Beschreibung
Inclusion Criteria:
- patients attending the Clinic for Graduate Periodontics at The University of Texas health Science Center at Houston School of Dentistry who are in need of a Free Gingival Graft procedure to augment keratinized gingiva, augment ridge, or cover recession defects.
- systemically healthy or with controlled common systemic conditions, such as hypertension, that will not affect wound healing.
Exclusion Criteria:
- size of the FGG that the patient needs bigger than the size of FGGs that have to be harvested in this study (two 8mm (width) x 10mm (length) x ≈1.5mm (thickness) FGG).
- current heavy smokers(>10 cigarettes/day) (patients who stop smoking more than one year are eligible)
- have diabetes or other systemic diseases that may comprise healing
- take antibiotics and/or analgesics within one week before the procedure and have loss of sensation on the palate
