What is PST™?
The Pinhole Surgical Technique PST™ is a procedure in which Dr. Clark uses specialized instruments to make a small hole in your gum and add collagen material which stabilizes the area of gum recession. This new method is simple, suture-free and minimally invasive.
PST™ was developed and patented by John Chao, D.D.S. It has been featured in the International Journal of Periodontics, one of the most prestigious dentistry journals in the world.
