Two-layer synthetic membrane designed for guided tissue and bone regeneration. Compatible with RTR+ material and any other bone graft material. Fully resorbable meaning there is no need for repeated surgery. The membrane resorption time of 4 to 6 months provides optimal conditions for bone regeneration. Fully synthetic, which eliminates any biological risk associated with products of animal origin and ensures the universality of the material, making the product suitable for use on every patient. Two-layer structure ensures full impermeability and a strong barrier effect for 4 weeks. Compact layer protects against mucosal ingrowth into the defect area; porous layer provides support for bone cells during growth and promotes osseointegration. Easy to prepare and handle because the membrane maintains the same properties when dry and when wet. Insensitive to salivary enzymes. Easy to fit in the patient's mouth. No need to stabilise the membrane with pins or sutures.
