Dr. Chao’s involvement with the Post-Graduate Periodontics Program at the University of Buffalo, SUNY, speaks to the depth of his knowledge and experience in the scientific investigation of gum disease. As a Research Assistant Professor at this university, Dr. Chao is involved in a major study comparing the Pinhole Surgical Technique, his invention, to the standard treatment for gum recession called the Connective Tissue Graft. Dr. Chao will be one of the authors of this new study.
The Chao Pinhole® Surgical Technique (PST), invented and patented by John Chao, DDS, MAGD, is a scalpel-free, suture-free procedure for correcting gum recession. Through a small hole made by a needle, Dr. Chao uses specially designed instruments to gently loosen the gum tissue and glide it over the receded part of the tooth. Since there is no cutting or stitching, patients can expect minimal post-operative symptoms (pain, swelling and bleeding). Most patients also are pleasantly surprised by the instant cosmetic improvement.
