Hello, I am 21 years old and never got any orthodontic treatment. I have a dental class II div. 2 malocclusion. I visited 3 invisalign practitioners and got 3 different treatment plans: - 1.5 years of invisalign + IPRs on lower arch - 15-18 months of invisalign + 4-6 months of regular braces - 2.5 years of invisalign with elastics or 1.5 years with braces (extraction of all 4 wisdom teeth and IPRs anyway) What is your opinion? Thank you for your answers!
