The Best Way to Maintain A Dental Electric Motor:Dealers and Dentists Can Easily Master It!

Dental handpiece is an indispensable tool for high-frequency use in dental clinical work, which can hold the bur to complete the preparation of the tooth, trimming, caries removal, etc. They are categorized according to the source of power provided and can be divided into dental electric handpiece and dental turbine handpiece; the former uses an electric motor to provide power to run, and the latter relies on the air pressure to push the turbine to run.

In recent years, the use of dental electric motor has become more and more popular among dentists, and even dentists in some areas have been using only electric handpieces. So, how should we take good care of dental electric micromotors in daily operation?

Cleaning method

1. Using a rag soaked in alcohol or a soft disposable towel；
2. Wipe the main unit, motor hose, motor connector, and contra-angles.
3. Remove residue of cleaning solution with a damp cloth until there is no visible residue.

Attention：

Be careful when cleaning the main unit and electric motor connectors. Avoid getting liquid into the electric motor main unit to avoid short-circuiting or malfunctioning.

Sterilization method

1. Wipe all surfaces of the device with a clean disposable cloth soaked in disinfectant for a minimum contact time of 3 minutes.
2. Wipe the dental electric motor all parts with a cloth soaked in ionized water to remove all disinfectant. The contact time is at least 30 seconds.
3. Repeat with a damp cloth for 30 seconds, discarding the cloth as soon as it is used.
4. Repeat with a damp cloth for 30 seconds and discard when finished.

Only electric motors and electric contra angles are suitable for drying with equipment.

Anf the temperatures should not over 90 °C.

Encapsulation and Sterilization Method

1. Remove the motor from the connector immediately after drying.
2. Install the shaft plug of the motor.
3. Encapsulate the dental LED electric micro motor.
4. Sterilize the dental electric motor in an autoclave.

Attention：

• Sterilization method: Autoclaving.
• Do not autoclave the control panel, charger, or motor cables.
• Sterilization conditions: at 134℃ for not less than 5 minutes.
• Before sterilizing the motor, it is necessary to remove it from the motor connector and install the motor shaft plug; except for the parts that cannot be sterilized by high temperature and high pressure, the other parts cannot be sterilized.
• Do not lubricate the motor.
• Do not sterilize the surface with stains to avoid rusting.

Last but not least, the above points should be given more attention in the use of dental LED electric motors, preferably to a dentist or assistant training.
