Summary

This study is to compare the two techniques to achieve change in the tissue quality at areas of lack of Keratinized Tissue (KT) using soft tissue grafting with autogenous graft material (Free Gingival Graft)(FGG) vs Strip gingival graft with acellular dermal matrix (ADM) (SGG+ADM).

Conditions

  • Gingival Recession
  • Lack of Keratinized Attached Peri-implant Mucosa
  • Thin Gingiva

Interventions

PROCEDURE

Strip Free gingival graft (SGG) + Acellular Dermal Matrix graft (ADM)

A horizontal incision is then placed at the middle of residual KT. Two vertical releasing incisions are followed to allow for apical displacement of the flap. The flap will be then elevated with a split-thickness flap beyond the mucogingival junction where it is sutured at this apical position using a mattress (5-0, monocryl) suture. The recipient site should ideally retain intact periosteum that is firmly attached to bone with no loose fibers, no irregularities and no perforations.

PROCEDURE

Free Gingival graft

Two vertical incisions are made, and a partial thickness flap are designed to provide a firm and immobile periosteal bed. The raised partial thickness flap will be excised. Muscle and unattached connective tissue fibers are thoroughly scraped with a scalpel to prevent graft mobility. Autogenous FGG was harvested with #15C scalpel blade from hard palate at the same side randomly selected to receive the FGG. Donor area was sutured with 5-0 gut sutures. FGG, is placed and stabilized with simple interrupted 5-0 vicryl sutures at recipient site coronal border and horizontal or periosteal anchorage sutures over the graft.
