About two years ago i had my jaw broken in an attack, i was left with an open bite, i want to fix it now?

before the attack i had no open bite, my teeth were normal, had braces as a teenager and all that, after the attack i had surgery , a plate put in and my jaw wired for 4-6 weeks as it was fractured in 2 places, after it i was left with an open bite, teeth come together at th back fine but there is a gap at the front between my bottom and top teeth. braces would be long and expensive and the orthodontist gave no promises it would work, the surgeon who originally operated, and has a good reputation said just leave it and move on , but recently i had a check up and another surgeon asked me about it and i told him how the other surgeon didn't advocate it and was of the mentality was to much hassle and the gap wasn't that big etc. the 2nd surgeon said no it wasn't a big deal and would take a couple of months maybe to heal up etc. i don't know what to do , has anyone any advice, if i knew it would work or has worked for someone that would help. also the gap is about 2-3 cm, also the surge would be free through my health insurance ,thanks
