Years ago, I had a chin implant removed, a sliding genio + revision of the same. This year, i had mentalis resuspension with mitek screws for witches' chin deformity and lower lip incompetence caused by these. I see improvement but my mentalis strain, which the surgeon said would be helped, is still significant. Also, initial tooth coverage has dropped somewhat. Can this surgery be repeated with further Mitek screws to achieve a more complete resolution of my chin problems?
