Composite material for tissue restoration

A method for performing a cosmetic procedure or a reconstructive procedure, comprising:

• implanting or injecting an effective amount of a three-dimensional scaffold complex into tissue to thereby distend it, wherein the scaffold complex comprises a hydrogel material network with polymeric fibers, wherein the scaffold complex comprises a crosslinking moiety present in an amount effective to introduce bonding within the hydrogel material,
• wherein the polymeric fibers are uniformly dispersed throughout the hydrogel network material, and wherein the polymeric fibers are covalently linked to the hydrogel material,
• wherein a plurality of pores are present on a surface of the scaffold complex at a concentration of at least about 50 pores per cm2 of the surface, and at least 80% of the pores have an average pore diameter on the surface that is at least about 5 microns, and
• wherein the polymeric fibers comprise a mean diameter of from about 100 nm to about 8000 nm, and wherein the polymeric fibers comprise a mean length of less than 500 micrometers.
