The Pinhole Surgical Technique (PST®), invented and patented by John Chao, D.D.S., is a scalpel-free, suture-free procedure for correcting gum recession. This technique, used in my office since 2015 does provide similar clinical outcome as conventional grafting techniques, yet with minimal discomfort for the patient. This case is healing at only 6-weeks. No sensitivity, no pain... Patient was referred from Dr. Oscar Marin's general dental office in West Covina, CA.
