Bio-Gide is a resorbable collagen membrane used to guide tissue regeneration. Its two-layer design features a smooth, dense outer surface and a porous inner surface. The dense side acts as a barrier to prevent soft tissue from invading the regeneration site, while the porous side promotes tissue integration and vascularization. This bilayer arrangement also lends tearing resistance and good handling during placement and suturing. It’s a membrane, not a bone graft material, and it’s used to support regeneration, not exclusively hard-tissue repair. So, describing its bilayer structure and tear-resistant design matches its true properties.
