This must have been an especially challenging edition of the Chairside Photo Hunt because only three of you found all 20 differences. Maybe you were too distracted by the cutting-edge digital impression technology you see me demonstrating in the photo, which was taken during one of the courses I teach on the subject at the Glidewell International Technology Center. If you're looking to pick up some continuing education credits or your interest is piqued by what's going on in the photo, you may want to visit www.glidewellce.com for info on upcoming courses. Thanks for playing!

Here are the results:

First-place winners:
3 dentists found all 20 differences and will receive $500 in lab credit each.

Second-place winners:
15 dentists found all but one difference and will receive $100 in lab credit each.

Third-place winners:
39 dentists found all but two differences and will receive $100 in lab credit each.
