The free gingival graft is an age-old periodontal procedure that has long been the gold standard for increasing attached gingiva around the natural dentition. However, whether keratinized tissue is needed around dental implants to maintain peri-implant health is a controversial subject.

Please conduct a review as if you are conducting a systematic review in keratinized Mucosa and dental implants.
