摘要：
An improved implant is provided for human implantation, such as a spinal implant for implantation into the intervertebral space between two adjacent vertebrae. Some embodiments include a substrate of high strength biocompatible material, such as doped silicon nitride ceramic for example. In some embodiments, the substrate may also include one or more regions of a controlled porosity analogous to natural bone. In other embodiments, the substrate may comprise the entire implant.
