The primary function of the dental treatment chair is to put the patient in a convenient position for treatment. Physicians should have easy access to the mouth without being forced to hold inconvenient positions for extended periods of time.
The dental treatment chair should be designed to minimize the ergonomic risk of musculoskeletal problems for the physician, while the dental treatment chair supports the patient adequately and comfortably.
The design of the dental treatment chair sacrifices the consideration of the operator's posture in favor of the consideration of patient comfort, aesthetic appearance or mechanical design, which increases the potential risk of repetitive strain injury.
1. The back should be vertical, do not bend
2. The thighs should be level with the feet flat on the floor, allowing the hips to bear the weight
3. Shoulders and arms are relaxed, do not lift or stretch
Correct posture is best achieved by lowering the dental treatment chair between the legs, working in the 11-1 o'clock position, working on the side that requires more flexion, extension, and leg separation.
1. The narrow and thin back allows the clinician to move closer to the patient without bending over. The legs should straddle the chair without touching the knees and without forcing the thighs too far out.
2. Adjustable headrest to support the patient's head and neck in a comfortable position. It should not extend under the back of the dental treatment chair and touch the doctor's leg or knee.
3. The height adjustment should be able to go down low enough for short doctors, and up high enough for doctors in standing position.
4. There is enough backward tilt range to treat patients in vertical or horizontal position. If necessary, the head can be lowered to below the chest to treat syncope.
5. The armrest should accommodate and support the elbows and upper arms of adult to juvenile patients. Handles and forearm supports should be of convenient size and placement, and dental treatment chair armrests should not restrict physician access or force legs too far apart.
6. Give the patient full body support with comfortable padding and lumbar support, and there are no points that may pinch the limb.
7. Convenient and intuitive control, located on both sides of the dental treatment chair, with programmable preset positions and foot control functions.
8. The smooth outer surface can facilitate disinfection and cleaning, and resist abrasion and chemical deterioration.
9. The reliable mechanical structure has the ability to react and move smoothly when lifting large patients.
10. Knob control, so that the dental treatment chair fixed on the base can better adapt to the equipment or the person in the treatment area.
11. Optional features of personalized dental treatment chairs to meet clinical needs (such as: transmission system, operating lights, water supply, choice of fabric and color, added pads, heaters, massage, spittoon, rolling base, etc.).
Each physician has unique needs, desires, personality sizes, and preferred postures that should all be taken into consideration when choosing a surgical chair.
