The presence of an adequate zone of keratinized gingiva has been considered as critical for maintaining marginal tissue health and preventing continuous loss of connective tissue attachment for many years. However, opinion concerning what could be regarded as an adequate or sufficient dimension of gingiva varied. While some authors suggested that less than 1 mm of gingiva might be sufficient, others claimed that the height of keratinized tissue should exceed 3 mm. Enhancement of peri-implant soft tissue is an essential factor in implant survival. The ultimate goal of periodontal/restorative team is to provide an environment for crowns with long-term successful results. One essential goal of periodontal therapy is to make an adequate zone of keratinized gingiva. Establishing an adequate zone of keratinized gingiva to firmly attach to the underlying periosteum and osseous tissues is critical for long-term functional and esthetic results so that implant soft tissue-implant interface can be established. Free gingival graft (FGG) can be chosen to correct soft tissue defects and provide optimal peri-implant health in order to increase the long-term prognosis of implant reconstruction. Several cases are presented here to illustrate clinical management of soft tissue by increasing the zone of keratinized gingiva using FGG.
