Pinhole Academy

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

🚨 Gingival Recession on Molars 🚨

Molars may not always be the first teeth we think of when it comes to gingival recession, but posterior recession can lead to root exposure, sensitivity, and even decay. Traditional grafting in these areas can be difficult due to limited attached gingiva and anatomical challenges.

With the Pinhole® Surgical Technique (PST), you can treat multiple areas in the same appointment—including molars—without scalpels or sutures. 🦷✨

✅ Minimally invasive
✅ Minimal downtime
✅ Treats multiple teeth in one session
