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.

🎉 1-Week Follow-Up! 🎉
Just wanted to share an early update on a recent upper arch case using the Pinhole Surgical Technique®.

We saw the patient back one week post-op, and everything is looking great so far. Still early, but very pleased with how things are progressing. Excited to continue following this case and see the final results take shape over the coming months!
