Very often, bone grafting is done in combination with what is referred to as a "Barrier Membrane Technique".
Membranes made out of special materials are placed over bone graft sites to keep out the types of soft tissue cells we do not want and promote the growth and migration of cells which will turn into normal, healthy bone. These membranes are very successful and are used quite a bit these days to promote sound bone formation. The membranes are usually removed at a later date, but sometimes they can be resorbed by the body and disappear all on their own.
