About the Chao Pinhole Surgical Technique (PST®™)
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.

The unique features of the Chao Pinhole Surgical Technique®™ have aroused keen interest on the part of the media. So far news programs at 33 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, 2013.

Dr. Chao was granted a patent on the PST®™ method and another on the PST®™ instruments by the U.S. Patent and Trademark Office. For more information, please also see “The Pinhole Surgical Technique®™, A Novel Approach to Root Coverage,” as published in October, 2012 issue of The International Journal of Periodontics and Restorative Dentistry, a high-impact, peer-review journal. (Int J Periodontics Restorative Dent 2012;32:521-531.)

Through a small pinhole made by a needle, the doctor will use 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.

Dr. Futenma and his team strive to stay up to date on the latest technologies. If you would like more information on the Chao Pinhole Surgical Technique®™, please contact us.
