Introduction: The use of physical barriers to isolate cells with regenerating interest and prevent the penetration of cells inappropriate to the repair has been demonstrated over the past few decades. The use of membranes on bone reconstructions has important benefits. The barrier membranes can be non-absorbable or absorbable, which have collagen of bovine and swine as the most used material in its structure. Objective: The objective of this work is to present through a literature review the main features of the membranes used in guided bone regeneration (GBR), their indications, advantages, disadvantages and clinical applications. Discussion: the size of the reconstruction is also a factor that can influence the relative time of resorption and need for barrier, also the use of double-layer membrane can favor the barrier action, and maybe change the pattern of reabsorption. Conclusions: Literature demonstrates that the presence of membrane preserves the grafted volume, especially when positioned in double layer. More research regarding the recommended barrier time and degradation of absorbable membranes are still necessary.
