Comparative Evaluation of the Physical Properties of Membranes for Periodontal Regeneration: an in Vitro Study

Introduction: Barrier membranes are the devices used in guided tissue regeneration procedures to promote the repopulation of the wound space by periodontal ligament cells. Commercially available membranes have been used widely for periodontal regeneration. The aim of the present study is to compare and evaluate the physical properties of membranes used for periodontal regeneration. Materials and Methods: The tensile strength and surface topography using scanning electron microscope were analysed of three commercially available membranes: chorion membrane, Healiguide™ membrane and PerioCol®-GTR membrane were analysed. Results: The tensile strength of the PerioCol®-GTR membrane was the highest, while that of the Chorion membrane was the least. Variations in the surface topography were observed in all three membranes groups. Conclusion: The study demonstrated variation in surface topography and tensile strength of the resorbable periodontal membranes, suggestive of differences in the time of resorption during regenerative periodontal procedures.
