Installation and Maintenance of Dental Units

Dental unit is a basic equipment for dental clinics, which is a comprehensive treatment equipment integrated with water, electricity, and gas. The dental units currently available on the market are usually motor and chair linkage operated, mainly used for drilling, grinding, cutting, cleaning, polishing, and treating periodontal diseases. High-end dental units also include endoscopes, electric motors, ultrasonic cleaners, curing lights, etc.

Installation of dental units

The reason why the installation of dental units is mentioned first is mainly because the scientific installation largely determines the frequency of failure in daily use.

First of all, the installation of dental surgical equipment treatment chairs depends on the initial design conditions of the clinic, which mainly involves factors such as upper water, lower water, power supply, and negative pressure signal lines. If these factors are already collected and fixed under the dental chair during renovation, a dental unit with a built-in ground box should be used. If this condition is not available, an external ground box dental unit must be selected, otherwise normal installation may not be possible.

Second, the basic dental units on the market are pre-installed with side cabinets and seats when they arrive, and on-site installation of dental chair cushions, lamp poles, and headlights are required. dental units with endoscopes planned to be configured must inform the manufacturer to reserve endoscope crossbars and power supplies before ordering. This not only saves the difficulty of installation but also makes the dental chair more integrated and beautiful after installation.

Third, the connection of water, electricity, and gas. The water inlet and gas inlet pipelines must be connected to an eight-character switch valve, which is convenient for the maintenance of the dental facilities treatment chair in the future and is also for safety considerations. There is a case where the absence of this valve caused the clinic to be flooded and had to be closed for renovation.

Maintenance of dental units

The daily maintenance of dental units mainly focuses on the following aspects. First, ensure the cleanliness of the gas and water supplied to the dental units to the greatest extent, such as water filtration and gas injection (as described in the installation section). Second, regularly clean the strong and weak suction filters. Since impurities may settle in front of the filters during daily use, regular cleaning is essential. Third, it is recommended that nurses raise the dental chair to a high position before leaving work and turn on the sink switch to rinse for more than 15 minutes. Remove the strong and weak suctions and place them in a water container, and use the negative pressure of the strong and weak suctions to repeated flush them a few times. Fourth, avoid splashing water on the foot switch to prevent short-circuits caused by foot switch control.
