Here is the breakdown at UMD Baltimore:
~135 students per class (so 270 D3/D4)
~90 staffed chairs in clinic
~2.5 hrs per clinic block
M/W/F am/pm : D3/D4 in clinic
T/Th am/pm : D4 ONLY in clinic
W/Th evening : D3/D4 in clinic
When I say D3/D4 are in clinic, what I mean is that all students are allowed to fight for clinic chairs. With ~270 students battling for ~90 chairs, it is a bloody freaking battle.
We do all of our own scheduling. We find an open chair in Axium, ask pt if they can make the appt, then request the appt in Axium....and pray that the receptionist chooses to give us the chair instead of the other 10 students that also requested that same chair.
In terms of lab work, I can't comment much because I haven't done much. We don't do our own casting. We do our own custom trays. We set our own denture teeth. Cerec is available but doesn't seem to ever be used.
About 1/3 of students are assigned to "block" on any given day: pedo, OMFS, urgent care, screening, geriatrics, special pt, etc. It's promoted as a learning experience, but everybody knows that it's a way to get 1/3 of the class out of the clinic each day...to lessen the appearance of a gigantic chair shortage.
Students do all of the extractions during OMFS block.
