Barrier Membrane

A surgical blockade used in Guided Bone Regeneration (GBR). It is placed over a bone graft site to separate the slow-growing bone cells from the fast-growing gingival (gum) tissue.

Why It Matters

Gingival tissue grows much faster than bone. Without a physical barrier, soft tissue would migrate into the bone defect, preventing the graft from solidifying into hard bone capable of supporting an implant.

Clinical Details

• Resorbable Membranes: Made of collagen (porcine or bovine) or synthetic polymers; these dissolve naturally over 3–6 months.
• Non-Resorbable Membranes: Made of PTFE or Titanium; utilized for large vertical defects and require surgical removal.

FAQ

What is a barrier membrane?

It is a biological or synthetic "shield" that creates a secluded space, allowing bone progenitor cells to populate the graft site without competition from gum tissue.
