Dental Chair Parts

When a dental chair is broken down until it is no longer a chair, and now just dental chair parts, one will see it is quite a complicated piece of furniture. The chair can be explained best if we separate it into two parts. The pedestal is the bottom half and the chair itself is the top half. There are 15 major components to this important piece of equipment, some of which break down to a more detailed array of parts, switches, toggles, etc. These chairs are very functional as well, and have been evolved throughout the years. They are now much more comfortable than the earlier versions that resembled more of a torture machine than a place to comfortably rest.

The material they use to actually cover them has evolved quite a bit as well. For starters, they were once made of wood, and were not covered with any type of fabric or material at all. Nowadays they are made with an antibacterial material that is designed specifically for ease of cleaning and disinfecting. This material will reduce the risk for infections and other germs to be spread from one patient to another.

The top portion has several dental chair parts that when combined help in its operation and efficient functioning. There are two sets of switches, the Doctor's control switches and the Assistant's control switches. Moving downward as we examine the chair we will notice the back assembly, and then arm rests, and the seat assembly. The more complicated dental chair parts involved in the upper portion are the seat motor assembly, back motor assembly, and the cradle assembly. These three parts are located just under the actual seat.

In discussing the bottom section and the components that make it work, it gets quite complicated. The first part found upon moving downward is the mount assembly. Then, just under the mount assembly is the pantograph arms. These look more like an accordion style coat rack for the wall. Covering the pantograph arms is the bellows assembly. There is a highly complicated base motor, which is also known as the lift motor. There is a chassis that sits above the pedestal footswitch. Lastly, holding the chair firmly in place is a large, heavy, round floor plate. These are all the major dental chair parts involved in the lower half of the unit.

As one can see, the basic dental chair parts that make up the entire unit from top to floor plate can become quite complicated as it gets broken down. It can be dissected much further, and gets much more complicated as one does so. They have certainly come quite a long way since first being made from wood. They are made to be able to raise up, lower, rotate, and recline, making them much more comfortable than the first wooden ones as well, not to mention the fact that the movements assist in helping the dentist to perform procedures comfortably. As you can see, each component is vital in making this the functional unit it is today.
