Summary

In this comparative trial, 50 patients with shallow vestibules and Type 1/2 recessions will be treated with either a vertically coronally advanced flap + connective tissue graft or a free gingival graft. At baseline, 3rd-month, 6th-month, and 12th-month visits, the following parameters will be evaluated: buccal vestibular depth, keratinized tissue height, gingival thickness, recession depth, recession width, probing depth, and clinical attachment level. Keratinized tissue change, gingival thickness change, root coverage, clinical attachment gain, and complete root coverage will be calculated. The wound healing index, tissue appearance, patient expectations, aesthetics, and dentin hypersensitivity will be assessed at baseline and at the 6th week.

Conditions

  • Shallow Vestibular Depth
  • Gingival Recession

Interventions

PROCEDURE

Vertically coronally advanced flap combined with connective tissue graft.

The exposed root surfaces are planed with Gracey 1-2 curettes. An intrasulcular incision is made with a blade on the buccal aspects of the involved teeth. The incision is extended horizontally to the adjacent papilla. Then, slightly divergent vertical releasing incisions are carried 2 mm beyond the mucogingival junction. A full-thickness flap is raised with a periosteal elevator towards the mucogingival junction. After that, a partial-thickness dissection is carried out in the apical direction to release muscle tension and provide coronal advancement of the flap. The adjacent papillae are de-epithelialized. The connective tissue graft (CTG) is harvested from the lateral palate using the de-epithelialized gingival graft technique. After harvesting, the connective tissue graft is sutured to the recipient bed. Finally, the flap is positioned 2 mm over the cementoenamel junction and sutured with 6-0 polypropylene sutures. No periodontal dressing is applied.

PROCEDURE

Free gingival graft

A partial-thickness flap is elevated (using a blade #15c) with horizontal incisions at the cemento-enamel junction (CEJ) level of the adjacent teeth. Then, two vertical incisions extending to the apical are made from the two ends of the horizontal incision. The epithelium in the framed region is removed with a scalpel, and the underlying connective tissue is exposed. To achieve the best vascularization of the free gingival graft from the recipient site, bed preparation is completed with a split-thickness horizontal incision that joins the vertical incisions in the apical region. The free gingival graft is stabilized using interrupted sutures and a sling suture.
