The Pinhole Academy is the training center for The Pinhole Surgical Technique. Invented by Dr. Chao

The Pinhole Surgical Technique (PST®), invented and patented by John Chao, D.D.S., is a scalpel-free, suture-free procedure for correcting gum recession. Through a small pinhole made by a needle, Dr. Chao uses specially designed instruments to gently loosen the gum tissue and glide it over the receded part of the tooth. Since there is no cutting or stitching, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.
