Dental Chair Unit Daily Use, Cleaning And Maintenance Guide (Recommended Collection)

Posted: November 17, 2023

The dental integrated treatment unit, referred to as the dental chair, is an essential medical equipment for oral doctors to diagnose, prevent, treat and operate patients.
The dental comprehensive treatment table is the basic configuration equipment for the treatment of dental clinics, which is a comprehensive treatment equipment integrating water, electricity and gas. At this stage, the dental comprehensive treatment table commonly used in the market is a mechanical chair linkage operation, mainly used for dental drilling, cutting, dental cleaning, polishing and periodontal treatment. The high-end dental treatment table is also integrated with endoscopes, electric motors, ultrasonic teeth cleaning machines, light curing machines, etc.

The daily use, cleaning and maintenance of the dental chair are very important. Proper use and maintenance can not only ensure the performance and life of the equipment, but also improve the quality and efficiency of treatment, and protect the health of doctors and patients. Therefore, stomatologists and nurses should take these jobs seriously to ensure the normal operation and use of dental chairs.

●Daily Use And Cleaning Of Dental Chair

Dental chair is a necessary equipment for dentists to treat patients, its utilization rate is high, the correct daily use of the equipment has a direct impact on the life and integrity rate. Since the dental chair is a device that comes into direct contact with the patient's mouth, cleaning is particularly important. If the cleaning is not in place, it may lead to the breeding and spread of germs, which poses a threat to the health of doctors and patients.
Therefore, the use and cleaning of dental chairs are very important for dental doctors and nurses.

1.Daily pre-clinic check-upe

(1) Open the power switch at the front end of the floor box, observe whether the dental chair and instrument tray are in working condition, and remove the fault in time if found.
(2) Open the water and gas main switch located under the instrument disc, and observe whether the water and gas pressure value indicated by the water and gas pressure gauge meets the working requirements. If the pressure does not meet the requirements, adjust the water and gas supply pressure in time to make it meet the working requirements.
(3) Open the water and gas separator to drain the condensate in the gas supply pipeline (if has).
(4) Check that the functional control panel and pedal of the instrument panel are working properly and that there are no error commands.
(5) Check the rotating joints of the oral lamp, three guns, strong and weak suction to ensure that it works normally.

2.Maintenance after each use

(1)Remove the silicone pad from the instrument tray and sterilize it at high temperature.
(2) After each treatment, remove the contaminated handpieces, wipe the visible dirt in time, step on the pedal to wash the handpieces tube for not less than 30 seconds, use neutral disinfection detergent to wipe the handpieces tube, and step on the pedal to wash the handpieces tube for not less than 30 seconds once again.
(3) Rinse the surface of the spittoon with clean water, wipe and disinfect the inside and surface of the spittoon with diluted disinfectant, and then rinse with clean water.
(4) Strong and weak suction respectively absorb a certain amount of water, clean the strong and weak straws, and then absorb a quantitative neutral disinfectant, disinfect the strong and weak straws, and finally absorb water to clean again.
(5) Use a neutral disinfectant cleaner to clean the surface of the treatment machine, wipe the surface of the patient's chair cushion, the handle of the oral lamp, and the control panel of the instrument tray where doctors and nurses will touch it during surgery.
(6) Press the reset button to put the dental chair in the starting position.

3.Maintenance after work every day

(1) Complete the maintenance steps after each use.
(2) Turn off the water and air main switch under the instrument disc.
(3) Turn off the power switch at the front end of the floor box.
(4) After closing the gas, the gas in the tube cavity should be discharged with the three-use spray gun, so as to avoid the pipeline being in a high pressure state for a long time and easy to aging and rupture.
(5) If the spittoon can be removed, remove the spittoon and thoroughly clean it once a day:
Keep the spittoon in a place where it is easy to clean. Rinse the surface of the spittoon with running water, taking care to prevent water from splashing into the surrounding environment. Place the spittoon in a container of diluted disinfectant, ensuring that the spittoon is fully immersed in the disinfectant. After soaking for a period of time (more than 5 minutes is recommended),wipe the surface of the spittoon with a sterilized cotton ball or disposable towel to ensure that there is no residue on the surface. Rinse the spittoon with water to remove the disinfectant from the surface and ensure that the spittoon is free of residue. Then reinstall the spittoon on the dental chair to ensure proper installation.

●Dental Chair Daily and Regular Maintenance

Dental chair is a collection of gas, water, electricity in one of the equipment, daily maintenance and regular maintenance is directly related to the service life of the equipment and equipment integrity rate. For example, regularly replacing worn parts, checking whether the functions of the equipment are normal and timely processing, etc., can extend the service life of the equipment and improve the performance of the equipment.

Here are some reasonable suggestions:

(1) Operating lights and viewing lights can not be switched on and off frequently, which will shorten the life of the lamp.
(2) Regularly clean the strong and weak suction filter to avoid the accumulation of a large number of impurities deposited in the strong and weak suction filter affecting the normal work of the strong and weak suction.
(3) The water pressure and air pressure must be within the specified range, so as not to cause the burst of the filter and pipeline.
(4) Disinfect and wipe the oral lamp regularly, and remove the handle of the oral lamp for high temperature disinfection.
(5) According to the local water quality, regularly clean or replace the water filter to maintain the quality of water.
(6) Regularly check the transmission components of the patient's chair, and the position of the mechanical transmission should be regularly added with lubricating oil. Electric hydraulic drive to regularly check the amount of oil and oil quality in the tank, when the amount of oil is insufficient or the quality of oil is not good, timely supplement and replace. Pifu drive should pay attention to adjusting the tightness of the belt.
(7) Regularly check whether the instrument connecting arm and the mouth lamp connecting arm are loose or have safety hazards, and adjust them in time.
(8) Regular cleaning and maintenance of the doctor's chair: clean the seat cushion and back of the doctor's chair with cleaning agent; Clean the dirt on the piston rod of the gas spring and wipe a small amount of lubricating oil; The part of the angle adjustment device can also spray a small amount of lubricating oil.
(9) Handpieces maintenance: It is a key component of the dental comprehensive treatment chair, in the process of use, in order to avoid cross-infection between patients, handpieces must also be subjected to high temperature autoclave sterilization. In order to extend the service life of the handpiece, special attention should be paid to daily maintenance: before the first - first use, the injection needle should be used to drop 1 to 2 drops of high-speed lubricating oil into the shaft.Under normal circumstances,the locomotive should be cleaned once a day with cleaning lubricant, and the miniature bearing should be cleaned once every 2 weeks after work. It Should be maintained normal working pressure of 0.2~0.25Mpa; When there is no water, the handpiece can not idle, otherwise it will damage the bearing. When the needle is blunt, the new needle should be replaced in time, otherwise it will also affect the life of the bearing.

●About The Water Filter For The Dental Chair

Many dental hospitals/dental clinics, the dental chair (dental integrated treatment machine) they purchase has been used for about one year, and some even use only a few months, then it begins to leak. The main manifestations are as follows:
1.3-way syringe button water leakage or slow button rebound, nozzle dripping.
2.The water control valve core is stuck, resulting in frequent leakage of handpieces joints.
3.The solenoid valve core impurities stuck, resulting in mouthwash and spittoon water leakage.
4.The water control valve core is stuck, causing the handpieces to stop, the water will delay closing.

Why does the dental chair appear in these situations above?

This is because the general ordinary dental chair has only one water filtration system, and this filtration system can only filter out some of the larger particle impurities in the water, and some of the small particle impurities are not filtered out, and will flow into the water pipe of the dental chair. Another reason is that the pipeline of the dental chair has been washed and soaked by water for a long time, and the pipe wall has produced a lot of scale. Caused by small particles or scale blocking the water valve body of the dental chair. Many hospitals have hired professional dental equipment engineers, and there is no good solution to this problem.

We have a range of dental chairs that were created specifically to address this pain point. This series of dental chairs has a three-stage water filtration system, as follows:
