Abstract
Context: This article reviews the available evidence about the barrier membranes utilized in Guided Tissue Regeneration process to prevent the migration of unfavorable cells to the wound area.
Evidence Acquisition: Available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered.
Results: A large number of existing membranes with different features and compositions may lead to different study results; none of the available membranes can result in %100 predictable outcomes.
Conclusions: Effectiveness of membranes in treating intrabony defects is very controversial; however, treating furcation defects using membranes was reported to be successful in a large number of studies.
