Figure 2From: Biocompatibility and resorption pattern of newly developed hyaluronic acid hydrogel reinforced three-layer poly (lactide-co-glycolide) membrane: histologic observation in rabbit calvarial defect modelRabbit calvarial defect model. (A) Critical size calvarial defects (8 mm diameter) were created, two defects on each side of the sagittal suture. (B) Four defects were covered with different membranes, where BG: Bio-Gide®; C: Monolayer PLGA membrane; 5%: 3-layer PLGA membrane (5% HA gel); and 10%: 3-layer PLGA membrane (10% HA gel).Back to article page
