By the way, I wish everyday I have kept my WT. It was the biggest mistake of my life (and I've made huge mistake trust me)
If I had the choice between correcting my class 2 and removed teeth to have surgery, I would choose the first option. Youthful appearance worth more.
Unless you have health issue because of your retrognathia, such as sleep apnea, difficulties to eat properly, don't do surgery, it's my advice.
