Chin implants come in different sizes, shapes, and compositions. Most are firm, not at all soft like breast implants, or even rubbery like calf or pec implants. If properly placed below the soft tissues (adjacent to the bone), healing forms a scar that encapsulates and immobilizes the implant (which may have perforations that allow tissue to anchor the implant even further). The sensory nerves to the chin, lips, and gums should be carefully visualized and preserved during the surgery, and once healed, your chin feels normal to touch (by someone else--they will NOT be able to tell), and has normal sensation felt by you. Your appearance will be different, and your smile may be slightly altered as well (usually it is broader and more self-confident!), but the implant itself cannot be felt, moved, or damaged. Infection is rare, but more common with an inside-the-mouth incision compared to the under-the-chin scar, which is why I prefer the nearly-invisible but present scar on the underside of the chin.
