|This procedure is designed to replace or enhance the amount of gum
supporting a tooth. Coverage of root surfaces exposed due to previous recession is also
possible to achieve. These procedures are performed when there is inadequate gum remaining
to help support a tooth or excessive recession has occurred exposing the root of the
There are basically TWO types of Gum Grafts (Free
- 1. Submarginal Graft: This type of graft is the most
predictable and is not meant to cover the root surface that has been exposed. It is
meant to be placed at the current gum margin and to protect the underlying bone with a
layer of tougher keratinized gum tissue that has been transplanted from another site
(usually the roof of the mouth).
- 2. Root Coverage: This type of gum graft is designed to
cover the root surface. It is not as predictable as the submarginal graft and is
meant to be placed in areas that are highly visible such as the upper front teeth.
This type of graft can be performed in several ways and may sometimes take two surgical
steps. The most common method is a Connective Tissue Graft. The gum is taken from
the palatal submucosal tissue and then placed directly over the root; there tends to be
more discomfort post-surgically. Recently, there has been developed a synthetic
tissue without the need for a donor area (palate); this makes the procedure much more
pleasant, but again is not fully predictable.
