Implant frames for use with settable materials and related methods of use

An intervertebral implant system for intervertebral implantation, comprising:

• A first ribbon-like or band-like frame having a first peripheral wall defining a first space therein, a second ribbon-like or band-like frame having a second peripheral wall defining a second space therein;
• and
• first and a second settable materials that are introduced into the first and second spaces, respectively of the first and second ribbon-like or band like frames,
• wherein the first ribbon-like or band-like frame includes a pair of free ends joinable to one another, or at least one opening in the first peripheral wall, and the second ribbon-like or band-like frame includes a pair of free ends joinable to one another, or at least one opening in the second peripheral wall, and the first and second materials include at least one of bone, composites, polymers of bone growth material, collagen, and insoluble collagen derivatives;
• and wherein the first and second settable materials each have an initial fluid condition and are cured to a hardened condition in the first and second spaces respectively, wherein the settable material in the first space is harder and has a different porosity than the settable material in the second space.
