Periodontal Grafting Proceedures
Why is grafting needed?
- To increase the amount of attached gingiva (thicker non-mobile gum-tissue which is the first line of defense against recession, root exposure and tooth loss)
- To cover some or all of existing recession
- To prepare a site prior to orthodontic movement of teeth (in particular proclination).
Types of grafts:
- Free Gingival Graft:
- Used for augmentation of attached gingiva (not usually intended for root coverage)
- Most common type of graft
- Relatively thin palatal gingiva (skin from the roof of the mouth) is harvested and sutured at the deficient site to increase attached gingiva.
- Connective Tissue Graft:
- Employed to increase the amount of attached gingiva and to provide some root coverage.
- Complete root coverage may not be possible in all cases.
- A more sophisticated procedure involving the use of palatal connective tissue (thicker tissue from the inside of palate) to cover the recession area.
