Coronal positioning of tissue previously treated with freeze-dried dura mater grafts. Report of a case.

Root surfaces exposed to the oral environment may present a variety of problems to dental patients. Mucogingival surgical procedures represents one approach to the management of these concerns. Procedures currently in use often require two or three wounds, and sometimes two surgical sessions. Recent observations suggest that an allograft, freeze-dried dura mater, amy serve as a donor material in mucogingival surgery. This report describes the use of coronally positioned flap procedures to treat residual areal of recession 4 years after placement of freeze-dried dura mater allografts.
