What are the main technical specifications of a dental chair?

The dental chair is one of the components of the dental treatment unit and is divided into two types: mechanical and hydraulic. The mechanical dental chair uses a motor, shoulder peak, and connecting rods to adjust the chair's lifting and rotating movements. The hydraulic dental chair operates by pushing the connecting rods under the pressure of hydraulic oil cylinders, allowing the chair to rise and fall. Dental chairs can be paired with various dental comprehensive treatment units. The dental chair is designed for patients to sit on during oral examinations and treatments, facilitating diagnosis and therapy. It is always used in conjunction with the treatment unit. During oral and disease treatments, to ensure smooth and convenient diagnosis and treatment, the patient's head must maintain a certain posture, and there are also requirements for the patient's seating position.

It is always used together with the treatment machine. During oral and disease treatment, to ensure smooth and convenient diagnosis and treatment, the patient's head must maintain a certain posture, and there are requirements for the patient's sitting position. Otherwise, the efficiency of the treatment work may decrease.

Whether for doctors or patients, there are requirements for the dental chair.Dental chairThe doctor's requirement is to perform treatment work in a correct and natural posture, obtain sufficient lighting, and easily adjust the patient's posture, allowing the patient to change positions to adapt to different treatments conveniently, without frequently changing the doctor's own posture to meet different work requirements. After long working hours, it should not be easy to feel fatigued. The patient's requirement is comfort and safety; apart from the pain discomfort caused by dental issues, there should be no other discomfort. Additionally, there should be a sense of security. The chair must be sturdy and solid, without unexpected feelings of fear. To meet the requirements of both doctors and patients for dental chairs, considerations must be made for the chair's lifting, rotating, and reclining actions, requiring flexible and light adjustments while ensuring stable fixation of moving parts. The usage of dental chairs is very high, especially in general oral treatment departments. At least dental treatment equipment and dental chairs must be equipped to carry out oral disease treatment work. Therefore, the number of dental chairs in oral specialty hospitals has increased.

Any dental chairDental chair, its structure can be divided into two parts: the chair and the support. The chair body is the part that directly contacts the human body, consisting of the headrest, backrest, and seat. The backrest and headrest of the chair body should be soft, allowing patients to receive treatment in a relatively comfortable condition. The support is used to support and adjust the chair body, with several types including foot-operated hydraulic (hydraulic), electric hydraulic, and electric mechanical.

What are the main technical conditions of dental chairs? Let's briefly understand them.

(1) Each lock: The headrest, backrest, support, armrests, and other parts should ensure automatic locking during use.

(2) The height of the floor for the square asbestos is 3360 for the high height and low height.

(3) The weight of the chair body and the height of the chair body.

(4) In terms of power: The lifting speed of the chair should maintain the stability of the chair body’s ascent, without shaking, excessive noise, or jamming. The dental chair can lie flat, sit upright, and the whole machine is mechanically driven. The backrest and seat are controlled separately by mechanical transmission mechanisms, with three types of movements: chair lifting, backrest adjustment, and overall machine reset, controlled by three switches on the south side, each position having a travel switch. The headrest is used to support the patient's head, preventing arbitrary movement of the head to the sides during treatment. The headrest can be adjusted according to the height of the person and the treatment, and adjustments can be made simply by pressing a button. The angle and height can be adjusted. After releasing the button, the position will be determined accordingly.
