Yes...before we do braces on anyone, we want to be sure teeth are healthy and in good shape. In your particular case the diagonal fracture would make it difficult to place the brace on the right spot on the tooth. So getting it fixed first would be helpful. I suggest doing it with composite...
Braces are possible in bone loss case. Force level would be very light in your case. Aligner/Invisalign is a good option because that gives controlled light force. Implant is possible when enough quantity and quality of bone is present.
Simple porcelain veneers or composite injection moulding can be the best solution for you to improve your shape of the peg laterals and improve your smile. I hope this helps Madhuri
