What is Pinhole Surgical Technique™ in Sault Ste. Marie ON?

Gum recession breakthrough treatment also known as Pinhole Gum Rejuvenation and Lunchtime Gum Lift is a procedure in which Dr. Lawrence Chong, the certified Pinhole provider at Phi Dental Care, Sault Ste. Marie ON, 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, graft-free, suture-free, scalpel 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 choose Pinhole ®Surgical Technique (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.
