Is there any way I can get my braces off early, yet continue to make my monthly payments for them?

I’ve currently had braces on for 11 months. It will make a year in May. I plan to leave for the Air Force in May, but unfortunately I can not go into basic training with braces. My teeth are straight due to short time of 11 months, though I still have til November of 2019 until the braces come off, and I’m making payments for them. Is there any way I can get them off before May but continue my payment method each month until they’re paid off in November?
