Composite implants having integration surfaces composed of a regular repeating pattern

A composite interbody spinal implant comprising:

• a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, and a single vertical aperture;
• a first integration plate affixed to the top surface of the body and a second integration plate affixed to the bottom surface of the body, wherein the first integration plate and the second integration plate each have a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, and a single vertical aperture extending from the top surface to the bottom surface and aligning with the single vertical aperture of the body,
• wherein the top surface of the first integration plate and the top surface of the second integration plate each have a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures, wherein, when the implant is placed between a first vertebrae and a second vertebrae adjacent to the first vertebrae, with the first integration plate contacting the first vertebrae and the second integration place contacting the second vertebrae, migration-inhibiting friction is generated between the first vertebrae and the first integration plate and between the second vertebrae and the second integration plate.
