Since in germany hardware removal after a bimax is a standard procedure, I picked up a theory in german forums. Many people claim, that they got even more swollen down after their hardware removal. So of course at first they get more swollen, but after that they face get even more leaner than before.
Seems to me somehow not believable, if they didn't have any inflammation and titanium seems to cause this really rarely.
Maybe somebody can tell her/his experience or provide further information, if there exist any articles about this.
