WHAT IS PST™?
The Pinhole Surgical Technique PST™ is a procedure in which the doctor uses specialized instruments to make a small hole in your gum and add collagen material to stabilize 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.
Why Do We Get Gum Recession?
While gum recession is usually viewed as one of the symptoms of gum disease, it is most often unrelated to disease caused by insufficient tooth brushing, overly aggressive tooth brushing, or from bruxism. Gum recession can even be caused by orthodontic treatments.
Why choose PST™?
Unlike gum grafting, The Pinhole Surgery Technique™ is minimally invasive, making it a more comfortable option. Gum recession is traditionally treated using a connective tissue graft (CTG), which “harvests” gum tissue from the roof of the mouth and then sutures it to the affected area. Connective tissue grafts have a longer recovery period compared to PST. An alternative to CTG is the use of donor tissue, but requires intricate suturing.
