Designed for the healthy development of bone and periodontal support tissue. Composed of a poly (lactic acid) based synthetic polymer that is biocompatible and resorbable with an excellent safety profile in medical applications. The outer surface of the Powerbone Barrier Membrane consists of a compressed (non-porous) poly (lactic acid) (PLA) layer which is placed next to the soft tissue to exclude epithelial and bioclast cells from the site. The inner surface of the bone graft Barrier Membrane faces the bony surface and consists of porous poly (lactic acid) (PLA) microbes which induce mesenchymal stem cell retention, proliferation and decentration. The three-layered structure of Powerbone Barrier Membrane prevents the migration of epithelial and bioclast cells, selectively supporting the healthy development of bone and periodontal tissues. Powerbone Barrier Membrane preserves its structure for 10-12 weeks and is completely absorb. - Size: 15 x 20 mm.
