I think you are correct that ortho would be difficult due to the nature of the treatment plans. While not impossible, logistically it would be a challenge with recall and different doctors on different trips.
We have been doing volunteer dental and medical work in Baja California for a number of years. Most of the work we do is fillings, extractions and cleanings. Some endo. We are lucky to have a lab technician that comes with us and makes dentures/stayplates at the clinic. There is an orthodontist that comes with us and mostly takes impressions and treats the removable patients. None of us would care if he wanted to pull teeth or do some restorative work but I think it is his level of comfort and he is just happy to be involved.
