The success or failure of a gum graft is more dependent on the skill of the surgeon and the proper selection of the cases to graft.

If there is adequate amounts of attached gingiva (the thick gum) you only need a connective tissue graft. If you re missing it you need a free gingival grab to reform the attached gingiva. Heal.
