How & where does bone resorption happen after sliding genioplasty?

I am not of bone resorption in association with a sliding genioplasty. With chin implant surgery, there is a degree of settling that can occur with 1-2 mm of bone resorption. This can be minimized with the placement of bone screws. Following a sliding genioplasty, there will be bone remodeling at the osteotomy site which is part of the normal bone healing process. I would not expect any resorption of the cortical bone.

Thank you for your thoughtful question—it's great that you're researching this in detail before your procedure.
Sliding genioplasty involves cutting and repositioning the lower portion of the chin bone (genial segment) to improve projection, shape, or symmetry. The repositioned bone is then stabilized with plates and screws in its new location.
Bone resorption, when it occurs, typically affects the edge of the advanced bone segment—especially areas that are no longer under mechanical stress or lack full vascular support. In most cases, this resorption is minimal—usually 1–2 mm—and clinically insignificant. It does not typically compromise the overall result.
There are a few things that can help minimize this process:
Precise surgical technique with good contact between bone surfaces
Stable fixation with well-positioned plates and screws
Healthy post-op healing supported by adequate nutrition (calcium, vitamin D, and protein)
Avoiding tobacco and chronic inflammation, both of which can impair bone remodeling
It's worth noting that bone resorption is a natural part of how the body adapts to changes in structure. Most patients do not even notice it—especially when the movement is moderate and the procedure is well-executed.

Thank you for your question. Interesting that you found that there's 1 to 2 mm of absorption after sliding a sliding genioplasty. After nearly 30 years of providing this procedure, I have not run into the literature concerning that issue nor have I seen that affect the clinical outcomes in my clients. I'm sure there are a couple of milliliters of remodeling but resorption insinuates that this is a destructive type of pattern that can affect outcome. Sliding genioplasty performed expertly for the right client can be a powerful procedure. Clients are ecstatic in my experience after the dramatic changes they see with the procedure.

Best of luck.
