Gingival Recession, Localized | Procedure: Coronally Advanced Flap combined with a Connective Tissue Graft Procedure: Coronally Advanced Flap combined with a Meshed Connective Tissue Graft Device: Meshing of Connective Tissue Graft | Not Applicable |
Gingival recession defects (GRD) present as a partial exposure of the root surface resulting from gingival margin displacement apical to the cemento-enamel junction (CEJ). A variety of surgical methods have been reported to reestablish root coverage, including tunneling techniques and coronally and laterally advanced flaps. As thin gingival tissue is one of the predisposing factors for GRD, the adjuvant use of subepithelial connective tissue grafts (CTG) is often considered. CTG is thought to contribute to phenotype modification and stability of treatment outcomes and studies have indicated favorable esthetic results and high degrees of root coverage (documented range: 69% to 97%). The procedure does, however, require a suitable donor site. When multiple adjacent teeth exhibit GRD, the preferred surgical approach should offer the greatest root coverage while limiting drawback (i.e., patient morbidity, esthetic problems). Thus, one of the challenges related to root coverage is the scarcity of donor tissue. In cases when large CTGs are required, additional surgical procedures may even be necessary. As an alternative, modification of the harvested CTG into an expanded "mesh CTG" (mesh-CTG) has been proposed for the treatment of multiple adjacent GRDs (MAGRD). However, the effectiveness and predictability of mesh-CTG using the coronally advanced flap (CAF) has not yet been evaluated in direct comparison to conventional CTG.
We hypothesise that no statistically significant differences will be observed in terms of %root coverage and patient satisfaction at 12 months. Subjects in the test group (mesh-CTG) will report significantly lower morbidity at 1 and 2 weeks post-surgery when compared to controls.

Active Comparator: Connective Tissue Graft
A mucogingival surgery where a conventional connective tissue graft harvested from the palate is placed on a recipient site prepared for modified coronally advanced tunnel and sutured to cover multiple adjacent gingival recession defects.
|
Procedure: Coronally Advanced Flap combined with a Connective Tissue Graft
Multiple adjacent gingival recession defects will be covered by coronally advanced flap combined with a connective tissue graft harvested from the palate. |
Experimental: Meshed Connective Tissue Graft
A mucogingival surgery where a meshed connective tissue graft harvested from the palate is placed on a recipient site prepared for modified coronally advanced tunnel and sutured to cover multiple adjacent gingival recession defects.
|
Procedure: Coronally Advanced Flap combined with a Meshed Connective Tissue Graft
Multiple adjacent gingival recession defects will be covered by coronally advanced flap combined with a meshed connective tissue graft harvested from the palate. Device: Meshing of Connective Tissue Graft The harvested connective tissue graft is meshed with a scalpel blade before being unfolded and placed on the recipient site. |
