The application of concentrated growth factors membrane in oral mucosa tissue defect

Abstract

Objective To evaluate the clinical effects of CGF membrane for repairing the oral mucosa defects. Methods 39 patients were selected with oral mucosa defects after surgical resections. 19 defects were covered by autologous CGF membranes as the experimental group. 20 defects were not covered by membrane as the control group. Regular follow-up were performed at one week, two weeks, three weeks, one month, two months, three months after the operations. And wound healings were compared in the groups. Results CGF membranes of the 19 patients in the experimental group survived completely. And no infection occurred. The wound healing rate of the experimental group was higher than that of the control group at two weeks, three weeks and one month after the operations. And the difference was statistically significant(P<0.05). The VAS score of the experimental group was lower than that of the control group at one week, two weeks, three weeks and one month(P<0.05). The mean score of VSS score in the experimental group was lower than that in the control group (P<0.05). Conclusions Repair of the oral mucosa defects with CGF membrane can shorten the period of wound healing, relieve the postoperative discomfort and reduce the scar. It was a safe and effective method worthy to be popularized. Key words: Oral mucosa tissue; Concentrate growth factors Membrane; Defect; Repair
