I want to increase vertical length by 10 mm at least. After the surgery and the healing period (6 months-1 year) is complete, do you get back the full feeling of the modified bone that is attached to the skull by plates? Does that bone combine and heal itself with the rest of the skull again or will it be attached to your skull only by plates and screws for the rest of your life? if an implant is used for greater vertical length, would that affect the healing process?
