That is an interesting study (but yeah, a lot has happened for dentistry in the past 10 years). Rotary endo, invisalign, Periolase, Implants, weekend mini-OMFS residencies for GP's.
Based on the study's results however, it seems that the main financial advantage (ROI) for OMFS would be retiring a couple of years early (one year for ortho) with the current average income of a GP owner being in the high $200k's. No?
I am certain that an OMFS would make a ton more than just [FONT=arial,verdana,helvetica,sans-serif] $587,563 .over their career life time than a GP.
On the same note, everyone saying that OMFS routinely do 4 wizzies under sedation in 30 minutes and make a million dollars ... well, for one, maybe. Not all cases will take 30 minutes. I've observed OMFS in private practice and in my limited experience it will sometimes take that long just to induce some patients. And two, have you seen an OMFS schedule? It's not like they're booked 8 hours solid for wisdom teeth with sedation. On a good day, they would probably have 3 or 4 cases like that, but the rest of the day may be a single extractions, post-ops, implant consultation, oral pathology consult ....
Has anyone thought that maybe OMFS, ortho, endo perhaps do better because ON AVERAGE also they tend to be smarter than the AVERAGE GP, and in turn are more likely to make better financial decisions, investments, career choices than most GP's? I guess what I'm saying is if you took any one of the said specialty residents out of residency, and put him/her in a private practice setting, I could argue that they would probably do just as well (if not better) as they would have in specialty practice. It's the decisions you make everyday that create a favorable environment for you to succeed. No one person is entitled to no certain amount of money just because they did one particular thing.
