I don't believe there are many GPR or AEGDs heavy in ortho, especially GPRs as they are usually geared towards more hospital-based dentistry. I've found they mostly give experience in doing more in-depth molar endo, dent-alveo OS, or implants, but not as much ortho.
Maybe one question you may able to ask is does the program also have an OMFS residency and/or do they do orthognathic cases.. that would likely require an ortho side of treatment.
Have you considered an ortho fellowship at a program with an ortho residency? Usually those carry more weight if you really are gearing towards ortho. Downside though is most are "pay" rather than "paid". Used to have limited options for fellowships, now there are many programs that have fellowships, just have to evaluate if they are worth it or not.
