What is so revolutionary about the Pinholesurgical Technique for rejuvenating gingiva? What is better about Pinholesurgical Technique than a conventional gingiva transplant?  In order to understand the advantages of PST over conventional gingiva restoration, it is important to know the method involved in both techniques. In both instances, all of the preliminary treatments must first be concluded. Any inflammatory processes must be completely healed beforehand. The patient must be informed in consultations of all pertinent strategies for oral hygiene such as correct tooth brushing. Thorough preliminary examinations and consultation are necessary for Pinholesurgical Technique and gingival transplantation.


Gingival transplantation

There are many ways to replace lost gingiva surgically using the body’s own gum tissue. Most frequently, “free connective tissue transplantation” is used. In this procedure, the surgeon removes a small piece of tissue from the gums, cheek or between the teeth. Local anaesthesia is used, of course, so that the patient does not feel any pain. The location where the gingiva has receded (“receiver bed”) is opened up as described in the following video <LINK Video Dr. Chao>. The “receiver bed” is then cleaned gently but thoroughly. Then the connective tissue is applied and secured with sutures or, in rare instances, tissue adhesive. Needless to say, the site where the tissue was removed must also be treated. This is either done using sutures, or a bandage is applied. This bandage is made of plastic. Several follow-ups are needed after gingiva transplantation to ensure that all of the wounds heal well and without complications. Generally, the cost of gingiva transplantations is not borne by health insurance, since there is no direct danger to the tooth in most cases.


Gum lifting by Pinholesurgical Technique

Gum lifting by Pinholesurgical Technique based on the method by Dr. John Chao has been used since 2006. The gingiva of tens of thousands of PST patients across the world has been successfully restored through Pinholesurgical Technique. The method used in gum lifting is simple: under local anesthesia, a small access hole (pinhole) is created at the locations affected by gum loss. With a special instrument, the dentist loosens the existing gingiva and moves it to a new position.  The gingiva is then secured using collagen membranes. In principle, the treatment generally does not take more than 60 minutes. The access hole usually closes up by the next day. In order to perform Pinholesurgical Technique, dentists need to be trained in person by Dr. John Chao. Furthermore, specially developed and patented instruments are needed. The cost of gum lifting is also not borne by health insurance companies for the same reason as gingiva transplantation.


Differences between methods

It should first be noted that the prospects of success are equally high for both methods. Both Pinholesurgical Technique and gingiva transplantation are recognized in the dental profession and are tried and tested methods for restoring lost gingiva. The method involved with PST significantly differs from gingiva transplantation, though. The primary difference is that Pinholesurgical Technique is minimally invasive. PST involves a minimal amount of effort; the number of healing wounds is minimized. Furthermore, this obviously significantly reduces the gum lifting treatment than is the case with gingiva transplantation.


Advantages of Pinholesurgical Technique

Gingiva transplantation involves major surgery. When a large area needs to be treated, the question arises: Is there enough available tissue for transplantation? Furthermore, certain risks exist that are absent with gum lifting. The healing of incisions which are numerous with major treatments is an issue. Potential scars are also an issue. Gum lifting using Dr. John Chao’s method can also be repeated after a number of years if the gingiva recedes once again, for example due to incorrect toothbrushing. Frequently, gingiva transplantation cannot be carried out a second time. Further advantages of gum lifting are:

  • short treatment duration
  • short absences from work
  • less pain during the healing phase; only pinholes as opposed to incisions
  • excellent results and pleasing aesthetics
  • patented method, effectiveness documented by a long-term study
