The Chao Pinhole® Surgical Technique is an innovative method of correcting gum recession and creating a healthier, more pleasing smile. The PST™ is not just an improved method of grafting, however. This procedure is completely different from the conventional grafting method used to replace gum loss with tissue from the roof of the mouth. Here is a look at the major differences between the PST™ and grafting surgery.

The Grafting Procedure

Grafting replaces missing gums with tissue taken from the roof of the mouth. This requires use of a scalpel and sutures:

  • A scalpel is used to cut and remove a piece of tissue from the palate
  • Sutures are used to close the incision in the palate
  • The receding gums are cut with a scalpel and lifted over the area of the recession
  • The tissue from the roof of the mouth is placed over the teeth where the gums have receded
  • The cut and lifted section of the receding gums is then placed back down over the tissue graft
  • Sutures are added to the area around the graft

The gums and sutures then hold the graft into place.

The Chao Pinhole® Surgical Technique

The PST™ procedure is radically different than the grafting method. One pinhole incision is made in the gums with a patented tool so that the gums can be moved:

  • A special instrument is angled to loosen the gums from inside the pinhole
  • The gums are then moved down into a healthy position
  • Tiny collagen strips are placed behind the gums through the pinhole to help stabilize the gums

PST™ improves the appearance of the gums immediately. There are no incisions to heal or visible sutures since no cutting or stitching is necessary. The pinhole can heal as quickly as overnight.
