The surgery plan

My surgery is actually a preliminary plan.Either a jaw (mandible) or both, depends on my under bite measurement after the orthodontic treatment.
So for now, it is just one jaw surgery.
It is call as bilateral split sagittal osteotomy.
The mandible is split bilaterally, which enable the body of the mandible to move inward (for protrude mandible) or move outward ( for short mandible). Then the excess bone is remove. After that is the fixation of the bone, in my case, my surgeon told me that he will put in screws. but i search online and found out some surgeons use metal plates also.
