Titanium fixation tacs versus sutures for securing free gingival grafts around dental implants

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

Not applicable Interventional Cairo University · NCT07019428

This test will see if using titanium fixation tacs to secure free gingival grafts in adults with inadequate keratinized gum around dental implants leads to more keratinized tissue gain than using sutures.

What this trial studies

This randomized, controlled, parallel-group trial enrolls eligible adults to receive a free gingival graft from the palate that is secured either with titanium fixation tacs or with conventional sutures. The primary outcome is the width of keratinized gingiva measured after healing using standardized clinical measurements at scheduled follow-up visits. Investigators hypothesize that tacs will reduce operative time and improve intimate graft stabilization, which may reduce healing contraction and improve tissue adherence. The single-center study is conducted at the Faculty of Dentistry, Cairo University with strict inclusion and exclusion criteria to select healthy non-smoking participants.

Who should consider this trial

Good fit: Healthy non-smoking adults aged 18–40 with less than 2 mm of keratinized gingiva around dental implants, good plaque control, no active periodontal disease, and no contraindicating medical conditions are ideal candidates.

Not a fit: Patients who smoke, have systemic disease, take blood thinners or drugs that cause gingival enlargement, are pregnant or lactating, undergoing orthodontic treatment, or have active periodontal disease are unlikely to qualify or benefit.

Why it matters

Potential benefit: If successful, using titanium tacs could shorten surgery time, improve graft stability, and result in greater keratinized tissue gain with potentially less postoperative discomfort.

How similar studies have performed: Fixation tacks and similar anchoring devices have been reported in mucogingival surgery with favorable case series, but randomized head-to-head evidence against sutures is limited.
