The All-on-4 technique is a graftless solution so that it's designed to avoid bone grafting.
So the big four on upper jaw, for example, there are cases where when we get a CT at the console, there's no bone, or there's very little bone volume or no thickness in the upper jaw.
There's a solution to solve that (also graftless) which is abutment implants, which is implants that go into the cheekbone.
Abutment implants are performed by an oral surgeon, not myself. This is a very good alternative for someone with no bone on the top jaw at all.
On the lower jaw, it's very rare that there's not enough bone for the All-on-4. I can't think of many, if any, we've not been able to do.
So on the top jaw, it shrinks more horizontally, whereas the lower jaw there's always some vertical bone for the procedure.
There's no plan B on the lower jaw - you can't just use abutments. Using abutments is a common, routine solution for patients with no bone on the top jaw.
