Pinhole Academy

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-opera

tive symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.

Not the Final Result—Just 3 Weeks Into Healing 🦷

This clinical comparison shows the treated area before PST™ and at the 3-week post-operative visit.

At this early stage, the gum tissue is still healing and maturing. Its position, color, and contour may continue to change over the coming weeks and months. Take a closer look at the gumline—what do you notice first? 👀

Dr. John Chao is the inventor of the Pinhole® Surgical Technique (PST™) and has trained over 4,000 dentists worldwide. PST™ is a scalpel-free, suture-free, minimally invasive approach for treating gum recession.

This is an early post-operative clinical observation, not the final healed result. For educational purposes. Individual results may vary.

A Challenging Starting Point—Six Weeks Into Healing 🦷

This clinical comparison documents a pronounced recession site before treatment and at the 6-week post-operative visit following PST™.

At this stage, the tissue is still healing and maturing. Its color, contour, and position may continue to change over the coming weeks and months, so this is not the final result.

PST™ is used to address gum recession; any decay or restorative concerns require separate evaluation and treatment.

21 Days Into the Healing Journey 🦷

This clinical comparison shows the gum-recession area before PST™ and at the 3-week post-operative visit.

At this stage, the tissue is still actively healing and maturing. Its color, contour, position, and overall appearance may continue to change over the coming weeks and months, so this early follow-up should not be considered the final result.

Follow along as we continue documenting the healing process. 👀

Where Healing Stands at Week 6 🦷

This clinical comparison shows the treated area before PST™ and at the 6-week post-operative visit.

At six weeks, the tissue is still healing and maturing. Its color, contour, and position may continue to change over the coming weeks and months, so this should not be considered the final result.
