Claim 6:
7. An expandable implant comprising:
a front ramp having at least one ramped surface and a rear ramp having at least one ramped surface;
a central drive screw retained in the rear ramp and threadedly engaged with the front ramp;
an upper endplate and a lower endplate, each slidably engaged with the ramped surfaces of the front and rear ramps, respectively, wherein rotation of the central drive screw moves the front ramp toward the rear ramp forcing the upper and lower endplates outward, thereby expanding a height of the implant; and
a reverse dynamization component located along the central drive screw, the reverse dynamization component being flexible to provide for micro-motion for a given period of time, and subsequently, stiffens to rigidly fix the upper and lower endplates
wherein the reverse dynamization component is formed of a two-part curing material with each part housed in separate compartments separated by a barrier, and when the barrier breaks and the two-parts mix, the resulting mixture cures and stiffens.
