What can be done about Mentalis Dysfunction: Chin Dent after a chin implant? What went wrong that caused this deformity?

I am 4 weeks post a chin implant and full face lift. Two weeks ago a chin dent popped up on the right side of my face. I have read that Botox could help, but I want a permanent fix. I had the smallest chin implant available used. If I have it removed, will I have loose skin on my chin ? What went wrong that I have this deformity ? Any possibility that with time it will resolve on its own ?
