Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (CM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The CM has the advantage of no need of a second surgical area and availability overcoming the limitations of donor site in autograft.
The aim of this study is to investigate the use of Mucoderm® in root coverage procedures combined with extended coronally positioned flap (ECAF), test group (TG), in comparison to the connective tissue graft associated with the ECAF, control group (CG).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Test Group | Active Comparator | Active comparator: gingival recession the aim of this study is to compare if the collagen matrix graft is as efficient as a substitute for the connective graft used in root coverage of gingival recessions |
|
| Control Group | Placebo Comparator | the aim of this study is to compare if the collagen matrix graft is as efficient as a substitute for the connective graft used in root coverage of gingival recessions. The control group was treated with the same technique as the collagen matrix graft. |

| Root coverage with collagen matrix graft | Procedure | at one side, the root coverage have been done with a extended flap technique and collagen matrix graft. At the other side, the same technique was performed with connective graft. |
| Measure | Description | Time Frame |
|---|---|---|
| Root coverage after 6 months | Root coverage is measured by the difference between the gingival recession height at 6 months and baseline | 6 months |
