Resorbable Membrane for guiding bone regeneration (PCT/ES2013/070924) CSIC, in collaboration with the Andalusian Public Health System and the Universities of Seville and Cadiz, has developed a fabrication method of polymeric membranes which, being biodegradable and resorbable, are especially suited for the promotion of guided bone regeneration. The method, based on the plasma treatment of one the surfaces of the membrane and the plasma deposition of nanometric layers of a bioactive oxide material on the other, permits to control the degradation of the implanted material and favors the formation of bone tissue without requiring the removal of the membrane.
