I was quoted for 18 months and I'm to be getting them off at 13 months...next month! I think the ortho anticipated me needed elastics, which I ended up not needing at all. I didn't need any bite adjustment. It seemed like as soon as my teeth had space, they knew exactly where to go and lined up nicely. A friend of mine, on the other hand was told 18 months and she's going on 2 years now.... SHe's had a lot of trouble with her bite, contraptions breaking on her and gaps not closing.
