CYTOFLEX® is Ti-Enforced® ePTFE membranes are a multi-layer, non-resorbable membrane intended to be surgically placed under the muco-periosteum to aid in tissue regeneration in accordance with the guided tissue regeneration principle. It is a barrier material with a titanium frame enclosed within two layers of ePTFE material. The titanium reinforcement is intended for space and shape maintenance to contain bone grafting material and to minimize graft movement during wound healing. The membranes are designed to block bacteria penetration, and impede the migration and establishment of gingival tissue derived cells into bony defects. This provides a more favorable environment for neovascularization and for bone derived cells to repopulate and repair the defect. The Ti-Enforced® membranes are textured on both surfaces to improve handling and adhesion between tissue and membrane.
