Revolutionary Patent for Gum Repair – Alhambra Dentist

Alhambra dentist, Dr. John Chao, was honored on June 11, 2012, at his office, by the Alhambra Mayor Barbara Messina for inventing a method of repairing receded gums, for which he was awarded two patents and a trademark from the U.S. Patent and Trademark Office, with the assistance of patent specialist, Attorney Kumar Maheshwari from the law firm of Foley and Lardner, LLP. An article describing and authenticating this method, called the “Pinhole Surgical Technique”®, has been accepted for publication by the International Journal of Periodontics and Restorative Dentistry.
