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.

11 years later — and we’re grateful to be able to share moments like this.
Over the past few posts, we’ve been highlighting long-term Pinhole® Surgical Technique cases, and this one is especially meaningful because it reflects something we truly value: patients who have trusted Dr. Chao with their care for many years.
Long-term follow-up gives us the opportunity to see results in real time, over time — not just immediately after treatment, but years down the road.
We are grateful for the patients who continue to return, share their progress, and allow us to observe the long-term impact of Dr. Chao’s work.
This case shows a pre-operative view and an 11-year post-operative view following the Pinhole® Surgical Technique.
