Process of fabricating implants having three distinct surfaces

a technology of three distinct surfaces and implants, applied in the field of spinal implants having at least three distinct surfaces, can solve the problems of impaired discs, affecting the anatomical functions of vertebrae, and affecting the health of discs, so as to avoid unintentional laceration or abrasion of delicate soft tissues, improve the effect of bone remodeling and fusion response, and improve the effect of fusion

Abstract

Processes of fabricating different surface topographies, which may include separate macro processing, micro processing, and nano processing steps, in order to produce 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.

[0002] The present invention relates generally to interbody spinal implants and methods of making such implants and, more particularly, to spinal implants having at least three distinct surfaces.BACKGROUND OF THE INVENTION

[0003] In the simplest terms, the spine is a column made of vertebrae and discs. The vertebrae provide the support and structure of the spine while the spinal discs, located between the vertebrae, act a...
