As a practicing OMS, the future of our profession is FULL SCOPE.
EVERYONE within dentistry is doing office based oral (not maxillofacial) surgery... Perio took over implants, GPs doing 3rd molar extractions, taking bone grafting courses and doing their own ridge augs, Prostho doing all of their own implants, bone grafting and soft tissue management (vestibuloplasties, etc)
Being well trained in orthognathics, TMJ diagnostics and surgery, and path will make you MORE MARKETABLE within both the medical and dental community. I cannot stress this enough being barely 3 years out of residency. The future and survival of our profession lies in our ability to offer a broad scope of oral and maxillofacial surgical procedures. Its does not lie in the saturated world of T and T practitioners.
I went to a heavy-on-academics residency program but it prepared me extremely well for the real world of private practice OMS (we did pediatric craniofacial, a ton of malignant path, trauma trauma trauma and sleep apnea). I can handle pretty much anything that comes into my office and have a large comfort zone within OMS. The only regret I have was not STRENGTHENING my expansive base of knowledge with additional fellowship training. Again, the future lies in offering a VERY broad scope to both referrals and your clientele both young and old.
