Placing computer monitors in the treatment rooms so that both the patient and the dental team can use them is a challenge. If your dental chair/unit has a light pole the obvious solution is a pole mount. These work, however they are less stable than wall or ceiling mounts. Every time the light or chair is moved the monitor can shift. They are also often in the way when seating or dismissing the patient. The dentist may not be able to reach the monitor or will have to reach way across the patient to get it.
There are pole mounts from general supply companies like ICW and Ergotron, or from dental equipment manufacturers. I will leave it to experienced dental shoppers to figure out which is the most expensive.
