What is the Chao Pinhole® Surgical Technique(PST)?

Chao Pinhole® Surgical Technique was invented and patented by John Chao, DDS, MADG, is a scalpel-free, suture-free procedure for correcting gum recession. Through a small hole 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. Patients can expect minimal post-operative symptoms. Most patients also are pleasantly surprised by the instant cosmetic improvement.

 The unique features of the Pinhole Surgical Technique have aroused keen interest on the part of the media. So far news programs at 240 TV stations have featured this scalpel-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 nationally syndicated "The Doctors Show," "Dr. Steve Show," "ABC," "NBC," and over 240 other stations across the U.S. and Canada, reaching an estimated 10 million viewers. For this reason, you may have already heard questions and comments from your colleagues and patients about this "breakthrough" method of correcting gingival recession.

 Dr. Chao was granted patents and trademarks on the PST method and PST instruments by the U.S. Patent and Trademark Office.

Introducing A Breakthrough Treatment for Gum Recession

What is gum recession?

Gum recession refers to the loss of gum tissue along the gum line. This can occur as a result of periodontal disease (gingivitis, periodontitis, advanced periodontitis), the natural aging process, or abrasive habits when it comes to brushing the teeth.

Why should gum recession be taken seriously?

When gum recession occurs, the root structure of the tooth becomes exposed. This means that tooth decay and other problems can affect the teeth along the gum line and beneath it. Since healthy gums are essential for a healthy mouth, getting gum recession treated is important for lasting dental wellness. 

What is the Chao Pinhole® Surgical Technique (PST)?

The Chao Pinhole® Surgical Technique is a minimally invasive option for treating gum recession. Unlike traditional grafting techniques, PST is scalpel and suture free. All of the tools and techniques used to perform the Chao Pinhole® Surgical Technique were created by Dr. John Chao.

How does the Chao Pinhole® Surgical Technique (PST) differ from traditional gum grafting?

Traditional gum recession treatments involve the use of donor tissue or soft tissue grafts in order to rebuild the gum line. 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.

How is Chao Pinhole Surgical Technique (PST) performed?

During the Chao Pinhole Surgical Technique, a needle is used to make a small hole in the patient’s existing gum tissue. Through this pinhole, special instruments are used to gently loosen the gum tissue. These tools help expand and slide the gum line to cover the exposed root structure.

There are no grafts, no sutures, and no incisions needed with the Chao Pinhole Surgical Technique. It simply involves the adjustment of the existing tissue.

What are the benefits of Chao Pinhole® Surgical Technique (PST)?

The benefits of the Chao Pinhole® Surgical Technique are many:
