I stopped visiting the forum a few months ago when I thought I had put it out of my mind to do the sliding genioplasty. I just needed some space to clear my head, make some financial moves, and get my act together. Now I'm in a better spot-good health, good head, good heart, etc.

Previously, I had 3 consults with max/fax surgeons, and one was a skype. It's peculiar, how they all relay a slightly different version of the same information. But, basically what I have going on is a bite in which the lower teeth "bow out" to compensate the upper teeth. My right front tooth is slightly protrussive, and I have a minimal overbite. I believe they referred to it as "over-jet."
Now at age 35, after a night in my retainer, when I awaken my teeth don't fit together at all. I wear the retainer so my front teeth don't start bucking out too much, but when I do, the back teeth don't fit anymore. After removing the retainer, say, after 4 hours or so, things have moved back into place and my bite 'feels' normal/normal for me, again. So, I can physically tell that something has shifted with my teeth. And I don't know if all this shifting is good for me or not. I have some gum loss on the bottoms. Between gum loss and my teeth feeling funny after wearing the retainer, I am feeling like it's time to go into braces again in October when insurance kicks in. Something I recall from the last visit in October with the orthodontist was that he said the plan of care might include removing 2 teeth from the bottom, pulling them back, the cutting the lower jaw to bring it up into correct position with the upper. He did however say that the amount of advancement would be minimal. Then again, he's not the surgeon and I know those guys have to work together.
So, how common is a 2-3mm advancment done? I am definitely doing braces again, one way or the other. I hate how my teeth feel, like my front teeth push up against my lower lip and they fit together with the bottoms like they "bow." Like a clam mouth, if that makes sense. Is there such a thing as a case that is "too simple to bother with?"
