Chao Pinhole Surgery vs. Gum Grafting to Treat Gum Disease

Chao pinhole surgery is a revolutionary way to treat gum disease. However, it is important to understand what your options are to treat gum disease. Gum grafting is also used as an effective tool in the fight against gum disease. There are specific benefits and drawbacks of each treatment and understanding the nature of each procedure can help you have an educated discussion with your dentist about what the best choice is for your specific case.

Understanding Gum Recession

Gum recession is when the gum line has receded down the tooth. This can change the visible look of your smile and expose the roots of your teeth to more bacteria and potential infection. The roots of your teeth are not covered with enamel like the natural surfaces of your teeth. The enamel acts as a protective barrier that doesn’t allow bacteria or sugars to manifest into cavities. When the roots of teeth are exposed, patients can experience an increase in the number of cavities and even tooth loss.

Properly treating gum recession is a critical component to your overall health. Restoring gums is typically accomplished through gum grafting or the Chao Pinhole technique. While these two procedures both aim to restore your gumline, they have some significant differences.

Gum Grafting

The gum grafting procedure can vary depending on the severity of gum recession, but the typical procedure utilizes donor tissue that is then sutured onto the gums. The body should recognize this donor tissue as your own, and over time the donor tissue and the patient’s natural gumline will heal together. This process helps to build up the gumline and protect your teeth while restoring your overall dental health.

Chao Pinhole Technique

This technique is considered a minimally invasive procedure to restore the gumline. It varies from traditional gum grafting procedure because it does not require any incisions or sutures. Instead, the Chao Pinhole technique uses a fine needle to make a pinhole in the gum tissue. Special instruments are then inserted through the pinhole and expand the gum tissue. With more available volume, the gums can be adjusted to cover more of the exposed tooth and raise the gumline.

The Benefits of Chao Pinhole

The Chao Pinhole technique is a great improvement for many patients and offers significant advantages over gum grafting. When donor tissue is taken from the patient, it is taken from the palate, creating an additional wound that requires healing and has the potential for infection.

If the tissue is taken from another source, there is an increased potential for infection or complications due to a rejection of the tissue. There are no incisions or sutures needed for the pinhole technique. This translates to reduced recovery time, and less discomfort for the patient throughout the healing process.

The Chao Pinhole technique also offers improved results. The gumline appears natural, with no suture or healing lines. The results are long-lasting and can be easily maintained through excellent oral hygiene.

This technique can also cover larger areas in a single visit. This means, that while skin grafting may require multiple visits in order to complete grafts for the entire mouth, the Chao Pinhole technique can treat your entire gumline in a single dental appointment. This reduces the time that you spend in the dentist’s chair, scheduling appointments, traveling, and reduces your overall healing time!
