Gingival recessions are often successfully treated by coronally advanced flap technique (CAF) associated with subepithelial connective tissue grafts (SCTG). Currently the xenogeneic collagen matrix (CM) has been used as a substitute for SCTG associated with CAF technique for root coverage. CAF technique was not developed for use with CM and has shown limited results when applied to the CM. The aim of this study was to compare and show the benefits of the extended flap technique (EFT) compared to CAF technique using CM for root coverage.

| root coverage comparing two techniques | Device | The aim of this study was to compare and show the benefits of the extended flap technique (new technique) compared to coronal advanced technique (gold standard technique) both techniques using the porcine collagen matrix for root coverage. |
| Measure | Description | Time Frame |
|---|---|---|
| Comparing changes for Root coverage measure (in millimeter) from baseline at 3, 6 and 12 months | At the mid-buccal point of the involved tooth, the gingival recession height was measure by the same operator, who was previously calibrated (intra-examiner calibration) using a digital paquimeter. | Change from Baseline at 3, 6 and 12 months |
