The A-dec 500 Dental Chair has set dentistry's hallmark for treatment room comfort, reliability and performance, since its original manufacture in 1996. The 'legend' that is the 500, gives you optimal ergonomics supported by a full range of integrated possibilities.

The 500's Treatment Centre has been redesigned in 2019 and is now known as the A-dec 500B.  Now with a completely new delivery head for traditional hanging or continental, the dental chair is built to provide even more flexibility for integration in the future. Other outstanding features of this unit include:

Designed to look after you and your Health

The ultra-thin flexible backrest and the ergonomic baseplate allows you to work in a comfortable working position, whether working from behind or from the side. The chair features a 60-degree swivel with brake and the chair raises to a high point of 800mm which is ideal for those who like to work in a standing position.

Outstanding Level of Patient Comfort

The 500 has always been known for its exceptional level of patient comfort.  The precision hydraulic motion cradles your patients and ensures a smooth and assured ride. The pressure-mapped tailored upholstery ensures support across the whole length of the body and the double articulating headrest enables comfort and positioning for the dentist.

Choice of 4 Delivery Options

A-dec offer options for delivery to suit the way you and your team work, within the space you have. Opt for the Traditional Hanging or Continental delivery on the chair. Alternatively, talk to our surgery design team about a rear 'duo' system or side cabinet mounted system.

Incredible Lifting Capacity

Now with an increased weight capacity the chair now holds up to 35 stone (227 kg), more than any other on the market.

The A-dec Difference

The quality of your dental equipment directly impacts profitability. Dentists consistently rank A-dec dental equipment as the highest in quality.

A-dec's attention to detail is second to none.

A Choice of Upholstery

Ambidextrous Delivery

Flexibility for your surgeries ensure the treatment centre can easily be changed from right to left and left to right.

Taking Continental Rod Type Delivery to the Next Level

The longer instrument tubing on the continental version reduces in-procedure resistance and fatigue. With a side-to-side movement also handpieces remain balanced without any pull back.

Large Working Area

The new delivery can hold up to two trays and there is a central put down also.

LED Coolant indicator

When the handpieces are lifted out of the holder, the indicator will show where to replace without second-guessing.

One-handed Adjustments

Grasp the handle and the flex arm brake automatically releases, allowing you to effortlessly position the delivery system with one hand.

Adjustable Handpiece Holders

Ergonomics are considered with every aspect of the chair design, including the ability to tilt the angle of your handpieces for easy grip and can be returned easily. 

6 Position Control Head

With up to six outlets on both the traditional and continental systems.

Flexible Integration to support you now in the Future

Being able to upgrade your unit with the latest technology is crucial. One example of this W&H's Advanced Air. This award winning hadpiece is one of the world's first air high-speed handpieces with an adjustable bur speed and constant removal rate - even with increased pressure.

Exceptional illumination

Dental Decontamination Room Design

”I am delighted to recommend Hague Dental Supplies. The whole Health Centre has undergone a total renovation within the 110-year-old Grade II listed building and the Dental Surgery renovation was an integral part of this. Fortunately, our location was only five miles from the Hague showroom and I was able to view the extensive range on several occasions. All Hague staff worked to a high standard of professionalism in the design, construction, and installation of all the equipment which was carried out within the agreed timescale.”

Victor Wiffen, Christs Hospital School
