How to Choose the Best Dental Chair?

The dental unit is the basic equipment for any dental clinic. It allows the dentist to fix the patient in a specific position to ensure proper treatment. The dental unit consists of a dental chair, an instrument holder with various rotating devices, a lamp to illuminate the treatment area, a spittoon and a suction system.

Since the dental chair unit is the most basic investment required by a dental practice- and one which should ideally last for years- there’s no doubt that every clinician would want to go for the BEST dental chair, according to his/her needs.

Significant improvements in the comfort and versatility of the dental chair have been made over the last 300 years. Prior to the 17th century, tooth extractions were often performed with the patient sitting on the floor, their head held firmly between the operator’s knees. Everyday armchairs occasionally served to make dental procedures less awkward and fatiguing. But not until the early 1700s did Pierre Fauchard, French dental surgeon extraordinaire, set a new trend in comfort by consistently getting patients off the floor and onto a chair for an examination or extraction.

What is the difference between a dental unit and a dental chair?

A dental unit is often referred to as a dental chair. We decided to separate these two concepts. The dental chair is one of the components of the dental unit.

Other components may vary depending on the dental unit, but there are general trends. Almost all dental units are equipped with a suction device and an instrument holder for treating patients. These tools are:

  • handpieces: turbines, contra-angle handpieces and micromotors for fast tooth milling;
  • a blower to dry a specific area in the mouth;
  • scalers.

The patient chair is an important part of the installation. All seats are adjustable for seat height, tilt and headrest position.

Other installation elements:

  • a light that allows the dentist to see the patient’s mouth without shadows;
  • suction instruments that allow saliva to be sucked in near the sublingual glands;
  • a spittoon so that the patient can rinse his mouth during and at the end of the procedure;
  • a pedal that allows the dentist to activate the instruments.

All reusable instruments are sterilized after each patient. Many tools are disposable.

How does the dental unit work?

There are several elements to consider:

  • Compressed air supply: Dental units are systems that use compressed air. To do this, they are connected to an air compressor or to a centralized compressed air system . The compressor delivers a pressure of 8 to 10 bar at the outlet of the reservoir, which is too much for dental equipment. According to the manufacturer’s recommendations, the unit should be connected to equipment with a pressure of 4.5 to 5.5 bar. You can, for example, install a pressure reducer with an optional filter downstream of the compressor. Good isolation of the dental clinic is imperative.
  • Water supply: Dental units must also be connected to a water supply for rinsing, cleaning and cooling. Water can cause many problems in dental units such as scale, sand, sludge, rust or chlorine. Biofilms can also quickly form on the inner surfaces of pipes and associated containers. To avoid such problems, the golden rule is to have an easily accessible, clean, and efficient general tap to shut off the water in your clinic. Never rely on old cranes. Ideally, the clinic should have an easily accessible valve that can be turned off every evening. To combat limescale, silophosphate ball cartridges are available in the units, which have a service life of approximately 6 months and they limit deposits.
  • Electrical supply: The dental unit components and instruments used during treatment may require electrical power. These could be micromotors or most dental chairs.
  • Ergonomics: This refers to the ability to move component parts of the installation, such as a chair or tool holder. Research shows that working with instruments placed on a tripod above the patient’s chest is the best option for the dentist and allows the entire oral cavity to be examined. It should also be noted that the dentist’s or assistant’s chair must be below the patient’s chair. In this position, the doctor’s spine retains its natural curvature, which prevents prolonged pressure on the intervertebral discs.

What should be considered when buying a dental unit?

In addition to supplying compressed air, water and electricity, there are three other important elements to consider:

  • Dimensions: The space available for the dental unit determines the number of elements as well as the configuration of the system.
  • Application: Dental services can be different and cover all sub-specialties of dentistry (endodontics, periodontics, implantology, etc.). However, there are special orthodontic appliances available which general dentists may not use. This must be taken into account when configuring the tool holders.
  • Mobility: This refers to the possible need for a portable installation . There are portable dental units that fit in a suitcase and weigh about ten kilograms. They can be equipped with a built-in air compressor for handpiece handling. These units are ideal for out-of-the-office work or mobile dental clinics.

How to disinfect a dental unit?

It is necessary to disinfect the following components:

  • Water: Recent studies have shown that a dental cooling system can contain a variety of pathogens. Stagnant water at night or insufficient maintenance of limescale removal systems promote the development of algae or microorganisms such as fungi, which then form a biofilm. There are several methods for disinfecting water, such as using ultraviolet light to eliminate bacteria and prevent biofilm growth, or automatic cleaning and disinfection systems that treat water with specially designed agents that are dispensed in small doses.
  • Chair: The chair is used by all patients and can be splattered with blood, saliva and other body fluids during dental procedures. If the chair is not properly disinfected, patients and doctors can be exposed to all types of microorganisms, such as herpes viruses, HIV, hepatitis B and C, staphylococci, streptococci, etc. These microorganisms can be transmitted through direct contact with blood or body fluids, or even, in some cases, through indirect contact with contaminated objects. The chair can also harbor vermin like lice or bed bugs. Therefore, it is very important to disinfect it after each use with special products.
  • Surfaces: Antibacterial coatings on the metal surfaces of the dental unit are effective in limiting the spread of bacteria. All surfaces must be treated with disinfectants. Several manufacturers offer dental units that automatically adjust the position of the chair or instruments, thus avoiding hand contact as much as possible and reducing the risk of contamination.

What additional options are there for dental units?

More advanced dental unit models offer additional options such as a video monitor or an X-ray generator.

In the latter case, intraoral x-rays using a phosphor plate provide ready-to-use images in an instant. Additional set-up includes an OPG-Lat ceph machine where panoramic radiographs or orthodontic images can be taken. Several manufacturers offer advanced technology solutions to ensure high contrast and accurate images at low radiation doses.

There are also portable x-ray generators that allow intraoral x -rays to be taken in the absence of a wall-mounted generator.

More and more dentists are turning to digital solutions to further optimize their practice. Thanks to this technology, patients can obtain panoramic, orthodontic or 3D images in almost a few seconds.
