The answer is simple: it's a matter of dental ergonomics.
The Dentist's Perspective
For Drs. Johnson and Risbrudt and their hygienists, the difference in chairs is important for a few reasons:
- The headrests and narrower shoulder areas allow for better maneuvering around you during a procedure, keeping things moving during a longer, more complex operation.
- Height adjustment on the chair allows the dentist to sit comfortably and work without having to strain upward or downward.
While you only spend a few — maybe twice that at the maximum — hours in the chair vs. the thousands of hours the dentist will spend maneuvering around the chair, we nonetheless bought these chairs with your comfort in mind:
- Adjustable head/neck rests ensure that you're never supporting the weight of your head or contorting yourself to let the dentist get to whatever he's working on.
- Lumbar and pelvic support mean that you won't get up with a stiff back no matter how long you've been sitting — and even if your muscles do start to feel a little tense, the built-in massager will take care of that in a hurry.
- Highly adjustable head and footrests allow us to adapt our chairs for almost anyone (though if Sultan Kosen comes back for another visit, we'll probably still need a special chair for him.)
