The cheek graft is $500 per side, and I was told it can be done as part of the surgery or without surgery. They use a material called hydroxiappetite. I don't know exactly how it's done (i.e. where the incision takes place, etc). I planned to have a second visit and ask follow up questions.
check augmentation varies from person. some cost $3,000+ depending on how much grafting is needed.
based on the 20+ page FAQ sheet i received from arnett's office after agreeing to the surgery, the cheek graft - or augmentation - is done in steps. think of it as a mold. the hydroxiappetite can be manipulated by surgeons for several weeks after the surgery. this is done to ensure maximum aesthetics results and symmetry. the healing process will alter the shake of your job (duh) and enable arnett/gunson to move the cheek augmentation accordingly.
an implant can rarely be shaved and a botched job requires a new implant or cutting the bone. the real problem is if you aren't staying in SB for several weeks post-surgery, you'll have to rely on your ortho to deal with the shaping.
as many have said before, arnett and gunson are obsessed with aesthetics.
