Functionality can be defined as “the quality of being suited to serve a purpose well”. The functionality of the dental chair can greatly influence the efficiency of the dentist. Consider this, an experienced lumberjack might spend 2 hours sharpening his axe and be very good at using it, but his son who has a chainsaw is definitely going to able to complete the job faster.


The Delivery Unit

Dental delivery systems come in various formats. Some practitioners might want a customized setup that increases their comfort and efficiency in dental practice. We’ll look at the two most common systems used in dental chairs – Traditional & Continental Delivery Systems. The other types of the mobile dental delivery unit include the Side and Rear Delivery Units.


Continental Delivery Unit

The continental delivery system offers unparalleled ergonomics. This is presented as solution situations when dentists have problems reaching to grab the handpiece they require or when they find themselves caught in a web made of intertwining tubes.


Movement of the Delivery Unit

The delivery unit should have unrestricted and smooth movements in order to ensure maximum ergonomics and longevity. Having a locking mechanism incorporated into the rotating hinge can add great value as the operator can dictate the position of the equipment and instruments in the delivery tray, drastically minimizing the change in posture.


Control Panel

The control panels used in the dental chair have undergone various amendments by different brands of manufacturers. The most commonly included control parameters include chair position, led dental operatory light intensity adjustment, water spray control and speed control for the pneumatic or electric motor. Feather touch buttons are usually included in the dental chair control panels.


Chair Position Adjustment

The dentist is required to subject the dental chair to quite a few position changes. It is a well-known fact chair positioning is a very important aspect in the success of dental treatment as having correct positioning can augment the operator’s visibility and accessibility to the oral cavity.


Chair Movements

The movements of the dental chair should be smooth. While moving from one position to another, the dental chair should not startle or pose any shaky movements. The patient on the dental chair must already have a certain amount of anxiety while being seated and the jerky movements of the chair can add to the fears of the patient.


Foot control

Although the control panel is equipped with various types of functions that can be altered, the use of a foot control ensures better asepsis and can prevent cross-contamination between dental patients. The traditional disc type of foot control allows the dentist to control the amount of compressed air that enters the airotor tubing, causing the air turbine to rotate. They also featured controls to bring the chair back to the zero position.
