Chin bone loss after 10 years with implant, what to expect in the future? Do I need a jaw reconstruction? (photo)

10 years ago when surgeon placed a chin implant (silicon) right away it seemed weak. Recently another surgeon removed old and he saw that I have extreme bone loss. He put a new implant in and profile still appear weak. First, is the bone loss was due to an implant? Will the bone loss continue and what are my options ? Any other side deseases I should be concerned about or body areas? Do I need a jaw reconstruction? I hope I can stay with this implant for good. Please share your opinion and what to expect.
