Cytoflex Mesh is made of pure titanium. The flexible gold-color, thin titanium mesh can be easily trimmed and tucked beneath the gingival flap with ease. Cytoflex Mesh is micro porous, allowing intimate diffusion of body fluids through the mesh, while resisting the integration of tissue within the mesh. Each box of Cytoflex Mesh contains 5 sterile, individually double-pouched 20mm x 25mm mesh. Expires in 2015.
