Resorbable Barrier Membrane 20 mm x 25 mm, 1/Pk. Synthetic microporous barrier membrane. Designed to enhance the adhesion of host cells, and at the same time provide a favorable environment for neo-vascularization and repopulation of bone cells to regenerate osseous tissue. The flexible barrier membranes are easily adaptable to tissue contours, yet offer sufficient duration to protect the bony defect from the intrusion of risks and soft tissue. Do not require a second retrieval procedure.
