Effectiveness of Full-thickness Palatal Graft Technique (FTPGT) in Obtaining Complete Root Coverage

"The recipient bed will be prepared according to Langer\&Langer modified technique. Intrasulcular incision will be performed from at least one tooth mesial and one tooth distal to the tooth with gingival recession, without vertical incisions.A split-thickness flap will be raised.The harvest of palatal graft will be done using FTPG technique. An incision, parallel to the gingival margin, deep to the bone, will be made. At the center of this incision, a U shaped one about 1-2mm deep will made, with the convex side towards the palatine vault.The width of the U incision will be equal to the width of the GR and the length will be 1mm greater.A split-thickness dissection of the area surrounding the U shaped incision will be done.The graft will be removed by detaching it from the bony surface.The graft will be made up of an apico-lateral portion of connective tissue and periosteum, and of a full-thickness central part.The palatal graft will be adapted to the recipient site and sutured."

According to De Sanctis \& Zucchelli, a tension-free trapezoidal flap will be elevated by the split-full-split technique and the anatomic papillae will be de-epithelialized. A 1-mm thick SCTG will be harvested from the palate as epithelialized graft. The height of the graft was equal to the distance between the buccal bone crest and the CEJ. After epithelium removal, the graft was positioned and sutured 1mm apical to the cement-enamel junction with 5-0 resorbable sutures . The SCTG will then be covered by the tension-free coronally positioned flap, sutured about 2mm over the CEJ by 5-0 silk sutures.
