Did you do any externships? Is there an ortho program where you're doing your AEGD? Was there an ortho program at your dental school? Is there an ortho program within driving distance where you could stop by and get some face time? That's where you'll have your best chances. Having over-the-top, stellar grades/scores only open doors for you where no one knows you.
I didn't do any externships because I decided I wanted to do ortho pretty late into my 4th year. I have had a little bit of face time with ortho faculty mostly due to ortho treatment at my school. I will definitely try to make it back before apps are sent out. My GPR doesn't have an ortho program unfortunately. Thank you guys for the help!
