Synthetic, resorbable, and bilayer membrane that provides the correct conditions for bone regeneration. Completely resorbable: no second surgery is required, with a resorption time of 4 to 6 months, ensuring validated performance for bone regeneration. Fully synthetic to eliminate health risks associated with animal-derived materials and suitable for all patients. The bilayer structure allows for complete impermeability and a strong barrier effect for 4 weeks. The dense layer prevents the growth of gingival tissue instead of bone, while the porous layer allows bone cells to adhere and develop. R.T.R.+ Membrane is resistant to salivary enzymes, so in the event of wound dehiscence, it can remain in place to protect the graft and guide tissue healing. Easy to use and handle. R.T.R.+ Membrane has the same properties whether dry or wet. Easy adjustment directly in the mouth. No suturing or fixation is necessary. Compatible with R.T.R.+ or any bone graft material.
