Clinical Evaluation of a Modified Technique for Free Gingival Graft Stabilization Using Titanium Fixation Tacs Around Implants Versus Conventional Suturing Technique

Free gingival graft obtained from the palate, usually replaces missing or lost keratinized tissue. Although it represents the gold standard, its success relies on providing intimate and atraumatic stabilization, as maintaining the plasmatic circulation is crucial for graft healing and perfusion, considering that judging the success of free gingival graftis based on the extent of the postoperative healing contraction and the quality of graft adherence to the underlying periosteum.

Suturing can be time consuming and sometimes fail to achieve a positive result. Also it was reported that for every one-minute increase of the gingival augmentation procedure time, there is a 4% likely increase for pain and a 3% for swelling.

However, by using fixation tacs the surgical time can be significantly reduced and the procedure can be less technique sensitive.
