An implantable device comprising:: a body, the body defining a designed surface topography of bone-contacting features and being sized for placement into an intravertebral disc space, the designed surface topography having a defined, repeating, three-dimensional pattern, the three dimensional pattern resulting from the application to a respective surface of the body of first, second and third two-dimensional dimple surface patterns; the body having a top surface, a bottom surface, opposing lateral sides 30, and opposing anterior 40 and posterior 50 portions wherein the designed surface topography is provided on at least a portion of both the top surface and of the bottom surface each said first, second and third dimple surface patterns having a depth dimension, the first pattern depth dimension being greater than the second pattern depth dimension and the second pattern depth dimension being greater than the third pattern depth dimension to create a surface area of bone-contacting features that allow for in-growth and biological attachment to a biocompatible material, the designed surface topography being produced by overlapping a first, a second and a third feature (82, 84, 86), said first, second and third features (82, 84, 86) having different depth, the first feature being the deepest feature of the designed surface topography. the second feature being the second deepest feature of the designed surface topography, the third feature being the shallowest feature of the designed surface topography, wherein the depth and placement of the second feature are selected so that the second feature does not directly overlap and wipe out the first feature and the depth and placement of the third feature are selected so that the third feature does not directly overlap and wipe out the first feature or the second feature the designed surface topography allowing for initial stabilization and long-term bone in-growth and fusion. a body, the body defining a designed surface topography of bone-contacting features and being sized for placement into an intravertebral disc space, the designed surface topography having a defined, repeating, three-dimensional pattern, the three dimensional pattern resulting from the application to a respective surface of the body of first, second and third two-dimensional dimple surface patterns; the body having a top surface, a bottom surface, opposing lateral sides 30, and opposing anterior 40 and posterior 50 portions wherein the designed surface topography is provided on at least a portion of both the top surface and of the bottom surface each said first, second and third dimple surface patterns having a depth dimension, the first pattern depth dimension being greater than the second pattern depth dimension and the second pattern depth dimension being greater than the third pattern depth dimension to create a surface area of bone-contacting features that allow for in-growth and biological attachment to a biocompatible material, the designed surface topography being produced by overlapping a first, a second and a third feature (82, 84, 86), said first, second and third features (82, 84, 86) having different depth, the first feature being the deepest feature of the designed surface topography. the second feature being the second deepest feature of the designed surface topography, the third feature being the shallowest feature of the designed surface topography, wherein the depth and placement of the second feature are selected so that the second feature does not directly overlap and wipe out the first feature and the depth and placement of the third feature are selected so that the third feature does not directly overlap and wipe out the first feature or the second feature the designed surface topography allowing for initial stabilization and long-term bone in-growth and fusion.
