DANUT VASILE, GEORGE IANCU, RALUCA CLAUDIA IANCU, DRAGOS VIRGIL DAVITOIU MAIN CHARACTERISTICS FOR MATERIALS USED AS SYNTHETIC SURGICAL MESHES Synthetic meshes are steadily developed and optimized to provide the best biocompatibility, resistance and elasticity with minimal side effects when used in vivo. This article presents mesh parameters, which influence the biological outcomes in surgical cases. Material, structure, resistance to the applied force, elasticity and biocompatibility are listed below in order to clarify the advantages and shortcomings of different mesh types. Future developments in synthetic mesh industry are presented as well in order to improve mesh acceptability in vivo and optimize healing process. There is no ideal mesh, but only prostheses with fewer side effects when correctly used, in accordance with patient needs.
