A 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.
Wishing you confidence and clarity as you move forward,
