess oil.
How Often Should You Oil Dental Handpieces?
Dental handpieces should be oiled after every use or at least once daily, depending on your practice volume. High-speed handpieces often require more frequent lubrication due to higher operating speeds.
Consistent lubrication prevents bearing failure and prolongs handpiece life.
How Long Should a Dental Handpiece Be Lubricated For?
After applying oil, run the handpiece for approximately 20-30 seconds to ensure thorough internal distribution. Over-oiling can cause excess residue, so follow manufacturer instructions carefully.
How to Disinfect Dental Handpieces
Disinfection involves killing or inactivating microorganisms on the handpiece surface:
-
Use EPA-registered disinfectant wipes or sprays suitable for medical devices.
-
Apply disinfectant to external surfaces after cleaning.
- Avoid harsh chemicals that can damage seals and bearings.
Note: Disinfection is different from sterilisation and should not replace it.
How to Sterilise Dental Handpieces
Sterilisation is critical for infection control and must be done after every patient:
-
Ensure the handpiece is cleaned and lubricated before sterilisation.
-
Use an autoclave (steam steriliser) following the manufacturer’s cycle recommendations (usually 134°C for 3-4 minutes).
-
Allow the handpiece to dry completely before storage or use.
Never use chemical sterilants unless specified, as they may damage the device.
How to Repair Dental Handpieces
Minor repairs like replacing O-rings, bearings, or turbines can often be done in-house by trained technicians. However, for major repairs or overhauls, it’s best to send the handpiece to an authorised repair centre or manufacturer.
Common signs a handpiece needs repair include:
-
Excessive noise or vibration
-
Reduced speed or power
-
Overheating
-
Visible damage
Regular maintenance can help prevent costly repairs.
When Cleaning a Dental Handpiece, It Is Important To…
-
Follow manufacturer guidelines strictly
-
Use compatible cleaning agents and lubricants
-
Avoid submerging the handpiece in liquids unless specified
-
Flush internal channels to remove debris
-
Ensure complete drying before sterilisation
Proper cleaning reduces infection risks and extends equipment life.
Which Dental Handpiece Is the Most Versatile?
The contra-angle low-speed handpiece is often considered the most versatile. It can be used for polishing, caries removal, and adjusting prosthetics. Additionally, high-speed air-turbine handpieces are indispensable for cutting hard tissues quickly.
Many dentists keep both types on hand to cover all clinical needs.
