I've read that the implant can erode the bone due to micromovements due to not being fixated by a screw. My surgeon screws the implant in and said there should be no erosion.
I really like my result from the genioplasty but after all the morphs I created, I became fixated on achieving my ideal chin. Even though I'm just short, I would really like to get an implant so I can achieve my ideal chin. Also heard that predicting the results can be hard as the soft tissue movement is unpredictable.
I'm not sure yet but I guess even if I wanted to, I have to wait 6 months as he won't perform the implant until at least 6 months post-op.
