摘要：
An interbody spinal implant having at least three distinct surfaces including (1) at least one integration surface having a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures； (2) at least one graft contact surface having a coarse surface topography including micro features and nano features； and (3) at least one soft tissue surface having a substantially smooth surface including nano features. Also disclosed are processes of fabricating the different surface topographies, which may include separate macro processing, micro processing, and nano processing steps.
