The experimental groups (A and B) will be treated through the association of subepithelial connective tissue graft (SCTG) and coronally advanced flap. Each individual will receive the types of treatment, randomly assigned to the right or left side. Group A will receive the submucosal predominant area for SCTG (removed from the anterior region of the lateral palate, more deeply) by the double-blade technique (Harris, 1997). This collection method allows a uniformity of the SCTG with standard thickness (1.5mm). Thus, the scalpel cable with double blades (1.5mm distance) will be used. The initial horizontal incision will be made on the palate, preserving 1-1.5 mm from the gingival margin of the teeth, until the complete deepening of the number 15C blades in the necessary extension previously defined for the receiving area. Internal vertical incisions will be performed for both sides of the horizontal incision and at the base of the graft to enable the SCTG removal. After the graft removal, the epithelial portion is extracted for subsequent stabilization of the graft to the recipient site.
