Chao Pinhole® Surgical Technique



The Chao Pinhole® Surgical Technique (PST) is a comfortable, minimally-invasive, scalpel and suture-free technique for treating gum recession. Up to 84% of adults suffer from gum recession which can result in long and ugly teeth, sensitive roots and ultimately tooth loss. Traditional methods of treatment involve removing tissue from the palate and using sutures to secure it over root surfaces. This type of gingival (or “gum”) graft may result in varying degrees of postoperative pain, bleeding and/or swelling. If you have recession but are putting off treating it because you do not want to deal with postoperative discomfort or take time off of work, this treatment may be for you.
