Maintenance for High speed handpiece

High speed handpieces are a vital part of any dental practice. The use, care and proper maintenance is essential to preserving their lifespan. Proper cleaning and sterilization will keep your handpiece running longer and prevent the spread of infectious diseases. It is important to use the manufacturers recommended cleaning instructions and products so the warranty is not voided. The purpose of internal handpiece maintenance is to dissolve and remove dirt, debris and contaminated oils, leaving clean oil behind for lubrication. The lubrication of any handpiece is essential to its function. When these things are done correctly and consistently, you will preserve the lifespan of your instrument.

Electric Handpieces

Electric handpieces have gained popularity for their quiet presence and can be used at the chair or in the lab. Maintenance of electric motors is limited and brushed motors are not autoclavable. There are two types of electric motors; those with carbon brushes and brushless. In a brushed motor, there are carbon brushes which can wear down and need to be replaced over time. The brushes produce a carbon dust that can build up in the motor and shorten its life. The oil from the attachment can mix with the carbon dust producing black grease that is hard to remove. It’s recommended to clean the motor weekly and replace the brushes twice a year. This usually requires a special instrument to unscrew the brushes if you choose to do it yourself. The manufacturer has recommendations for use and care. The newest electric motors on the market are brushless. Its design is a contactless magnet system which keeps the motor quiet and smooth. It has very low vibration and in most cases, there is no maintenance.

In many models, lubricating the electric handpiece attachments is done the same as the traditional air driven style. Sterilization for each handpiece varies. It is important to research the different handpieces before purchase to make sure you are acquiring the handpiece that best fits your needs. Make sure to follow proper manufacturers’ maintenance procedures to the letter as not to void the warranty. When an electric handpiece begins to show signs that the mechanics are slowing down, stop using it immediately. Continued use of the handpiece can result in more costly repairs.

The FDA has received reports of severe burns caused by pneumatic and electric handpieces. In most of these cases, burns were caused by overheating of various handpiece components. After research, it was found that overheating was due to failure to service and maintain the handpieces in accordance with the manufacturer’s recommendations. When electric handpiece systems aren’t well-maintained, the handpiece head can overheat very rapidly. As a safety precaution, it is necessary to maintain the handpiece properly. Failure to properly clean and maintain the electric handpiece will also void its warranty.

Slow or Low speed motor maintenance

Slow speed motors require less maintenance and do not require as much lubrication as high speed motors. The viscosity of the oil is different as well. Some models of slow speed motors require higher viscosity oil. A couple of drops in the drive air line is all that’s needed. Also apply some oil as a preventative measure to forward/reverse valves, shift rings, and sheath attachment points.

Run the motor to distribute the oil. Wipe away the excess oil with a paper towel. Periodically disassembling the motor and cleaning it of buildup and debris will ensure longer life. Straight attachments require lubrication. Running it under water and cleaning with a sponge to remove debris is all that is needed before placing it in a bag for sterilization. Latch type or right angle attachments can be done the same way, by placing a few drops of lubricant and run for at least 20 seconds to distribute the oils before autoclaving.
