New Resorbable Membrane Materials for Guided Bone Regeneration

Membranes are used for guided bone regeneration (GBR) in bone defects. Resorbable membranes of collagen or aliphatic polyesters that do not require secondary surgery for removal, unlike non-resorbable membranes, have been marketed for GBR. Platelet rich fibrin membrane and silk-based membranes have recently been assessed as membranes for GBR. Studies have been conducted on resorbable membranes with new materials to improve physical properties and bone regeneration without any adverse inflammatory reactions. However, clinical research data remain limited. More studies are needed to commercialize such membranes.
