I have that open "bald" area around the abutment and did not get the skin graft. I would imagine that would just be another chance of small complication~ if the skin graft doesn't take. This seems more for appearance reason.
Is your hair real short, and did the doc give you the option, or did he just say he was going to do a skin graft.
Like others have said, we haven't seen this at all on the forum....Not too late to ask more in depth questions if you think you don't want or need the graft. You should be able to call and make appointment with either the doctor or one of his residents if you wish.
The main goal IMO is to keep the abutment area clean and infection free. Having a skin graft there would make it more confusing and difficult
Anyway, just make sure you feel comfortable with what he is going to do. It is not too late to cancel the graft, if you so desire.
Let us know how things go!
