The dental suction system is one of the most important elements within a Dental Unit. The first time this concept was discussed was in 1961, when the German manufacturer Dürr Dental made the first dental aspiration system.


This small invention completely transformed the way of working of dentists, who began to treat their patients horizontally instead of vertically. With this device, not only the hygiene of the process was improved, but also the ergonomics of the patient and the professional.

Dental suction system: Brief Definition

The dental aspiration system is one of the essential elements of any clinic or dental practice. Its main use is related to the reduction or elimination of cross contamination between the patient and the dentist through motors and aspiration systems.

Through this aspiration it is achieved that the cloud of microorganisms has a radius of less than 30 cm, which is a smaller average distance than that separating the professional from the patient.

The aspirator is a tube that is responsible for sucking the saliva that accumulates in the oral cavity of the patient and is composed of a cannula and a tube or tube of rubber.

How the dental chair aspiration system works

There are two types of dental suction: wet suction and dry suction.

In the wet suction system no air-liquid separators are placed in the dental equipment, and both the liquids and the air are taken to the suction system. In this system, the suction motor works in dry, but the same device has an air-water separator, more efficient than the one usually placed in dental equipment, which ensures that no type of liquid reaches the motor. The liquids are sent to a drain that must be placed in the engine room.

The dry suction system gets its name because the air-liquid separation is carried out in the dental equipment by means of a centrifugal or decanting separator. In this way, all the liquid is taken to a drain that must be located under each of the dental units of the clinic.

When separating the liquid in each of the equipment, we need a separator and a drain for equipment, but we do not need drainage in the clinic’s machine room, since only dry air arrives in the suction system.

What you should know about the dental aspiration system before equipping your clinic

The first and most important when equipping your clinic with a dental aspiration system is to know if you prefer a dry or wet suction system.

Once you have acquired your aspiration system, it is very important that you take into account its cleaning and maintenance. It should be cleaned every day with a disinfectant to avoid unpleasant odors and also that the system clogs and stops working.

In addition, another of the things that you should pay attention to from now on is the new European regulations on the amalgam separator. As of January 2019 it is mandatory for all dental clinics to separate the amalgam in the dental aspiration. That’s why, in ANCAR you can find appliances that already have the amalgam separator incorporated, making daily work much easier.

A dental unit is the necessary work tool of every dental professional. This dental unit consists of specific parts that include the dental chair, stool, lighting, hydric box, aspiration, cuspidor and other elements that we will explain below.

According to the line, the range and brand of the dental chair, those items will be different and will have specific functionalities. In this article we show you the parts of a dental chair, its advantages and characteristics according to the model:

What parts does a full dental unit have?

Dental chair

We start with the basics. The dental chair is one of the most important parts of every dental unit, both for the patient and for the dentist. In this sense ergonomics plays a very important role.

Each chair is formed by a seat, a headrest, a backrest and armrests. The chair can be a standard traditional dental chair or a knea-break chaire (Series 7). Some things to take into account when choosing a good chair is that it is adjustable, rigid, is made of quality materials and is ergonomic. In this case, the minimum height of the chair is located at 400 millimeters, it has a multi-position articulated head and chair movements can be made through the control pedal and keyboards.



The spittoon is the container that is placed next to the dental chair so you can rinse and salivate during the process. In this case, the cuspidor cup is made with porcelain, it is removable and autoclavable. To this we add that the tap is removable so that it can be cleaned in a much simpler way.

Aspirator system

The aspirator is a small tube used to suction the saliva that accumulates in the mouth or small particles of the cavity. Both the aspiration system and the cuspidor are placed to the left of the chair in the case of right-handed, and vice versa if left-handed. If you are interested in ambidextrous and left handed dental equipment you can find the options that we have available in this article:


The pedal in a dental unit serves to activate the rotation of the different instruments, for example regulating the chair or activating the water of the water group. In the SD 150 model the pedal is progressive and has control of the micromotor through a potentiometer.

In addition, there are also other wireless pedals with Wi-Fi connection, as in the ANCAR series 5. The great advantage is that it is much easier to move, more practical, cleaner and safer, in addition to having a long life of autonomy. The recharges are made every 4 or 5 months and you can work with cable while recharging.

Instrument tray or table

The instrument tray is one of the most necessary and useful tools for every professional. The instrument tray holds all needed instruments for the dentist to work with. The way of working of each professional is different. There are professionals who prefer the continental system or whip, others who prefer hanging hoses or cart.

Intraoral lighting lamp

And finally, we finish the tour of the parts of a dental unit with lighting. The intraoral lighting lamp is another of the basic elements that all dental equipment must have. It is a high intensity lamp that concentrates the entire beam of light inside the patient’s oral cavity to be able to work without any type of problem. Look for yours among the most popular lamps sold among dentists.

Parts of a dental chair: What are its advantages?

Now that we have seen in depth what are the parts of the dental chairs, we will explain what their advantages are compared to other models.

The Series 1 consists of an armchair placed at a minimum height of 400 millimeters, so that intervention in the upper parts is facilitated.

In addition, it has a multiposition articulated head, so that the professional can move it with total peace of mind. We also find that the movement of the chair is also possible thanks to a regulating pedal and the main keyboards and the assistant.

You can choose between several ways of working: hanging hoses (SD175), continental system (SD150), system with dental cart (SD60)

Equipo dental ergonómico

For dental professionals, it’s important to make quick purchase decisions when replacing broken equipment or to take advantage of “limited-time pricing.” While equipment and technology are necessary for doing your best work, they can also be expensive and set you on a constant chase for the latest and greatest tools.
