Am I a candidate for lingual or Invisalign braces, and do I need top braces to fix bottom teeth? (photos)

I had braces in high school, and was given a top retainer to wear every night and a permanent bottom retainer adhered to the back of my bottom front teeth. My bottom teeth have totally moved into a slant. I really don't want to have noticeable braces (again) and am hoping a clear or hidden set of braces is an option for me. Would I need to get top braces too? Also, would removable bottom retainers prevent this from happening again? Thank you.
