What would be best for my problem? Significant midface deficiency (Photos)

I had Lefort 1 upper jaw surgery couple years ago because I was born with a very recessed maxilla and had a bad underbite. I realize now I still have that sunken in, flat, sad look when face is neutral. So I would like my upper maxilla above the Lefort 1 line to appear flush with cheekbones thus hopefully removing the downward shadow lines gap that is present. I roughly present what I would want. I believe my best route would be submalar implants. For implants, which material lasts best?
