Post Jaw Surgery Wrong Occlusion. Can't Bite?

It is difficult to answer your question since there is not a lot of information given.  I am assuming the jaw surgery you write about is the surgery to repair your jaw fractures and not orthognathic jaw surgery.  Usually when a jaw fracture is repaired, an oral and maxillofacial surgeon will wire your upper and lower jaws together to place your teeth in the correct position , then they place the plates over the fractures to hold them together in the proper position for healing.  If your jaws were not wired together during surgery this would account for this issue.  If they were wired closed, your fractures may have been severe and it was difficult to get your teeth aligned.  Speak to your surgeon regarding this issue.  IF it was not a board certified oral and maxillofacial surgeon who performed the surgery, seek the advice of one.  You may require orthognathic jaw surgery to correct the problem

Sounds like your fractures were repaired but the occlusion was not taken into consideration? Without looking at your complete notes, it would be hard to make a definite diagnosis, but you would probably need to get either orthodontic treatment to correct the malocclusion (for minor malocclusion such as slight openbite and crossbite) or a revision surgery with an oral & maxillofacial surgeon (for major skeletal discrepancy). Good luck.
