6 months post sliding genioplasty - am I fully healed?

I had a sliding genioplasty 6 months ago with movements of 6 mm forward, 3 mm down, and 3 mm widening. I recently had a panoramic X-ray done at the dentists office and was wondering if my chin is fully healed? I do see a faint black line where the cut was made and slight dark circle on one side where a titanium screw is. Based on the picture, is the bone fully healed?
