Could I get special braces? (photos)

Noticed a gap formed a month ago. Always had straight teeth, friends with braces were always jealous! Veneers are too expensive, bonding is also too temporary for me(as well as veneers). I thought maybe I could get braces that will only specialize between my top front 4. I'd do regular full braces or invisalign but they seem overkill, or unneeded with what I have. I've had these gaps for a month now and they always bring my mood down, and smile less, or hide my smile (more noticeable in person).
