Maintenance of Dental Micromotor Handpiece

In the daily use of a dental clinic, dental micromotor handpiece is one of the most commonly used equipment. However, frequent use inevitably leads to wear and tear, affecting its lifespan. So, how can we extend the lifespan of dental micromotor handpiece while ensuring safety and compliance? The detailed maintenance methods are introduced below.

Lubrication Maintenance of Dental Micromotor Handpiece

Lubrication is the key step in the maintenance of dental micromotor handpiece. Proper lubrication can effectively reduce the wear and tear of the bearings and mechanisms, while also preventing parts from rusting. If the handpiece is not used for a long time, special dental handpiece lubricant must be injected and stored in a sealed bag.

Daily Post-Use Maintenance of Dental Micromotor Handpiece

After using the dental micromotor handpiece, the following maintenance steps should be followed: cleaning—lubrication—packaging—sterilization—dry storage. Follow this sequence: clean first, then sterilize. If not cleaned properly, residues inside the handpiece can lead to biofilm formation, inhibiting effective sterilization.

Cleaning Steps

The first step is cleaning. After use, blow debris by continuously pressing the foot pedal for 30 seconds, then remove the handpiece for cleaning. Wash the exterior under running water for at least 30 seconds, and use a special cleaning agent for the interior. Check the cleanliness by spraying cleaning agent until the expelled agent is clear.

Lubrication Maintenance

The second step is lubrication, a crucial preparation before sterilization. Use an oiling machine for high-pressure lubrication, then blow out excess oil from the interior to ensure water vapor can penetrate during sterilization. Proper lubrication reduces wear and keeps the handpiece running smoothly.


The third step is packaging. Place the lubricated handpiece into suitable packaging bags, seal them, and prepare for sterilization. The purpose of sealing is to avoid contamination during the sterilization process.


The fourth step is sterilization. After cleaning, sterilize using high temperature and pressure to ensure complete microbe elimination. Place the sealed handpieces in an autoclave, select an appropriate mode for instrument sterilization. Do not overfill or place handpieces near heat sources to avoid structural damage.

Dry Storage

The fifth step is dry storage. Do not open the packaging before use; store in a clean, dry place. Dry storage prevents internal rusting, extending the handpiece's lifespan.

Strictly following the above steps for maintenance of dental micromotor handpiece can extend its lifespan by 5 to 10 times compared to normal handling. Thus, maintaining each step's sequence is crucial for prolonging the handpiece's life.

Furthermore, dental micromotor handpiece is mainly made of steel with intricate internal structures that constantly need lubrication. However, excessive lubricant can impede the bearings' normal function, reducing the handpiece's efficiency and affecting sterilization. Therefore, it is recommended to use a special oiling machine for controlled, even distribution of lubricant inside the chamber.

In conclusion, proper maintenance methods not only extend the lifespan of dental micromotor handpiece but also ensure stability and safety during treatment. I hope the above maintenance tips will aid your daily work.
