Why does chin implant cause bone erosion but HA fillers do not?

Question

The filler is placed at the same place and feels just as hard as an implant. How come? And will botox in the muscle over the implant/filler prevent erosion of the bone? And also, is it a higher risk to inject HA fillers over the muscle in the chin? Like just below the skinsurface? I feel that it gives more volume than injecting under the muscle where it often migrates in my case. I have been treated by different certified injectors.

Thank you for this excellent question. Bone erosion beneath an implant is a very uncommon occurrence. Many surgeons have placed hundreds of chin implants and never experienced bone erosion. I have never experienced bone erosion as well. The occurrence of bone erosion beneath the implant is probably due to micro movement of the implant. I prefer to prevent this by placing a bone screw through the implant into the bone. Hyaluronic acid fillers are safe and effective to be used at most levels between the skin and bone. As you know, they resorb and need to be continually replaced. Botox will have no effect on bone resorption.

implants can cause issues because they are burrowed/screwed into bone.  But in general fillers and implants do not hurt the chin bone.  Best, Dr. Emer.
