distraction osteogenesis of lower jaw

#1 Post by lily101 »

Does anyone have any knowledge (or has had) a distraction osteogenesis procedure to correct a retruded lower jaw? The jaw is cut and pulled apart one millimeter at a time tricking the body into believing it has to heal the area. As the area forms new bone the jaw is pulled out another millimeter. Any info would be appreciated. Thanks. :lol:

I had an MSDO done (mandibular symphyseal distraction osteogenesis). However, this was done to WIDEN the lower jaw and doesn't do anything to fix issues related to the sagittal plane (i.e., the length of the lower jaw). That will be done in a second surgery after I've had braces for a while...

It sounds like you are asking about a procedure that would fix an issue related to LENGTH of the mandible. If that is the case, the two procedures that are common from this message board are a BSSO (bilateral sagittal split osteotomy, and is much more common these days), or IVRO (intraoral vertical ramus osteotomy, doesn't seem as popular and I believe requires you to be wired shut for 6 to 8 weeks).

My understanding is that almost all jaw procedures are a type of "distraction osteogenesis". If you were to get your hands on an oral surgery text book, the chapter on DO covers almost all procedures that are done to fix poor occlusions or misalignment of the jaws. All that DO means is that fractures are made in the bones, the bones are diverged either during surgery or slowly via an expander device post-surgery, and new bone fills in over a course of months. DO is simply a biological process, and is also common in other types of surgery not related to the jaws.

If you can post more information about the exact procedure you're looking at, I can provide more information if you are in fact looking for somebody that has had an MSDO.

Good Luck
