The dental chair is one of the dental devices that patients come into contact with the most, and the comfort and safety of the dental chair have a crucial impact on the patient’s treatment experience. If the dental chair has malfunctions or any problems, it will not only affect the treatment effect, but also make the patient feel uncomfortable and unsafe. Therefore, proper dental chair maintenance can improve the patient’s treatment experience and enhance their trust and satisfaction.


In a word, regular maintenance of the dental chair can not only extend its service life, but also improve the patient’s treatment experience. Therefore, dental institutions should pay attention to the maintenance of dental chairs to provide patients with a safer, more comfortable and satisfactory treatment experience.



1.Daily cleaning work of dental chairs

01 Cleaning and maintenance of spittoons

The spittoon should be flushed after each day’s work

Suggestion: Remove the cover of the ceramic spittoon and suction filter, wipe them with wet water with a disposable towel, or clean the spittoon directly with water.


02 Cleaning and maintenance of suction tubes

After each day’s work, remove the suction and disinfect the strong and weak suction tubes with disinfectant.


03 Cleaning and maintenance of cushions

Try to avoid being cut by the patient’s keys and other sharp objects. It is better to wipe it with warm water before using it in winter.


After using it, dilute with disinfectant and purified water, then use a disposable towel to wipe the surface of the cushion with the mixed disinfectant for the first time and wipe with water for the second time.


04 Cleaning and maintenance of the handpiece

The handpiece tube should be flushed after the treatment every time

Suggestion: Please use a dental handpiece with anti-suction function


05 Cleaning and maintenance of suction tube filter

After using it, the suction head connector should be unscrewed,and the suction filter should be washed and cleaned with disinfectant

Suggestion: Clean and change the suction filter every week


06 Cleaning and maintenance of oral lamp

When the oral lamp is cooled, the lamp shell can be wiped. Never wipe the oral lamp shell when it is on.Do not use too much strength to wipe the oral lamp.

The lamp arm is controlled by tension spring, and try not to pull the lamp head back and forth in non-working conditions.

(* Note: Do not use solvents containing alcohol or other chemical disinfectants in contact with the oral lamp.)


07 Cleaning of water filter and air pressure reducing valve

1.Rotate the bottom of the water filter counterclockwise, take out the center filter, rinse with water.

2.Rotate the transparent cup of the air filter counterclockwise to clean the filter element.

3.Remove dirt to prevent parts damage caused by entering the water pipe and valve body, which doesn’t make the handpiece operate normally or have a poor effect.



2.Maintenance of dental chairs

01 Power Off

Always power off after each day’s work


02 Exhaust


    • Exhaust: Turn off the main valve switch after the air in the air compressor is discharged after each day’s work.Otherwise It is easy to accelerate the aging of the air pipe, weaken the elasticity of the pressure switch spring, and directly affect the working air pressure.

    • Sewage discharge: pay attention to sewage discharge, the air contains moisture, according to the local air and temperature, discharge about once a month.

03 Lubrication

Dental chairs are still in the stage of mechanical and electrical integration, so it is necessary to lubricate the motor for about half a year.  (Apply butter to the stretch place)


3.Maintenance of high-speed handpiece


    • Cleaning: There will be debris remaining inside the high-speed handpiece during the work, affecting the speed, use handpiece cleaning agent to clean it after working.

    • Lubrication: The speed of the handpiece reaches 400,000 –1 million revolutions while working, so lubrication becomes important.  It needs to be lubricated once a day which in large workload (Note: When using handpiece cleaning agent, try not to contact the handpiece tube to avoid hardening of the handpiece tube).

    • Air pressure: the air pressure of the working handpiece should be between 2 pressures and 3 pressures, and the new handpiece can be controlled at about 2 pressures during the run-in and use stage.
