The expanded mesh free gingival graft: A novel approach to increase the width of keratinized mucosa

Abstract

AbstractBackgroundThe importance of an adequate amount of peri‐implant keratinized tissue and attached mucosa has recently been emphasized. This manuscript presents preliminary findings of a novel approach for increasing the width of keratinized mucosa (KM) around dental implants using a mesh free gingival graft (mesh‐FGG).MethodsTwo healthy adults were treated as part of this study. After implant placement, a large edentulous alveolar ridge with shallow vestibule and minimal amount of KM was treated in both subjects (one in the posterior mandible and the other in the anterior mandible) with the combination of an apically positioned flap and a mesh‐FGG. Clinical, esthetic and patient‐reported outcomes were observed at approximately 4‐month time points.ResultsAll sites healed uneventfully after the treatments. In both cases, increased vestibule depth, soft‐tissue thickness, and width of peri‐implant KM were obtained. The patients did not report any accessory discomfort. Four months following the grafting procedure, good overall esthetic outcome was observed with minimal color disparity and graft demarcation.ConclusionsWidth of KM around dental implants can be increased using a mesh‐FGG. Randomized controlled clinical studies comparing mesh‐FGG to conventional FGG and other commonly applied techniques are required to assess the long‐term efficacy of this novel technique in terms of soft‐tissue thickness, width of peri‐implant KM, and patient‐reported outcomes.Key pointsPrincipal Findings: Meshed‐FGG allowed an expansion of the length of the harvested graft. This results in coverage of large recipient sites, increase in height of KM and good aesthetic integration of the graft.
