Jaw angle implants done external rather then intra oral. Will scarring be bad? Risks? And photo's of past patients scars?

I had jaw implants twice now and they have got infected both times on each side intra-oral. I really like the look but don't want to risk intra-oral again. I am thinking of having then re-done external with incisions on the neck. I was wondering if any doctors had experience or advice about jaw angle implants done this way and/or pictures from past patients with the neck scars.
