Can sliding genioplasty provide 3D chin augmentation: forward projection, vertical length & width?

My natural chin is small, in terms of its forward projection, its vertical length, and its width. I had a chin implant a year ago with a reasonably satisfactory result. However, I worry about bone resorption over time. Also, although a relatively large implant was used, I wouldn't have minded going slightly bigger. I'm wondering if a sliding genioplasty can give me a more dramatic, 3D augmentation with fewer long-term concerns, like bone resorption. Possible?
