Pinhole Surgical Technique™


You’re not alone if you find yourself asking, “I have big teeth and very little gums. I don’t smile very often anymore because I am so self conscious of my teeth. Is there a way to improve my smile?”

The Chao Pinhole Surgical Technique allows for the immediate treatment of more teeth with fewer visits, with less discomfort than traditional soft tissue techniques. Dr. Piehl is one of a select few dentists worldwide who is certified in this technique.

This method does not require sutures or a second surgical site. This greatly minimizes patient discomfort while still achieving results similar to traditional methods for treatment. 

A recent Yelp review is a common response from patients: 

 I must say quite frankly, that the procedure was far less painful than I imagined and the results – well, quite amazing, incredible even.I had the pinhole surgical technique procedure by Dr. Piehl. I was very reluctant at first, not to mention somewhat frightened, to undergo the procedure given my low tolerance for pain and discomfort. I was very pleased with the final results, and am a big fan of Dr. Piehl and his wonderfully helpful and friendly staff. I would heartily recommend Dr. Piehl for the pinhole surgical technique. He is amazing. Thanks Dr. Piehl.”

What is PST™?

The Pinhole Surgical Technique PST™ is a procedure in which Dr. Raschkovsky 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.

Why Do We Get Gum Recession?

While gum recession is usually viewed as one of the symptoms of gum disease, it can also be caused by insufficient tooth brushing, overly aggressive tooth brushing, or from certain medications that can affect gum health. Gum recession can even be caused by orthodontic treatments and appliances like braces or retainers.

Why choose PST™?

Unlike gum grafting, The Pinhole Surgery Technique™ is minimally invasive and does not cut gum tissue, making it a much less painful option. Gum recession was traditionally treated using a connective tissue graft, which “harvests” gum tissue from the roof of the mouth and then sutures it to the affected area. Connective tissue grafts have a recovery period of up to three weeks and patients often experience side effects including: gum pain, swelling and bleeding. Palatal tissue grafts (tissue taken from the roof of your mouth) also have a different esthetic appearance than normal gum tissue, as the color and texture of roof tissue does not match that of your gums. Other methods, such as using donor tissues, may require intricate suturing, leading to possible complications and infection.
