The Chao Pinhole Surgical Technique (PST) is a minimally invasive treatment for restoring receding gums. Unlike painful and invasive gum grafting surgeries, the Pinhole procedure is minimally invasive. Invented and patented by John Chao, D.D.S., it is a scalpel-free, suture-free procedure for treating gum recession.
This procedure is performed by making a small hole with a needle in the gum tissue. Using specially designed instruments, the gum tissue is loosened and guided over the receded part of the tooth. Since there is no incision or suturing, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.
Pinhole not only improves the appearance of your smile, but it also protects your teeth from further deterioration. The results can last for years, providing long-term benefits for patients. Recovery times are also minimal compared to gum grafting, and patients will typically return to normal activities within 24-48 hours.
