Connective Tissue Grafts
This is the most common type of graft. In this procedure, the team will remove a small bit of skin from under the roof of your mouth and attach it to the problem area with stitches. A small flap is cut in the palate to access the tissue underneath; it’s stitched close at the end of the procedure. This kind of tissue is called subepithelial connective tissue and it attaches readily to the gum tissue at the problem site, correcting the recession.
Free Gingival Grafts
A free gingival graft uses tissue directly from the roof of the mouth instead of under it. This is the only difference between the two procedures. It is often used when thicker pieces of tissues are needed for the graft.
A pedicle graft uses gum tissue from near the tooth. A cut is made in the tissue and the resulting flap is pulled down over the exposed tooth and stitched into place. It can only be done if the patient has a lot of gum tissue near the problem tooth.
