The Pinhole Surgical Technique (PST) is a newer, minimally-invasive technique that avoids the use of scalpels and sutures (stitches) by utilizing tiny access points in the gums to loosen the gum tissue. Once the gums are pulled over the recessed roots, collagen is placed into the site to thicken the gum tissue. The benefit of the PST is not having to use sutures that may become bothersome later in the healing, and there is much less discomfort, if any at all, than using palatal grafts.
Soft tissue grafting is often necessary to combat gum recession. Periodontal disease, trauma, aging, over brushing, and poor tooth positioning are the leading causes of gum recession which can lead to tooth-root exposure in severe cases.
When the roots of the teeth become exposed, eating hot and cold foods can be uncomfortable, decay is more prevalent and the aesthetic appearance of the smile is altered. The main goal of soft tissue grafting is to either cover the exposed root or to thicken the existing gum tissue in order to halt further tissue loss.
