PURPOSE: To evaluate several physical properties and physical dimensions of commercially available soft-tissue augmentation devices. METHODS: After 2 x 5-cm strips of several graft materials were hydrated, load elongation, cyclic and permanent displacement, percent elastic displacement, tensile modulus, stiffness, and ultimate load-to-failure strength were determined. With a 5-N preload, 30 cyclic loads between 5 N and 50 N were applied at 12.5 mm/s followed by destructive testing...
