This new, minimally invasive technique is used to treat gum recession. Gum recession refers to the loss of gum tissue along the gum line. Gum recession can occur as a result of periodontal disease (gingivitis, periodontitis, or advanced periodontitis). This technique works best with existing good gum tissue. There are no skin grafts needed with this technique. It simply involves the adjustment of the existing tissue.

How it Works

During the Chao Pinhole Surgical Technique, an instrument is used to make a small hole in the patient’s existing gum tissue. Through this pinhole, special instruments are used to gently loosen the gum tissue. These tools help expand and slide the gum line to cover the exposed root structure.
