Comparison of Two Screw-Retained Free Gingival Grafting Techniques.

Free gingival graft is a predictable technique for increasing the amount of attached gingiva and root coverage; however, its use is limited for cosmetic reasons. To overcome this issue, this study sought to compare 2 free gingival graft techniques that use oral screws to attach grafts. Free gingival graft was performed on teeth 44 to 46 using the traditional technique, while on the opposite side, on teeth 34 to 36, partly epithelialized free gingival grafts were performed. The partly epithelialized free gingival grafts were found to provide better cosmetic results relative to the completely epithelialized free gingival graft, and the use of stabilizing screws was found to be simple and effective.
