The Chao Pinhole® Surgical Technique (PST) is a gum rejuvenation technique that treats receding gums. The goal is to achieve full or partial root coverage and to strengthen thin, delicate gums.
This revolutionary surgical technique was developed by Dr. John Chao, who wanted a way to provide soft tissue grafting in a more minimally invasive way with less post-operative discomfort. His technique is now internationally acclaimed as dentists and periodontists around the world travel to learn this revolutionary technique. Learning under the mentorship of Dr. Chao himself, Dr. Pranata is excited to offer this treatment to her patients in the Vancouver area as a Pinhole® Academy Certified Dentist.
What is Gum Recession?
Gum recession is the loss of that pink gingival tissue that is the turtleneck collar around every tooth. With less gum tissue surrounding the neck of the tooth, the root becomes exposed and is prone to sensitivity to hot and cold. The exposed root is also at risk of developing cavities. Its natural roughness is a magnet for plaque, and its soft nature allows decay or acid erosion to make quick work on it. Maintenance and hygiene can also be challenging for teeth that suffer from gum recession increasing its risk for further recession, bone loss, and tooth loss.

How is the Chao Pinhole® Surgical Technique different from conventional soft tissue grafting?
PST® is unique in that unlike conventional soft tissue grafting, it does not require harvesting of tissue from the roof of the mouth (palate). Conventional grafting typically involves incisions and reflecting of the gum tissue using a scalpel, whereas PST® utilizes thin instruments specially developed by Dr. Chao, that are inserted into several small pinholes in the gums. These thin instruments are then used to loosen the gum from the inside so that collagen membrane may be placed underneath. In most cases, the pinholes heal in 24 hours.
Why Do Gums Recede?
There are many factors that contribute to gum recession. Here are some:
- Periodontal disease
- Aggressive tooth brushing
- Tongue ring or lip piercing
- Grinding or clenching habit
- Misaligned teeth
- Destructive bite
Am I a Good Candidate to receive PST®?
Just because you have some gum recession does not necessarily mean you are a good candidate to receive PST®. The Chao Pinhole® Surgical Technique has helped many people, but In some cases conventional soft tissue grafting may still be your best option. The best candidates for PST® have minimal to no bone loss and are committed to following a strict post-operative protocol. Inflammation and destructive forces must also have been dealt with or are eliminated in order to achieve the best results. Dr. Pranata will provide a thorough examination involving photos and x-rays to determine whether PST® is right for you. Book your appointment now to learn more!
