Forehead repair after FFS. Would bone cement be helpful?

Hi! I did frontal bone reduction a few years ago. I can’t identify with it. I tried face fat transfer, but it didn't work. I want to try with bone cement because I think it would give me a structure similar to the bone. Is bone cement a good idea for restoring my forehead? I would really appreciate any opinions, ideas or suggestions of doctors in Europe for my problem. Thank you!
