January, 2011 my orthodontist decided it was time to move ahead with my treatment plan. He introduced me to my maxillofacial surgeon and I began a series of pre-surgery appointments. Here are the basic steps of my surgery:
- Split and widen the upper jaw
- Cut and move the bottom jaw forward
- Push the chin outward
A wedge shaped cut in my upper jaw would widen it as it was too narrow for the desired bite. Next they moved the bottom jaw forward, by cutting a section of bone on either side, which would align the teeth for my bite. Then a sliding genioplasty pushes a horseshoe shaped section from the middle of my chin outward. I elected to do the genioplasty because my lower jaw was about to be shifted forward and my chin would diminish without a similar adjustment outward.
All my pre-surgery appointments were to build what is called a splint. The splint was made from impressions of my upper and lower teeth and x-rays and shaped to be the ideal model for my bite. This mold is what they would use to guide my jaw while in surgery, to provide the desired result.
