How likely is it for the chin to heal completely to the normal shape after removal? Is it time bound?

I got a chin implant a while ago, and was wondering how likely it is for it to heal to the original shape after removal. I myself feel like for aging purposes it's a better choice and I don't like how it looks, I think a softer chin suits my face better The implant had 1cm of forward growth according to the doctor The clinic doesn't answer my questions and I have an appointment with the surgeon in 3 months to discuss this, however I don't wanna wait too long and remove ASAP
