Soft Tissue Volume Gain and Stability Comparing Palate and Tuberosity

"Recipient site: Intrasulcular incision at the buccal side of the implant extending in one adjacent tooth for each side and a partial-thickness mucosal flap raised. The connective tissue was secured with suture. Allocation to either treatment was performed according to a randomization table.~Donor site A double-bladed scalpel handle 1,5mm was used in both areas to obtain the same thickness.~Palate (CG) The double incision was made approximately 2 to 3 mm apical to the gingival margins of premolars. The donor tissue was removed and cross-mattress sutures were used to approximate the wound on the palate.~In both groups the epithelial collar removed. Graft required dimensions for both groups:10mm height, 12mm length and 1,5mm thick."

The connective tissue was secured with suture. Allocation to either treatment was performed according to a randomization table.~Donor site A double-bladed scalpel handle 1,5mm was used in both areas to obtain the same thickness.~Tuberosity (TG) The double incision was made from the distal of the terminal tooth. A second incision was made perpendicular to the linear incision at a distal point, which joined the two linear incisions. The graft was removed and a crossed horizontal suspension suture was used.~Epithelial collar removed. Graft required dimensions for both groups:10mm height, 12mm length and 1,5mm thick."

Intraoral optical scan was performed at both groups at baseline, 3 months, 4 months and 12 months to be able to compare volumetric changes.
