The Chao Pinhole® Surgical Techniqueis a minimally invasive option for treating gum recession. Unlike traditional grafting techniques, PST™ is scalpel and suture free. Traditional gum recession treatments involve the use of donor tissue or soft tissue grafts in order to rebuild the gumline. This soft tissue would be sutured in place and would join with existing gum tissue as it healed. While this traditional grafting treatment is effective, comparable results with better patient experience can be achieved through the Chao Pinhole® Surgical Technique.
