Chao Pinhole® Surgical Technique Animation
The Chao Pinhole® Surgical Technique (PST™), invented and patented by John Chao, D.D.S., is an incision-free, suture-free procedure for treating 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 incision or suturing, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.
The unique features of the Chao Pinhole® Surgical Technique have aroused keen interest on the part of the media. So far news programs at 240 TV stations have featured this incision-free technique of treating a problem that is found in half of the U.S. population (JADA, 2003). Dr. Chao made a guest appearance on the Dr. Steve Show which was broadcasted nation-wide during the week of September 15-22. You may have already heard questions and comments from your colleagues and patients about this "breakthrough" method of correcting ginigival recession.
Dr. Chao was granted a patent on the PST method and another on the PST instruments by the U.S. Patent and Trademark Office.
