How PST (Pinhole Surgical Technique™) is done:
Dr. Chao says that the affected teeth are cleaned and prepared, and the gum tissue is numbed with a local anesthetic. A small entry point is made in the gum above the tooth or teeth to be treated.
A specialized dental instrument designed and patented by Dr. Chao is inserted into the entry point and moved to free the gum tissue, then the gums are gently guided down to their proper position. Next, the dentist uses a small angled instrument to pass several collagen strips through the entry point and place them under the gums. “The collagen helps to keep the gum tissue in place and stimulates the body to generate more collagen. PST takes about a half an hour to an hour and as many as ten teeth can be treated at the same time. The small entry point quickly heals and is virtually undetectable the next day,” says Dr. Chao.
Until the invention of the Pinhole Surgical Technique™, gum grafting surgery was the standard treatment for receding gums,” says Dr. Chao. “However, gum grafting requires a scalpel to cut and remove a section of gum from the roof of the mouth which must be sutured in place over the area of recession. Because of the cutting and stitches required most dentists generally will only treat one or two teeth at a time, then the patient will need to heal before having more teeth done,” he says.
“The Pinhole Surgical Technique™ can address several teeth through just one tiny entry point, and unlike gum grafting, multiple teeth can be treated in one session,” says Dr. Chao
