How to bring my jaw forward in a non-surgical manner? (photos)

So i got my braces about two and half years ago. Since then i realised changes to my facial structure. The lower jaw fell back as a result,my chin has recessed ,my face elongated.I extracted 4 of my teeth. I did not start with an overbite. Can anything be done for my jaw to move forward in a non-surgical manner ? Or will my jaw be back into its place if i take off the braces?I am 16.
