A-dec 500 Dental Chair

Superior Patient Experience. Optimal Access.

The A-dec 500 dental chair provides gentle, supportive comfort that puts your patients at ease for a positive experience that sets you apart. It ensures patient comfort even during long procedures.

It also allows you to get close enough to the patient to maintain a healthy posture, preventing pain and discomfort.


The New A-dec 500

Sleek, yet supportive. Unassumingly responsive.
Predictable and intuitive. Experience the next level.


Superior Care

Precision hydraulic motion allows quiet, gentle stops and starts during patient positioning. Coupled with the virtual pivot, which synchronizes movement with the natural motion of the patient, there’s no readjusting when the chair is reclined or returned.

Whole Body Patient Support

The stingray-shaped backrest fully supports the patient’s back and shoulders, while one-piece quilted upholstery feels remarkably plush (sewn upholstery).

Sturdy, multi-position armrests solidly support patients for easy entry and exit.


Optimal Access

The A-dec 500 dental chair's ultra-thin backrest and slim-profile headrest provide more leg room under the chair so you can position the patient low enough to gain access to the oral cavity while maintaining an ergonomic position. 

A-dec 500 Dental Chair Features

Thin, flexible backrest. The ultra-thin back allows you to work in a comfortable position—legs under the patient, elbows at your side.

Double-articulating, gliding headrest. Access angles can make the difference between a long day and a good day. The headrest adjusts on the fly with the press of a lever for an optimal view of the oral cavity.

Ergonomic baseplate design. Flip the patient chair armrests out of the way, and the shape of the baseplate allows you (and your team) to roll in closer to the patient and work in a comfortable, natural position.

Sturdy, multi-position armrests. Supports patient weight when they need it, and moves out of the way when they don’t.

Toeboard tilt. When the dental chair reclines, the toeboard imperceptibly raises a full 9” for a gentle cradling effect. All your patient feels is relaxed.

Low base-down point. Allows the doctor, regardless of height, to work comfortably.

60º swivel with brake. Allows 30º rotation on each side of centre.


A-dec 500 Radius Operatory Package

The Radius delivery and support modules quickly and easily rotate around the dental chair for complete left/right compatibility.

Additional Dental Equipment Options

Dental Lights

Dental Lights

The A-dec 500 LED dental light brings a lot to your practice. A clearer view of tooth surfaces. Reduced eyestrain. Less fatigue. 

Monitor Lights

Monitor Mounts

Monitor mounts pivot to accommodate viewing from a variety of patient positions. Increase case acceptance when you incorporate the use of an intraoral camera with a chairside monitor.

A cabinet-mounted monitor at 12 o’clock makes an excellent choice for patient record keeping and practice management applications. Ceiling, wall, and central/side cabinet-mounted monitors are ideal for providing patient entertainment in either seated or supine positions.

Assitant's Instrumentation

Assistant's Instrumentation

Choose the A-dec 500 12 o’clock assistant's instrumentation with round work surface or the chair-mounted A-dec 500 assistant's instrumentation with short- and long-arm options.
