I believe it's silicone. The doctor (Fred Hackney), PS, has since taken medical retirement...so he's not exactly available for the "bone" I'd like to pick with him. I was told pre procedure it would be fixed with screws, and that it wouldn't be a button implant...but now I honestly have no firm frame of reference with which to go on.
Yes, my eyes are a bit close. Have fractured my nose several times on the ridge, so that too has given the illusion of closer set (least I think).
As for the venders, they have just created a bigger overbite, i.e. the ortho who designed them gave them a bit more length/size to give me more tooth display. Just feels disproportioned. Nothing so much categorically -(wrong) with them. Also, my teeth were grinded down, so, it's forever; perhaps I'm just little bitter about the entire outcome. It very well might be that the impant is creating more issues than I'm currently able to grasp. Seems like the implant is gripping real close to my teeth, its created an upward curling on my bottom lip; very strange.
Don't know about the sculpta, looks like a temporary procedure of considerable replacement intervals.
So, sliding genioplasty. How much chin bone does the doctor need to be able to create/construct a nice vertical improvement. Read a little about this chin wing osteotomy procedure that seems to be gaining popularity.
