Would braces in the lower arch be enough to correct my teeth? (Photos)

I had braces 10 years ago, and due to the fact that I stopped wearing my retainer because I used to grind my teeth at night with it, my teeth have shifted. My lower teeth are proinclined, probably because of the lack of space and maybe because of the eruption of the third molars after my braces treatment. In this case I think that IPR is necessary and I was wondering I braces in the lower arch, would be enough because that is my main concern. I don't have any habits like lingual interposition or atypical swallowing. Many thanks!
