Modifications in the Free Gingival Graft Technique: A Systematic Review

Abstract

Free gingival grafts (FGGs) have developed beyond covering exposed roots to improve the width and thickness of gingival tissue. While traditional FGGs have shown a high success rate and are easy to apply, they have some drawbacks, such as potential aesthetic concerns and bulky appearance. Recent advancements in FGGs have been explored, with different modifications proposed to overcome these limitations, including partly epithelialized FGGs (PE-FGG), gingival unit grafts, and epithelialized subepithelial connective tissue grafts. This systematic review aims to evaluate published case reports that discuss the utilization of modified approaches to FGG treatment and their outcome.
