Buccal mucosa graft?

Hey, so I have an odd question that I can’t find any answers to. As a cheek biter (stim/ nervous habit), I’m wondering if that would impact buccal mucosa grafts for ul, if anyone knows? The inner parts of my cheeks are pretty scarred so not sure if that makes it more likely to have fistulas or if it means that the graft is not possible. Couldn’t find any studies or documentation on this. Thanks!
