What is a Dental Chair?
Before we understand what parts are in the dental chair, let’s briefly understand what is a dental chair:
A dental Chair is a specialized chair designed for use in a dental office. It is used to support the patient during a dental procedure, providing a comfortable and stable platform for the dentist to perform their work.
The Dental Chair typically has a range of features and accessories that help to improve patient comfort and support, as well as increase the efficiency and quality of care. These features may include an adjustable headrest, armrests, foot control, light source, suction system, and integrated instrument tray.
Next, let us know the components and functions of common dental chairs.
Parts of Dental Chair and Function
We have marked the main parts of the dental chair for you in the picture below. You can directly view the picture to understand the main parts of the dental chair.
Next, let us understand each part of the dental chair one by one.
1. Dental Chair Delivery System
The dental chair delivery system is a part of the dental chair that helps deliver air, water, suction, and other necessary materials to the patient during a dental procedure. It is essentially a set of air and water tubes, tools hoses, valves, Gas storage bottles, and water storage bottles that are connected to the dental chair and provide a range of functions, such as cooling, cleaning, and drying the mouth, delivering the anesthetic and other medications, and evacuating oral debris. The delivery system is usually integrated into the dental chair.
2. Control Panel & Instrument Tray
The main control instrument tray of the dental chair is another important part of the dental chair. Its main functions are:
- Realize the raising, lowering, and angle adjustment of the dental chair seat
- Control various surgical instruments (such as dental high and low-speed handpieces, scalers, 3-way syringes, film viewing lights, etc.)
- Control the dental chair spit toon and power supply
- Provide instrument trays to place surgical supplies
3. Assistant’s Instrument Tray
The Assistant’s instrument tray is a tray attached to the dental chair that is specifically designed for the dental assistant’s use. It provides a convenient and accessible place for the assistant to store the instruments and materials needed for the dental procedure.
The assistant’s instrument tray is usually equipped with 3-way syringe, strong and weak suction handle, and is connected to the High-Volume Evacuator system of the dental chair to achieve the saliva suction function.
By the way, The High-Volume Evacuator is a critical component of the dental chair as it helps to keep the oral cavity clean and prevents saliva, blood, and debris from obstructing the dentist’s view or contaminating the work area. The HVE is usually positioned close to the patient’s mouth and is operated by the dental assistant using a foot pedal or a hand-held switch. The HVE helps to improve patient comfort, reduce the risk of infection, and increase the overall efficiency of the dental procedure.
4. Patient Handpiece
The Patient handpiece, also known as the “patient-side” handpiece, is a component of the dental chair delivery system that is positioned close to the patient’s mouth. It is typically a small, handheld device that the dentist uses to direct air, water, or suction to the patient’s mouth during a dental procedure.
The patient handpiece allows the dentist to access hard-to-reach areas in the mouth and provides greater precision and control during the procedure. It is an important tool for the dentist as it helps to increase patient comfort and reduce the risk of injury or discomfort during dental procedures.
5. Dental Chair Saliva Ejector
The Saliva ejector is a suction device that is attached to the dental chair delivery system. It is designed to remove saliva and other debris from the patient’s mouth during a dental procedure. The saliva ejector typically consists of a flexible tube and a suction tip that is positioned near the patient’s mouth. When the suction is activated, it removes saliva and debris, keeping the oral cavity clear and providing a better view for the dentist. The saliva ejector is usually operated by the dental assistant using a foot pedal or a hand-held switch.
The Saliva ejector is an important tool in maintaining a clean and dry field during dental procedures, which helps to improve patient comfort, reduce the risk of infection, and increase the overall efficiency of the procedure.
6. Dental Integral Air/Water Syringe
The Air/Water Syringe is a handpiece that is attached to the dental chair delivery system. It is used to deliver a controlled stream of air and water to the patient’s mouth during a dental procedure. The Air/Water Syringe is an important tool for the dentist as it helps to cool, clean, and rinse the patient’s mouth, as well as to control bleeding and wash away debris.
The Air/Water Syringe typically has two buttons or triggers, one for air and one for water, that the dentist can operate independently or together. The flow of air and water can be adjusted to provide the necessary pressure and volume for the procedure. The Air/Water Syringe is an essential component of the dental chair as it helps to improve patient comfort, reduce the risk of infection, and increase the efficiency of the procedure.
7. Dental Chair Cuspidor Parts
The Cuspidor is a basin or sink that is attached to the dental chair. It is used to collect and dispose of saliva and other debris during a dental procedure. The Cuspidor is typically positioned near the patient’s mouth and is operated by the dental assistant, who activates a foot pedal or switch to initiate suction and clear the debris.
The Cuspidor is an important component of the dental chair as it helps to maintain a clean and dry field during the procedure, which improves patient comfort and reduces the risk of infection. The Cuspidor can also be used to rinse and clean instruments between uses, which helps to ensure that the instruments are sterile and ready for the next procedure.
8. Dental Chair Headrest Parts
The Headrest is a component of the dental chair that supports the patient’s head and neck during a dental procedure. The headrest is usually adjustable and can be positioned to provide comfortable support for the patient, regardless of size or posture.
The headrest is an important part of the dental chair as it helps to reduce stress and strain on the patient’s neck and shoulders, which can improve their comfort and relaxation during the procedure. The headrest also helps to maintain a clear view of the patient’s mouth, which is essential for the dentist to perform the procedure effectively. Some headrests also have additional features, such as a cushion or built-in light, which further enhance patient comfort and improve the quality of care.
9. Dental Chair Armrest
The Armrest is a component of the dental chair that provides support for the patient’s arms during a dental procedure. The armrest is typically positioned near the patient’s waist and is adjustable to accommodate different arm lengths and sizes.
The armrest is an important part of the dental chair as it helps to reduce stress and strain on the patient’s arms and shoulders, which can improve their comfort and relaxation during the procedure. The armrest also helps to prevent the patient’s arms from moving or interfering with the dentist’s access to their mouth, which is essential for the dentist to perform the procedure effectively. Some armrests also have additional features, such as a cushion or built-in light, which further enhance patient comfort and improve the quality of care.
10. Dental Chair Foot Control Parts
The Foot Control is a pedal or switch that is attached to the dental chair and is operated by the dental assistant’s foot. It is used to control various functions of the dental chair delivery system, such as activating the suction or adjusting the flow of water or air.
Foot Control is an important tool for dental assistants as it allows them to perform these functions without interrupting the dentist or reaching for a separate switch. It helps to increase the efficiency and flow of the dental procedure, as well as improve patient comfort and safety by allowing the assistant to control the necessary functions without distracting or moving the dentist’s hands away from the patient.
The Foot Control is typically positioned within easy reach of the dental assistant’s foot and can be adjusted to accommodate different foot sizes and styles of operation.
11. Integrated Light Source
The Integrated Light Source is a lighting system that is built into the dental chair. It provides bright and consistent illumination to the patient’s mouth during a dental procedure, which is essential for the dentist to see what they are doing clearly and perform the procedure effectively.
The Integrated Light Source typically consists of a set of lights that are positioned near the patient’s mouth and can be adjusted to provide the necessary amount of light for the procedure. Some Integrated Light Sources also have additional features, such as adjustable color temperature or a built-in magnification system, which can further enhance the dentist’s view and improve the quality of care. The Integrated Light Source is an important component of the dental chair as it helps to improve patient comfort, reduce eye strain and fatigue, and increase the overall efficiency and quality of the dental procedure.
12. Dental Chair Oral Camera
The oral Camera is a small, handheld device that is used in dentistry to capture images of the patient’s mouth and teeth. The Oral Camera is connected to a computer or monitor and displays high-resolution images that the dentist can use to diagnose and treat dental problems.
The Oral Camera is an important tool for dentists as it allows them to get a clear and detailed view of the patient’s mouth, teeth, and surrounding tissues, which can help improve their diagnosis and treatment planning. The Oral Camera also enables the dentist to share images with the patient, which can help to educate them about their dental health and the treatments being recommended.
The Oral Camera is typically positioned near the patient’s mouth and is operated by the dentist or the dental assistant. Some Oral Cameras also have additional features, such as the ability to capture video or zoom in on specific areas, which can further enhance the diagnostic and treatment process.
