About

The aim of this study is to investigate the effects of conventional suture (CS) and modified sling suture (MSS) techniques, applied in free gingival graft (FGG) surgery using gingival unit graft (GUG) and conventional graft (CG) techniques, on clinical parameters and graft dimensions.

Full description

Background: The aim of this study is to investigate the effects of conventional suture (CS) and modified sling suture (MSS) techniques, applied in free gingival graft (FGG) surgery using gingival unit graft (GUG) and conventional graft (CG) techniques, on clinical parameters and graft dimensions.

METHODS: 52 individuals having Cairo Type 2 (RT2) and Type 3 (RT3) gingival recessions in mandibular anterior region were divided into four groups as a) GUG+MSS (n=13), b) GUG+CS (n=13), c) CG+MSS (n=13) and d) CG+CS (n=13). Keratinized gingival width (KGW), keratinized tissue thickness (KGT), relative gingival recession height (rGRH), and relative vestibule depth (rVD) measurements were recorded using a digital caliper and periodontal probe UNC 15. Dimensional changes (Δ) of the graft surface area (GSA) was determined by ImageJ software. All measurements were done at baseline and repeated 1st and 3rd months.

Enrollment: 60 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers

60 participants in 4 patient groups

1. GUG+MSS

Experimental group

Description:

The GUG was obtained from the maxillary premolar area. The dissected graft was fixed to the recipient site using a modified sling suture technique.

Treatment:

Procedure: gingival unit graft+modified sling suture technique

2. GUG+CS

Experimental group

Description:

The GUG was obtained from the maxillary premolar area, as detailed experimental GUG+MSS group. The dissected graft was fixed to the recipient site using conventional suture technique.

Treatment:

Procedure: Gingival unit graft and conventional suture technique

3. CG+MSS

Experimental group

Description:

Conventional graft dimensions were determined with aluminum foil and the foil was placed in the palatial region at the level of the maxillary premolars, at least 2 mm away from the free gingival margin of the adjacent teeth. The dissected graft was fixed to the recipient site with 5/0 polypropylene suture using a modified sling suture technique, as detailed experimental GUG+MSS group.

Treatment:

Procedure: Conventional graft and modified sling suture technique

4. CG+CS

Experimental group

Description:

The dissected conventional graft, as detailed experimental CS+MSS group, fixed recipient bed with conventional suture technique, as detailed experimental GUG+CS group.

Treatment:

Procedure: Conventional graft and conventional suture technique
