DENTAL TREATMENT ROOM – DESIGN GUIDE

Design Your Treatment Room for Productivity and Health

SIT WELL

Mandal³ determined that the healthiest sitting position is what he called “the upright balanced position”, with an angle of around 120 degrees between thighs and upper body. In this position, the spine retains its natural curve preventing extended pressure on the intervertebral discs.

The dental assistant’s head should be at the same horizontal level as your head while working. If you are taller, the assistant may use a stool with a foot ring to increase their horizontal position.

Please note that the upright balanced sitting position requires a higher position of patient chair, hand instrument table and worktop than the traditional position with horizontal thighs!

SEE WELL

You are able to see all surfaces of all teeth – maintaining a balanced working position – when you combine all working positions between 9 and 12 o’clock with 6 different patient head positions: 3 for the upper jaw and 3 for the lower jaw⁵.

Note that especially the 12 o’clock position is important – meaning that the dental cabinet design must allow enough space for this.

WORK WELL

Studies suggest that working with an instrument bridge placed over the chest of patient is the best way of achieving a good balanced working position while seeing all surfaces of all teeth⁵.

Before and after the treatment, position the instrument bridge on the dental assistant’s side of the unit. This reassures nervous patients, as they will see less of unit instruments when entering and leaving the chair. Further, it is easier for the dental assistant to prepare the unit and instruments for the next treatment.

When the patient is in the chair, position the unit’s instrument bridge above the chest of the patient, with a distance of 30 cm between the tips of the unit instruments and patient’s mouth. In this way, you and your assistant are able to reach the instruments in all working positions from 9 to 12 o’clock, without twisting the body and without looking away from the patient.

THE RIGHT PLACE FOR YOUR HAND INSTRUMENTS

The traditional solution is to attach the hand instrument table to the side of the instrument bridge. Here, the access to the instruments is difficult for your assistant while you work in the 9 o’clock position – and for you if you work solo.

A much better solution is to place the hand instrument table near the patient’s temple. The dental assistant can then reach hand instruments using the right hand – or if holding the suction hose with the right hand, reach the instruments with the left hand crossing the right arm. You can even grab the instruments yourself using the left hand.

The hand instrument table holder should allow for rotation and movement to the sides.

A good solution is the XO Hand Instrument Table. It satisfies all of the above guidelines and fits the majority of dental cabinets. The table is easy to position, and it makes hand instruments delivery much more efficient while reducing health hazards.

WORKTOP DESIGN REQUIREMENTS

In order to work safely and comfortably, the dental assistant needs a worktop at a height of 75 to 85 cm above the floor while sitting in the upright balanced position.

In order for the dental assistant to stay with the patient and reach materials just by rotating the stool, we recommend the following guidelines (right-handed dentist):

The left side of the worktop should be 30 cm from the center axis of the patient’s chair
The distance from the neck rest to the edge of the worktop should be about 20 cm – this ensures that the dental assistant can reach the worktop by simply rotating on a stool
The worktop should be at least 100 cm wide, creating enough space for materials etc.

How to Save Space Without Sacrificing Functionality

Finally, allow at least 60 cm of free space behind the patient chair’s neck in order to allow yourself to work well in the 12 o’clock position.

Tips for creating the ideal dental clinic

The ideal dental clinic is designed with productivity, comfort and ergonomics as the main criteria, as these would naturally result in financial benefits.

Some of the ways to increase productivity are to:

• Minimize the size of treatment rooms allowing you to fit more treatment rooms into the premises
• Enable dentists to treat a patient in one room while the other room is cleaned and disinfected.
• Choose equipment that is easy and quick to clean and disinfect, e.g., units and cabinets with smooth surfaces.

To create more treatment rooms in a dental clinic, you need slim and compact dental equipment. An XO WORKTOP and an XO FLOW or an XO FORM unit can be fitted in a treatment room of only 6 m2. This means you can perform extraordinary dentistry even in smaller treatment rooms, as small as room size 220 cm x 320 cm.

A space-saving design in the treatment room makes it possible to fit more treatment rooms into the premises and saves rental costs.
