Guided Bone Regeneration (GBR) is used to handle this situation. The principle of GBR is to use a membrane to prevent the colonization of soft tissue cells of the bone defect and favors the migration of osteogenic linages. Currentmembranes do not completely fulfill the requirements that an optimal membrane should have, sometimes resulting in non-predictable results. Thus, the need to develop an ideal membrane to perform this duty is clear. Recent developments in bio-manufacturing are driving innovations in membranes technology permitting the active participation of the membrane in the healing and regenerative process trough native tissue mimicking, drug-delivery and cells interaction, away from being a passive barrier. New membranes features need specific evaluation techniques, beyond the International Standard for membrane materials (last reviewed in 2004), being this the rationale for the present review.Nanotechnology application has completely shifted the way of analyzing structural characterization. New progresses on osteoimmmunomodulation have also switched the understanding of cells-membranes interaction. Data and Sources:To propose an updated protocol for GBR membranes evaluation, critical reading of therelevant published literature was carried out after a MEDLINE/PubMed database search. Conclusions:The main findings are that a potential active membrane should be assessed in its nanostructure, physicochemical and nanomechanical properties,bioactivityand antibacterial,osteoblasts proliferation, differentiation and mineralization.
