Subject: Finishing with Class III molars


I am aware of the trend to increased rotation or offset built into our upper molar brackets. However I am also aware that in Class III cases and also in cases where premolars have been extracted only in the upper arch (no lower extractions), this rotation is not desirable. Could anyone recommend a rotation value to use in these cases? Would it be zero degrees? Would the 2nd molar have the same rotation as the first or would it benefit from slightly more? I'm fascinated to see what you all come up with.

Hi Charlie:

Good to hear from you too.  At this time, I am direct digital and have been using digital models since they started (7 years ago or so).  I did not raise my fees on the direct digital as the money saved on chemicals and the efficiency at which x-rays can be taken has offset the upfront costs.  We see about 45-50 patients a day, so taking a pano in 30 seconds is pretty nice when you want one on the spot.

The cost of my digital models is killing me and I have raised my fees on records to cover this cost.  At $100+ a set (initial and final), this is at least $25K a year in expenses for the models alone.  This is where I see the benefit in having the iCat.  If the machine cost another $100K over the direct digital, I will cover the cost in 4 years of not taking the digital models.  I could always stop taking digital models now, but once you have used them for as long as I have, going back to plaster is difficult.  I still take progress models in stone and make a 2nd set for my GPs to review on my IDT patients. 

Having said this, I can think of a few other things that I would rather have before buying a CT scan for the office.  When the machines are faster, the software is out of beta and the costs come down another 25%, I will be the first in line.  In the meantime, we have a GP and two oral surgeons in town with machines in their offices.  If I need one, I can always refer my patients out and still get good at reading the pics on someone else's dime.

Still loving Ortho in Stuart, Florida.  Let me know when you are back in town for a visit.
