Patient Position

I think what sort of inspired me to start this thread was observing a dental assistant at an in-office CEREC training taking a picture of #3, then #30.  She more or less started at the foot of the chair and contorted herself and tried to get both shots from that position with a point and shoot camera.  The pictures turned out OK, but more or  less were on par with an IOC.  The occlusal tables were not in view, and after cropping out stuff, maybe only 3 teeth were viewable in the sextant image.  I noticed the same thing when I went to train my staff, so lets go over where to stand and at what angle to put the patient.

The best way to think about where to stand when taking a shot is to think about the headrest as a clock.  With the foot of the chair being the 12 oclock poistion, the patient’s right is 3 O’clock, the top of the patient’s head is 6 O’clock, and the patient’s left is 9 O’clock.

Chair Position:

I more or less only have two chair positions.  45 degrees for lowers and flat or uppers:

When taking either an upper sextant shot or occlusal, I lay the patient flat and raise them as high as the chair goes.

On the lowers I put the patient at a 45 degree angle and lower the chair so that the patients head is about level to my waist.

    This information is good. However, when you think of who will be taking intranet oral, and extra oral photos and what they will be used for, you think consistency. What is the easiest way to teach consistency ? John Cranham did a video several years ago with the idea of taking the pictures while seated. Check it out….consistency, control, reproducability, better focus and no shake.

      Richard, I don’t suppose you have a link to that video, maybe YouTube or something? I’d be very interested in seeing it, as I have trouble imagining how I would take a full set of photos while sitting down. I simply don’t find it a problem using the positions depicted here, from a standing position. With the proper camera settings, focus and shake are simply non-issues and irrelevant. Since we can’t physically brace ourselves on anything while taking this range of photos, either, I’m not sure how consistency or reproducibility would be improved either, but hey……I love learning new and better ways, too!

      I’m really bummed that I can’t attend a course in CA this coming weekend on advanced photographic techniques with a couple masters of both dentistry and photography. :-(
