Dontknowwhattodo,
So, I just quickly buzzed through your posts. From what you wrote, it looks like you're dealing with issues with asymmetry. Correct?
I'm just saying, at this stage (assuming you're done growing), I'm not really sure the 'why' is hugely important. Are your asymmetries from extractions and/or orthodontics? Maybe, maybe not? I just don't think that changes anything now. When we are done growing everything becomes kind of locked (for lack of a better way to put it). Even some doctors that advocate opening the extraction spaces back up, then placing implants, acknowledge the potential need for surgery, too.
My point is that I don't think we can know 'for sure,' but the good thing is that's not necessarily a prerequisite for what steps are taken next.
Cheers!
