GUIDED TISSUE REGENERATION IN MUCOGINGIVAL SURGERY

THE USE OF EXPANDED POLYTETRAFLUOROETHYLENE (EPTFE) MEMBRANES in the t reatment of mucogingival problems such as gingival recession, has been recently described. The major issues raised dealt with creating and m aintaining space under the membrane and designing a flap that could be coronally positioned and at the same time capable of maintaining a go od blood supply. The authors proposed the use of a trapezoidal flap, a nd some technical space-making solutions, such as the use of a suturin g technique and different metal structures to support the membranes.
