Wound would not heal after 6 months chin implant. Is my implant healed? (Photos)

Rough skin appeared after 1 month below the lower lip. The opening for the chin implant would not heal for 6 months, staying red and no scar. The picture shown here is after 2 yrs, the rough skin persists and the wound is in grey indicating healed. When pinching the chin area, it hurts. Occasional sharp nerve pain. and itch still. My implant teeth #29 #30 failed and had to re-do and of course with lots of antibiotics. Is my implant healed?
