Intraoral-mucosal-xenogenous fascial grafting

Fascia obtained from the abdominal wall of a rat was transplanted into mucosal defects created in six dogs. In all of the dogs, the fascia was found to adhere firmly to the underlying tissue and surrounding epithelium. Biopsy specimens were taken at weekly intervals for 4 weeks. The defects healed without any apparent contracture and were covered by new epithelium. It appears that xenogenous fascia is a potentially useful graft material for intraoral soft tissues.
