What are the symptoms associated with chin / jaw implants falling out of the muscle?

When we place chin implants, they are placed into a precise pocket on the bone. Additionally we suture the bottom of the implant to the lining of the bone so they should not shift. Shifting or misalignment is possible, however, this is rare. I hope this helps, and thank you for your question. Sincerely, Dr Joseph

Chin implant is placed underneath the soft tissues of the chin, just over the bone. In time it is enveloped in thick scar capsule which does not allows movement. For these reasons displacement and protrusion of implant is not likely. Hope this helps.

I do a lot of chin/jaw surgery. We do implants under the muscles always. I've never seen an implant move or sag once placed. These can be placed right in the office with local anesthesia typically.

Your question lacks proper context
I’m not sure if anybody is going to give you a satisfactory answer based on your post.
Implants typically don’t move from there original placement guy.
Some degree of bone erosion can happen from the pressure of the implant.
If you’ve had a plastic surgery procedure and have concerns, I suggest you follow up with your provider.
Best,
